Detailed Description

The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.

The water purification system provided by the invention can be used for purifying the laundry wastewater in practical use. Referring to fig. 7 and 8, a structure of the water purifying system includes a purified water chamber communicating with the filter chamber through a drain pipe 12, a filter chamber having a drain port at a highest point of a passage in the drain pipe 12 in a height direction of the purified water chamber higher than that of the purified water chamber, and a drain pump 27 having a drain port communicating with the drain port of the filter chamber to enable introduction of the purified water in the purified water chamber into the filter chamber, as shown in fig. 7.

Because the water purification cavity of the water purification system is communicated with the filter cavity through the drain pipe 12, and the highest point of the channel in the drain pipe 12 is higher than the height of the water purification cavity in the height direction of the water purification cavity, the washing drainage is filled into the water purification cavity and then is filled, and does not flow into the filter cavity through the drain pipe, but is sucked into the filter cavity through the drain pipe under the traction of the drain pump to be purified by the filter unit in the filter cavity and then discharged after being purified by the filter unit in the filter cavity for the second washing or rinsing, so that the water consumption is greatly saved, the expenditure is also saved for users, and the influence on the surrounding environment caused by the fact that the washing wastewater is directly discharged to the outside is avoided.

The laundry wastewater may be directly poured into the clean water chamber 2 through the open upper end of the clean water chamber and then purified by the water purification unit provided in the precipitation chamber 2, or may be injected into the clean water chamber 2 through a clean water chamber injection port 28 in the wall of the clean water chamber 2, preferably the top wall of the clean water chamber.

Of course, as shown in fig. 8 and 10, the drain port of the drain pump 27 may be connected with a water pipe 321 to introduce the purified and filtered water into a desired container to be stored or into a washing chamber of the laundry device to participate in washing again or to be directly drained.

Further, a drain pipe 12 is provided on an outer side surface of the water purifying bottom case forming the water purifying chamber, as shown in fig. 7, and one end of the drain pipe 12 is connected to the bottom of the water purifying chamber 2, so that the washing wastewater injected into the water purifying chamber 2 does not automatically flow into the filter chamber beyond the highest point of the passage in the drain pipe even if it crosses the chamber wall of the water purifying chamber.

Of course, the drain pipe 12 can have various configurations, for example, as shown in FIG. 8, in one embodiment, the drain pipe 12 is a U-shaped pipe, wherein the U-shaped pipe has an open end facing downward in the height direction of the clean water chamber, and one end of the U-shaped pipe communicates with the bottom of the clean water chamber and the other end extends downward and communicates with the top of the filter chamber through a pipe 122. Thus, along the water flow direction, the water level in one side pipe section of the U-shaped pipe is the same as that of the water purification cavity, and meanwhile, under the traction of the drainage pump, the other side pipe section extending downwards of the U-shaped pipe can enable the water flow to have gravitational potential energy flowing downwards, so that the drainage pump 27 can more easily introduce the water flow into the filtering cavity, and the power consumption is reduced.

In addition, after a period of use, some dirt or impurities can accumulate in the water purifying cavity and the filter cavity, and in order to improve the water purifying effect, the dirt or impurities need to be discharged.

The clean water chamber and filter chamber waste fitting assembly may be located anywhere, for example, in one embodiment, at the bottom of the clean water chamber and filter chamber as shown in fig. 10 for later replacement and maintenance convenience. In this way, the water purification system can be easily laid down for replacement or repair, as shown in fig. 10. In addition, under the condition that the strength of the water purification cavity pollution discharge assembly and the filter cavity pollution discharge assembly is met, the water purification cavity pollution discharge assembly and the filter cavity pollution discharge assembly can also provide auxiliary support for the water purifier with the water purification cavity and the filter with the filter cavity.

In addition, the clean water chamber blowdown assembly and the filter chamber blowdown assembly may be of any type, for example, as shown in fig. 10, in one embodiment, the clean water chamber blowdown assembly includes a clean water chamber tractor 17 such as a priming pump or priming impeller and a clean water chamber blowdown pipe 18 connected to the clean water chamber and capable of opening and closing; the filter cavity sewage discharging assembly comprises a filter cavity tractor 19 which is connected with the filter cavity and can be opened and closed, such as a water diversion pump or a water diversion impeller, and a filter cavity sewage discharging pipe 20; wherein the clean water cavity sewage draining pipe 18 and the filter cavity sewage draining pipe 20 are connected with a sewage draining joint 21. Therefore, the water cleaned from the water purifying cavity and the filter cavity can be gathered at the sewage draining joint 21 and then discharged.

In addition, in order to facilitate the cleaning of the clean water chamber and the filter chamber, it is preferable that the water purification system further includes a cleaning pipe 22 communicating with the clean water chamber and the filter chamber, as shown in fig. 8 and 9, the cleaning pipe 22 is provided with an inlet valve 23 and an inlet check valve 24 for preventing the backflow of the inlet water, for example, in the structure shown in fig. 8 and 9, the cleaning pipe 22 is connected with a four-way joint 29, the four-way joint 29 communicates with the filter chamber through a pipe 223, and communicates with the clean water chamber through a pipe 222 and a pipe 221, respectively, to inject the cleaning water for cleaning.

Further, as shown in fig. 1 and 3-5, a float accommodating cavity 8 is formed outside the pure water cavity 2, wherein the cleaning pipe 22 and the float accommodating cavity 8, for example, the four-way joint 29 is respectively communicated with the float accommodating cavity 8 outside both sides of the pure water cavity through a pipeline 222 and a pipeline 221, so that cleaning water can overflow into the pure water cavity to clean the pure water cavity after filling the float accommodating cavity 8, and the float outlet 9 of the float accommodating cavity 8 is communicated with a sewage connector 21 of the pure water system, for example, through a pipeline 323 to connect with the sewage connector 21 to discharge the cleaning water in the float accommodating cavity 8.

Furthermore, the water purification system may be directly arranged in the structure of the washing machine, for example, may be arranged using the bottom space of the washing machine. Alternatively, in one embodiment, a single water purification device may include a water purification chamber and a filter chamber that are spaced apart. Alternatively, in an alternative embodiment, the water purification system includes a base (not shown) on which a water purifier 25 having a water purification chamber and a filter 26 having a filter chamber and a drain pump 27 are provided to form a water purification module. Such a water purification module can be manufactured, used, offered for sale, sold and imported separately and can be directly assembled as a module into a washing machine.

In addition, in the water purification system of the present invention, the floating scraper 1 may be disposed above the water purification chamber through a support structure, the support structure may be disposed inside or outside the water purification chamber, or may be suspended above the water purification chamber through another bracket, and the floating scraper 1 may perform a movement for scraping the floating objects on the upper portion of the water purification chamber 2 outside the water purification chamber 2 during water purification. Like this, laundry wastewater can pour into water purification chamber 2 and by the water purification unit 4 water purification treatment that sets up in water purification chamber 2, and in the purification treatment process, 2 upper portions in water purification chamber can produce the floater that the water purification reaction produced, and floater scraper blade 1 motion on 2 upper portions in water purification chamber then can be in time with the floater scrape out to water purification chamber 2 outsidely to promote water purification effect.

In addition, further, referring to fig. 1, the water purifier 25 includes a water purifying bottom case and a float blade 1, the float blade 1 is located above the purified water chamber 2 by a support structure provided on the water purifying bottom case, and the float blade 1 can perform a motion for scraping the float on the upper portion of the purified water chamber 2 outside the purified water chamber 2 in the water purifying process. This water purification drain pan 14 can assemble water purification unit 4 and set up in water purification chamber 2 in-service use, and laundry wastewater can pour into water purification chamber 2 in through water purification unit 4 water purification treatment, and in the purification treatment process, 2 upper portions in water purification chamber can produce the floater that the water purification reaction produced, and floater scraper blade 1 then can be outside water purification chamber 2 with the floater of scraping in time at the motion on 2 upper portions in water purification chamber to promote the water purification effect.

The movement of the float scraping plate 1 may be a reciprocating movement or may be a rotation so as to scrape the float on the upper portion of the clean water chamber 2 out of the clean water chamber 2.

In addition, the movement of the float scraper 1 can be driven in many ways, for example manually or by means of an electric motor.

Of course, after the floating object scraping plate 1 is disposed on the supporting structure, it can be driven by other driving members, for example, in an embodiment, a rack is disposed on the floating object scraping plate 1, and the motor is engaged with the rack through a gear to drive the rack to move back and forth, so as to drive the floating object scraping plate 1 to move back and forth.

Alternatively, in another embodiment, the support structure can drive the floating scraper 1 to move, that is, the matching relationship between the floating scraper 1 and the support structure enables the support structure to drive the floating scraper 1 to move while supporting the floating scraper 1. For example, in one embodiment, the floating object scraping plate is disposed on the rotating shaft, and the motor can drive the rotating shaft to rotate so as to drive the floating object scraping plate to rotate, so that the floating object is scraped out of the water purifying cavity 2. Or in another embodiment, the floater scraping plate is arranged on the rack, and the motor drives the rack to move through the gear so as to drive the floater scraping plate to move.

Further, in order to simplify the structure and improve the efficiency of the flotage scraping, it is preferable that the flotage scraper 1 is movable between opposite ends of the clean water chamber 2, for example, when the support structure is the rack as described above, the rack drives the flotage scraper to move from one end of the clean water chamber 2 to the other end and then back to the one end, and so on.

Of course, the float scraper 1 may have various structural forms, for example, in one form, the float scraper 1 may be a straight plate, that is, such that the plate surface of both ends of the float scraper 1 facing the clean water chamber 2 is a straight surface, so that the float scraper 1 can scrape the float outside both ends of the clean water chamber 2 when moving between both ends of the clean water chamber 2; or, in another form, the plate surfaces of both end portions of the float scraping plate 1 facing the clean water chamber 2 are formed as inclined surfaces, respectively, for example, the middle portion of the plate surface is projected forward and extends obliquely from the projected middle portion to the side surfaces toward both sides to form inclined surfaces at both sides, so that the float can be scraped to both sides outside of the clean water chamber 2 by the inclined surfaces at both sides.

Or, in an alternative embodiment, as shown in fig. 1, the support structure includes a screw rod 3, both ends of the screw rod 3 are rotatably disposed on the opposite end walls 5 of the clean water bottom case and above the clean water chamber 2, a screw hole is formed on the float plate 1, the float plate 1 is disposed on the screw rod 3 by the cooperation of the screw hole and the screw rod, the screw rod 3 can move the float plate 1 when rotating, so that the screw rod 3 can be manually driven or the screw rod 3 can be driven to rotate by a motor, since the blocking of the float plate 1 by the side wall of the clean water chamber 2 (of course, the blocking of the float plate 1 by the side wall of the clean water chamber 2 is larger than the width of the clean water chamber 2, that is, larger than the distance between the inner surfaces of the opposite side walls of the clean water chamber 2) or the blocking of the float plate 1 by the opposite side walls of the clean water bottom case, by the cooperation of the screw, the rotary motion of the screw 3 can be converted into the movement of the floating object scraper, and the positive and negative rotation of the screw 3 can drive the floating object scraper 1 to move back and forth.

Further, both ends of the float plate 1 (i.e., both ends extending in the direction between the opposite side walls of the clean water chamber 2) are slidably supported on the opposite side walls 6 of the clean water chamber 2; like this, two lateral walls 6 of intake antrum 2 can block floater scraper 1 and rotate along with the screw rod, also can play certain supporting role to floater scraper 1 to make floater scraper 1 keep straight and can not incline. And/or, in order to connect the motor 15, one end of the screw rod 3 extends out from the corresponding end wall 5 to form an extending section, and the extending section is provided with the driven gear 7, so that the driving gear 16 on the output shaft of the motor 15 is meshed with the driven gear 7 to drive the screw rod 3 to rotate, and the positive and negative rotation of the motor 15 can drive the screw rod to rotate positively and negatively to drive the floater scraping plate 1 to move back and forth.

Of course, the motor 15 may be disposed on the water purification bottom case and may be located inside or outside the water purification bottom case, or the water purifier 25 includes a water purification cover 13 capable of covering the water purification bottom case, wherein the motor 15 is disposed on the water purification cover 13, and the motor 15 can drive the supporting structure to move so as to drive the floating object scraper 1 to move. For example, the motor 15 may be disposed on the water purifying cover 13, and when the water purifying cover 13 is covered on the water purifying bottom case, the driving gear 16 disposed on the output shaft of the motor 15 is engaged with the driven gear 7.

In addition, in order to facilitate the control of the reciprocating movement of the floating object scraper 1, as shown in fig. 4, 5 and 6, preferably, the water purifying bottom case 14 includes a first micro switch located at one end of the water purifying cavity 2 and a second micro switch located at the other end of the water purifying cavity 2, wherein the supporting structure drives the floating object scraper 1 to move to trigger the first micro switch and then drives the floating object scraper 1 to move reversely until the second micro switch is triggered and then moves reversely again, for example, the screw 3 drives the floating object scraper 1 to move to trigger the first micro switch, the control unit receives a signal of the first micro switch and controls the motor to drive the screw to rotate reversely so as to drive the floating object scraper 1 to move towards the other end of the water purifying cavity 2 until the second micro switch is triggered, the control unit receives a signal of the second micro switch and controls the motor to drive the screw to rotate reversely again, so as to realize the reciprocating movement of the floating object scraping plate 1 to scrape the floating objects.

In addition, the floater scraping plate 1 may directly scrape the floater out of the water purifying bottom case, or, in order to collect the floater, it is preferable that a floater receiving cavity 8, which is located outside the water purifying cavity 2 and has the same cavity wall as the water purifying cavity 2, is formed in the water purifying bottom case 14, so that the floater scraping plate 1 can scrape the floater into the floater receiving cavity 8.

The specific position of the float receiving cavity 8 may be set according to the movement locus of the float scraping plate 1 and the shape of the float scraping plate 1, for example, in the exemplary structure shown in fig. 1 and 4, the float receiving cavity 8 is formed outside both ends of the clear water cavity 2, so that the screw 3 drives the float scraping plate 1 to reciprocate, and the float can be scraped into the float receiving cavities 8 at both ends.

Further, preferably, referring to fig. 1, 2 and 3, in order to facilitate the discharge of the float in the float receiving chamber 8, the chamber bottom surface of the float receiving chamber 8 is continuously inclined toward the lowest place, and a float discharge port 9 communicating with the outside of the clean water bottom case is formed at the lowest place. Thus, the float scraped into the float receiving chamber 8 flows into the lowest position and flows out when the float discharge port 9 is opened, and can be discharged through the pipe 323 or entered into the collection container.

Of course, the lowest portion of the cavity bottom surface of the float receiving cavity 8 may be formed at any position, for example, at the middle portion of the cavity bottom surface of the float receiving cavity 8 such that both side portions of the cavity bottom surface located at the middle portion form an inclined surface, or may be formed at one end of the cavity bottom surface of the float receiving cavity 8, as in the structure shown in fig. 1, 2 and 3, such that the cavity bottom surface of the float receiving cavity 8 is integrally formed as one inclined surface.

In addition, the floater accommodating chamber 8 may be formed in various manners, for example, in one manner, partition plates may be inserted into both ends of the inner space of the water purification bottom case, respectively, so that a water purification chamber is formed between the two partition plates, and the floater accommodating chamber 8 is formed between the partition plates and the end wall of the water purification bottom case. Or, in another mode, as shown in fig. 1, 2 and 3, the upper part of the wall of the purified water bottom case protrudes outwards to form a step wall 10 in the purified water bottom case, a partition plate 11 is arranged at the step wall 10, a floater accommodating chamber 8 is formed between the partition plate 11 and the upper part of the wall of the purified water bottom case, the inner surface of the partition plate 11 is flush with the inner surface of the lower part of the wall of the purified water bottom case, and the floater accommodating chamber 8 and the purified water chamber 2 share the partition plate 11 as the same wall; and the step wall 10 extends obliquely to form the lowest position of the floater accommodating chamber 8, so that a reinforcing plate can be arranged between the step wall 10 and the lower part of the shell wall of the water purification bottom shell while the volume of the floater accommodating chamber 8 is satisfied, so that the lower part of the shell wall of the water purification bottom shell is reinforced while the step wall 10 is supported, and meanwhile, the lower part of the shell wall of the water purification bottom shell can be protected to avoid the direct collision of the lower part of the shell wall of the water purification bottom shell.
