Description

Technical Field

[0001] The present invention relates to the technical field of water purifiers, and particularly relates to a water circuit structure of a water purifier and a combined water purifying and washing machine including the same. Background Art

[0002] Generally, a water purifier can only produce filtered normal temperature water or heated water for drinking. The water purification faucet is generally installed on the kitchen sink. With the improvement of living quality, in addition to drinking, users also have corresponding higher requirements for cleaning. For example, there are needs to wash fruits, vegetables, meat, rice, etc. at this position, and they hope to wash them cleaner. Although the pure water produced by filtration has better water quality, when washing the above-mentioned food materials, not only better water quality is required, but also water with certain cleaning ability is needed, such as bubble water. When bubble water is used to wash fruits and vegetables, it can destroy the adhesion of pesticide residues, and the inactivated pesticide molecules are stripped from the food materials along with the water flow, restoring the clean state of the food; it can also strongly wash the food materials to ensure food hygiene, quickly wash tableware, easily remove oil and sterilize; and purify meat food materials to wash away hormone residues.

[0003] However, whether it is a water purifier that can produce bubble water or a water purifier that can only produce pure water, there is a need to regularly replace the filter element during use to ensure that the pure water or bubble water meets the needs of users. On the one hand, replacing the filter element requires manual operation by the user, which has a certain degree of difficulty. On the other hand, regularly replacing the filter element will make the user's usage cost remain high. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects that the cost of regularly replacing the filter element of the water purifier in the prior art is high and the manual replacement of the filter element is relatively complicated, and to provide a water circuit structure of a water purifier and a combined water purifying and washing machine including the same.

[0005] The present invention solves the above technical problems through the following technical solutions:

[0006] A water circuit structure of a water purifier, the water inlet end of the water circuit structure of the water purifier is communicated with a water source, the water outlet end of the water circuit structure of the water purifier is communicated with a faucet, and the water circuit structure of the water purifier includes:

[0007] A main water circuit, a booster pump, a second filter element and a waste water solenoid valve are sequentially communicated on the main water circuit. The water flow of the water source enters the second filter element through the booster pump and generates pure water and waste water. The waste water is discharged through the waste water solenoid valve, and the pure water flows to the faucet;

[0008] The first branch is located between the water source and the booster pump. The first branch is arranged in parallel with the main water path and is used to generate sparkling water. The booster pump is configured to continue operating when the faucet is closed and allow the sparkling water to enter the second filter element and then be discharged through the wastewater solenoid valve.

[0009] In this solution, by setting the main water path, the water flow from the water source can generate pure water for users to drink and discharge the wastewater in a timely manner. A first branch is arranged in parallel on the main water path. On the one hand, the first branch can generate sparkling water for users to wash food ingredients. The cleaning ability of sparkling water for food ingredients is better than that of pure water. On the other hand, in addition to cleaning, the sparkling water can also be introduced into the second filter element, so that the sparkling water with cleaning ability can clean the impurities in the second filter element after entering the second filter element, so as to reasonably utilize the generated sparkling water without waste, and can make the service life of the second filter element increase correspondingly compared with the way of regular replacement and ensure that its filtering ability is not affected, extend the replacement cycle of the second filter element, reduce the user's usage cost, and improve the user's usage experience.

[0010] Preferably, the main water path further includes a first filter element and a first solenoid valve. The first solenoid valve is arranged between the booster pump and the water source, and the first filter element is arranged between the first solenoid valve and the water source.

[0011] In this solution, by setting the first filter element, the water flow entering the booster pump can be filtered. The quality of the pure water generated by the cooperation of the first filter element and the second filter element is also correspondingly improved, avoiding blocking the booster pump and increasing the service life of the booster pump.

[0012] Preferably, the water path structure of the water purifier further includes a second branch. The second branch is located between the booster pump and the second filter element and is communicated with the main water path. A gas mixing chamber, a third solenoid valve and a bubbler are sequentially communicated on the second branch. When the first solenoid valve, the second channel of the faucet and the wastewater solenoid valve are closed and the first branch and the second branch are communicated, the second branch is used to supply sparkling water to the first channel of the faucet.

[0013] In this solution, by setting the second branch and communicating the second branch with the first branch, the sparkling water can flow out of the faucet for users to use, increasing additional usage scenarios in addition to pure water. The sparkling water generated by the first branch can increase the number of bubbles and make the bubble size smaller through the gas mixing chamber and the bubbler, thereby improving the cleaning ability of the sparkling water. The on-off of the second branch is controlled by the third solenoid valve to meet the user's demand for using sparkling water.

[0014] Preferably, the water circuit structure of the water purifier further includes a third branch. One end of the third branch is communicated with the main water circuit, and the other end of the third branch is communicated with the first channel. The third branch is arranged in parallel with the second branch. A one-way valve and a valve core are arranged on the third branch. When the second branch supplies the sparkling water to the first channel, the opening degree of the valve core is adjusted to adjust the flow rate entering the first channel.

[0015] In this solution, the faucet includes a first channel and a second channel. The first channel is used to flow out the sparkling water, and the second channel is used to flow out the pure water. By setting the third branch to adjust the valve core when supplying the sparkling water to the user, the user can obtain sparkling water with a larger flow rate, thereby improving the user experience.

[0016] Preferably, the water circuit structure of the water purifier further includes a fourth solenoid valve. The fourth solenoid valve is located between the waste water solenoid valve and the waste water outlet. After the sparkling water or the waste water is discharged from the waste water outlet, the fourth solenoid valve closes the waste water outlet.

[0017] In this solution, by setting the fourth solenoid valve, it is possible to avoid the situation where the water pressure in the main water circuit is low due to the continuous discharge of the waste water in the second filter element when the waste water solenoid valve is in a semi-open state. Furthermore, when the user closes the water circuit and takes water for the second time, the water pressure at the initial outflow of the faucet is guaranteed, and the situation of a relatively small initial water flow is reduced.

[0018] Preferably, a jet pump is arranged on the first branch. The air inlet of the jet pump is opened or closed through a second solenoid valve. When the second solenoid valve is opened, the first branch generates sparkling water.

[0019] In this solution, by setting the second solenoid valve to close the air inlet of the jet pump when the user does not need sparkling water, at this time, the main water circuit can generate pure water instead of sparkling water, which is convenient for the user to drink and prevents the bubbles in the water from affecting the user's drinking experience when drinking.

[0020] Preferably, a pressure reducing valve is further arranged on the first branch. The pressure reducing valve is arranged between the water source and the jet pump.

[0021] In this solution, by setting the pressure reducing valve to reduce the water pressure at the water inlet end of the jet pump, it is possible to avoid the influence on the efficiency of generating sparkling water when the water pressure is too high.

[0022] A combined water purifying and washing machine, the combined water purifying and washing machine includes the water circuit structure of the water purifier as described above.

[0023] In this solution, the integrated washer-dryer can produce pure water for drinking and also produce sparkling water for washing food ingredients. It has a higher degree of integration, and the way of mutual switching enables users to make independent choices and improve efficiency. In addition, the integrated washer-dryer includes the above-mentioned water purification machine waterway structure, so that the remaining sparkling water in the main waterway after the user finishes using the sparkling water can flush the filter element, thereby increasing the service life of the filter element, extending its replacement cycle, and reducing the user's usage cost.

[0024] Preferably, the integrated washer-dryer includes a bracket, a waterway board, a booster pump assembly, a main control board, and a water tank assembly that are connected in sequence. The waterway board and the water tank assembly are relatively arranged on both sides of the bracket. The booster pump assembly is located below the water tank assembly, and the main control board is located at the top of the bracket and on the side away from the water tank assembly.

[0025] In this solution, through the bracket, the waterway board, the main control board, the water tank assembly, and the booster pump assembly are integrally arranged in the integrated washer-dryer, reducing the space occupied by the integrated washer-dryer. In addition, the main control board is arranged away from the water tank assembly, which can prevent the electrically related parts of the integrated washer-dryer from failing when the water tank assembly leaks, improving the usage safety.

[0026] Preferably, the integrated washer-dryer further includes a buffer member. The booster pump assembly includes a booster pump and a housing. The housing covers the outer peripheral side of the booster pump. The buffer member is arranged between the surface of the housing and the booster pump, and / or the buffer member is arranged at the connection between the housing and the bracket.

[0027] In this solution, by setting the buffer member, the vibration transmission during the operation of the booster pump is reduced, preventing resonance between other connection structures and the booster pump, and at the same time, the noise generated during the operation of the booster pump can be reduced.

[0028] The positive and progressive effects of the present invention are as follows: By setting the main waterway, the water flow of the water source can produce pure water for users to drink and discharge the waste water in time. A first branch is connected in parallel on the main waterway. On the one hand, the first branch can produce sparkling water for users to wash food ingredients. The cleaning ability of sparkling water for food ingredients is better than that of pure water. On the other hand, in addition to cleaning, the sparkling water can also be introduced into the second filter element, so that the sparkling water with cleaning ability can wash the impurities in the second filter element after entering the second filter element, so as to reasonably utilize the generated sparkling water without waste, and it can make the service life of the second filter element increase compared with the way of regular replacement and ensure that its filtering ability is not affected, extend the replacement cycle of the second filter element, reduce the user's usage cost, and improve the user's usage experience.

[0070] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments described herein.

[0071] This embodiment provides a water purification machine water circuit structure. As shown in Figure 1 and Figure 2 , the water inlet end of the water purification machine water circuit structure is communicated with the water source 100, and the water outlet end of the water purification machine water circuit structure is communicated with the faucet 200. The water purification machine water circuit structure includes:

[0072] Main water circuit 1, on which a booster pump 2, a second filter element 3 and a waste water solenoid valve 4 are connected in sequence. The water flow of the water source 100 enters the second filter element 3 through the booster pump 2 and generates pure water and waste water. The waste water is discharged through the waste water solenoid valve 4, and the pure water flows to the faucet 200;

[0073] The first branch 10 is located between the water source 100 and the booster pump 2. The first branch 10 is arranged in parallel with the main water channel 1 and is used to produce bubble water. The booster pump 2 is configured so that when the faucet 200 is closed, the booster pump 2 continues to work and allows the bubble water to enter the second filter element 3 and then be discharged through the waste water solenoid valve 4.

[0074] Specifically, a pipeline is provided on the main waterway 1, and the pipeline is a soft pipe or a hard pipe in the prior art to realize water circulation. This embodiment is explained by taking the pipeline as a hard pipe as an example. The water source 100 is connected to the booster pump 2, and the booster pump 2 is a structure in the prior art, which will not be described in detail here. The booster pump 2 is connected to the second filter element 3, and the second filter element 3 is respectively connected to the wastewater solenoid valve 4 and the faucet 200. The above-mentioned connection relationship allows the water to flow into the main waterway 1 through the booster pump 2 to the second filter element 3. The second filter element 3 is an MNF filter element in the prior art. The MNF filter element contains ultrafiltration carbon rods so that the water flow can be filtered and produce pure water and wastewater. The pure water can meet the user's drinking needs and flows out through the second filter element 3 through the faucet 200. The excess wastewater is discharged to the sewer through the wastewater solenoid valve 4 to avoid wastewater accumulation. The water channel 1 is also provided with a first branch 10, which is arranged in parallel with the main water channel 1, that is, when water flows through the main water channel 1, the water can also enter the first branch 10 at the same time. The first branch 10 is used to produce bubble water. The first branch 10 arranged in parallel makes the process of the main water channel 1 producing pure water not affected by the first branch 10. Bubble water is a water flow containing bubbles in the prior art. Due to its own characteristics, bubble water can burst bubbles when washing food and take away dirt on the surface of the food, and the cleaning ability of bubble water for food is better than that of pure water, thereby For cleaning food, the first branch 10 is located between the water source 100 and the booster pump 2. The bubble water can be driven by the booster pump 2 to flow in the main water channel 1. The water channel structure of the water purifier can not only produce pure water, but also produce bubble water, which can meet the user's direct drinking needs and the user's needs for cleaning food. In the water channel structure of the water purifier, when the user turns off the faucet 200 after taking water, the booster pump 2 will continue to work. The time for the booster pump 2 to continue working can be preset, and it drives the bubble water in the pipeline to flow into the second filter element 3. That is to say, the bubble water generated in the pipeline will also clean the second filter element 3 after the user takes water, so as to reasonably utilize the generated bubble water and avoid waste, and prevent scale from clogging the second filter element 3. In addition, the bubble water that has flushed the second filter element 3 can also clean the waste water solenoid valve 4 when it is discharged through the waste water solenoid valve 4. In addition, compared with the method of regular replacement, the service life of the second filter element 3 can be increased accordingly and its filtering capacity can be guaranteed not to be affected, thereby extending the cycle of replacing the second filter element 3, reducing the user's use cost, and improving the user's use experience.

[0075] Further, the main water path 1 further includes a first filter element 5 and a first solenoid valve 6. The first solenoid valve 6 is disposed between the booster pump 2 and the water source 100, and the first filter element 5 is disposed between the first solenoid valve 6 and the water source 100.

[0076] Specifically, the first filter element 5 is a PCF filter element in the prior art. The PCF filter element is divided into an upper filter element and a lower filter element. Among them, the upper filter element of the first filter element 5 is communicated with the water source 100. After the water flows through the first filter element 5 for filtration, water with higher quality is obtained, so as to reduce the scale in the water when the water continues to flow into the booster pump 2, avoid blocking of the booster pump 2, and improve the service life of the booster pump 2. The lower filter element of the first filter element 5 is located between the second filter element 3 and the faucet 200. After the water passes through the second filter element 3 for filtration to generate pure water, the pure water passes through the lower filter element of the first filter element 5 and finally flows out from the faucet 200 for the user to use, so as to further improve the quality of the pure water and meet the user's direct drinking needs.

[0077] The first solenoid valve 6 provided on the main water path 1 is used to control the on / off of the main water path 1, so that when the first branch 10 is connected in parallel with the main water path 1, the user can switch between the generated bubble water and pure water. When the first solenoid valve 6 is closed, only bubble water is generated, and when the first branch 10 is closed, only pure water is generated, enriching the user's selection space. The first solenoid valve 6 is opened or closed through a control circuit in the prior art. The user can feed back the demand to the control circuit to achieve the above operations, which will not be elaborated here.

[0078] It can be understood that the flow path of the pure water is successively the water source 100, the upper filter element of the first filter element 5, the first solenoid valve 6, the booster pump 2, the second filter element 3, the lower filter element of the first filter element 5, and the faucet 200.

[0079] In this embodiment, as Figure 3 shown, the water path structure of the water purifier further includes a second branch 20. The second branch 20 is located between the booster pump 2 and the second filter element 3 and is communicated with the main water path 1. A mixing chamber 7, a third solenoid valve 8, and a bubbler 9 are successively communicated on the second branch 20. When the first solenoid valve 6, the second channel 202 of the faucet 200, and the waste water solenoid valve 4 are closed and the first branch 10 and the second branch 20 are communicated, the second branch 20 is used to supply bubble water to the first channel 201 of the faucet 200.

[0080] Specifically, the second branch 20 is used to supply bubble water to the first channel 201, and the bubble water does not pass through the second filter element 3, so as to avoid the situation that the bubble water is directly discharged from the waste water solenoid valve 4 and the user cannot obtain the bubble water. The second branch 20 is controlled to be on / off through the third solenoid valve 8 to avoid the bubble water flowing out from the faucet 200 when the user needs pure water. As Figure 10As shown, the gas mixing chamber 7 is a structure in the prior art for fully mixing bubbles and water, and its principle will not be elaborated too much here. The bubbler 9 is arranged close to the faucet 200, and two filters are arranged in the bubbler 9. A microporous structure and a pressure reducing structure are arranged between the two filters. A through hole is arranged in the middle area of the microporous structure, and a pressure reducing hole is arranged on the pressure reducing structure. The pressure reducing hole and the through hole are arranged in a staggered manner and at least partially overlap. When the incoming water pressure is relatively small, the water flow directly passes through the overlapping part after the two are installed. When the incoming water pressure is relatively large, the water flow impacts the connection part between the two and the non-overlapping part. Since both the microporous structure and the pressure reducing structure are made of silica gel, the overlapping part of the two is washed open by water. When the water flow passes through, it needs to pass through the blockage of the non-overlapping part and flow through the through hole and the pressure reducing hole with complete size, thereby reducing the water pressure flowing to the faucet 200 and finally ensuring the release effect of the bubble water. The microporous structure and the pressure reducing structure are both structures in the prior art and will not be elaborated too much here. It should be noted that the first branch 10 can generate bubble water without being connected to the second branch 20. By being connected to the second branch 20, the water flow passes through the gas mixing chamber 7 and the bubbler 9 in sequence, enabling the gas and water to be fully mixed to obtain micro-nano bubble water, so as to improve the cleaning ability of the bubble water, so that the bubble water flowing to the faucet 200 through the second branch 20 can meet the user's need to clean food ingredients.

[0081] The faucet 200 in this embodiment includes a first channel 201 and a second channel 202 arranged in parallel. The first channel 201 and the second channel 202 respectively correspond to different water outlets of the faucet 200, and each water outlet is connected to the handle of the faucet 200 through a control circuit. The opening and closing of the handle of the faucet 200 transmits signals to the control circuit through a Hall element, and then the control circuit controls the on-off of each water path. This is the prior art and will not be elaborated too much here.

[0082] It can be understood that due to the need to clean food ingredients and the need to clean the second filter element 3 for bubble water, there are actually two flow paths for bubble water. Among them, the flow path of bubble water for cleaning food ingredients is in sequence: water source 100, upper filter element of the first filter element 5, first branch 10, booster pump 2, second branch 20, and the first channel 201 of the faucet 200. At this time, the first solenoid valve 6, the waste water solenoid valve 4, and the second channel 202 of the faucet 200 are correspondingly closed to ensure the flow rate of the bubble water.

[0083] And the flow path of bubble water for cleaning the second filter element 3 is in sequence: water source 100, upper filter element of the first filter element 5, first branch 10, second filter element 3, and waste water solenoid valve 4.

[0084] In this embodiment, as Figure 4As shown in the figure, the water circuit structure of the water purifier further includes a third branch 30. One end of the third branch 30 is connected to the main water circuit 1, and the other end of the third branch 30 is connected to the first channel 201. The third branch 30 is arranged in parallel with the second branch 20. A one-way valve 11 and a valve core 12 are arranged on the third branch 30. When the second branch 20 supplies sparkling water to the first channel 201, the opening degree of the valve core 12 is adjusted to regulate the flow rate entering the first channel 201.

[0085] Specifically, the first channel 201 is supplied with sparkling water through the third branch 30 and the second branch 20. Micro-nano bubble water is generated through the second branch 20, and the flow rate of the sparkling water entering the first channel 201 is regulated through the third branch 30. The valve core 12 is a mechanical valve core, and the one-way valve 11 is a structure in the prior art. When the third branch 30 is disconnected by the valve core 12 and the first branch 10 is connected to the second branch 20, micro-nano bubble water can flow through the first channel 201. At this time, the valve core 12 is rotated to open the third branch 30, so that the water flow without bubbles passing through the one-way valve 11 can be mixed with the micro-nano bubble water flowing out of the second branch 20 in a parallel connection manner when entering the first channel 201, and then sparkling water with an increased flow rate and a reduced bubble concentration can be obtained at the faucet 200 to meet the different water use requirements of users and improve the user experience.

[0086] In this embodiment, the water circuit structure of the water purifier further includes a fourth solenoid valve 13. The fourth solenoid valve 13 is located between the wastewater solenoid valve 4 and the wastewater outlet. When sparkling water or wastewater is discharged from the wastewater outlet, the fourth solenoid valve 13 closes the wastewater outlet.

[0087] Specifically, the wastewater solenoid valve 4 is used to discharge wastewater or sparkling water after being used for cleaning the second filter element 3. Since the wastewater solenoid valve 4 is set to only have a semi-open state and a fully open state in order to ensure the timely discharge of wastewater and used sparkling water, this will cause the water circuit structure to be in a pressure relief state all the time when the faucet 200 is closed, that is, the initial pressure inside the water circuit structure is small. When the faucet 200 is opened again within 3 to 5 seconds under the condition of small pressure, the water flow rate of the faucet 200 is affected by the pressure relief state and the water flow is small. By setting the fourth solenoid valve 13, the wastewater outlet is closed after the wastewater solenoid valve 4 discharges wastewater or used sparkling water, so that the pressure inside the water circuit structure rises, and then the water flow rate is increased when the faucet 200 is opened again. It can be understood that when the fourth solenoid valve 13 closes the wastewater outlet, the first solenoid valve 6 is opened to replenish water into the second filter element 3, which can improve the response time when the faucet 200 is opened again and further avoid the situation of small initial water flow rate of the faucet 200.

[0088] In this embodiment, when the second channel 202 of the faucet 200 is closed after pure water is generated in the main water path 1, the first solenoid valve 6 and the wastewater solenoid valve 4 are opened, the first branch 10 and the second branch 20 are closed, and the fourth solenoid valve 13 is opened for 3 s to allow the water flow in the water source 100 to flow into the second filter element 3, so as to discharge the wastewater in the second filter element 3 by the push of the water flow. When the water flow enters the second filter element 3, it can wash the second filter element 3. By supplementing the water flow, the TDS concentration in the second filter element 3 can be reduced, preventing the TDS of the first glass of water from being too high when the user draws water. Correspondingly, the method of washing the second filter element 3 with water flow also has the function of extending the service life of the second filter element 3.

[0089] In this embodiment, a jet injector 14 is provided on the first branch 10. The air inlet of the jet injector 14 is opened or closed by the second solenoid valve 15. When the second solenoid valve 15 is opened, bubble water is generated in the first branch 10.

[0090] Specifically, the water inlet end and the water outlet end of the first branch 10 are connected in parallel with the main water path 1. The jet injector 14 is connected in series between the water inlet end and the water outlet end of the first branch 10. The jet injector 14 has an air inlet to introduce external air into the interior of the jet injector 14 and mix it with the water flow inside the jet injector 14 to generate bubble water. A second solenoid valve 15 and a check valve 11 are provided between the air inlet of the jet injector 14 and the body of the jet injector 14. The check valve 11 is used to prevent the water flow inside the jet injector 14 from flowing out through the air inlet. The second solenoid valve 15 is provided to close the air inlet of the jet injector 14 when bubble water is not needed. When the second solenoid valve 15 closes the air inlet, bubble water cannot be generated in the first branch 10. Since the main water path 1 is connected in parallel with the first branch 10, the main water path 1 can normally pass water and generate pure water. The first solenoid valve 6 and the second solenoid valve 15 are controlled by a control circuit to realize the switching state between pure water and bubble water, so that the user can timely close the first branch 10 when pure water is needed for drinking, preventing the water from containing bubbles during drinking and affecting the user's drinking experience.

[0091] In addition, a pressure reducing valve 16 is further included on the first branch 10 in this embodiment. The pressure reducing valve 16 is provided between the water source 100 and the jet injector 14. The pressure reducing valve 16 is a pressure reducing structure in the prior art. By providing the pressure reducing valve 16, the water pressure at the water inlet end of the jet injector 14 can be reduced to avoid the influence on the generation efficiency of bubble water when the water pressure is too high.

[0092] As Figure 5 、 Figure 6 and Figure 7 shown, this embodiment also provides a combined water purifier and washer 300, and the combined water purifier and washer 300 includes the above-mentioned water purification machine water path structure.

[0093] Specifically, the integrated water purifying and washing machine 300 can produce pure water for drinking and can also produce sparkling water for washing food materials in addition to pure water. It has a higher degree of integration. By using the water circuit structure of this water purifier, the way of switching between producing pure water and sparkling water can be realized, enabling users to make independent choices and improving efficiency. In addition, the integrated water purifying and washing machine 300 includes the above-mentioned water circuit structure of the water purifier, so that the remaining sparkling water in the main water circuit 1 after the user has used the sparkling water can be used to rinse the filter element, thereby increasing the service life of the filter element, extending its replacement cycle, and reducing the user's usage cost.

[0094] In this embodiment, the integrated water purifying and washing machine 300 includes a bracket 301, a water circuit board 302, a booster pump assembly 303, a main control board 304, and a water tank assembly 305 that are connected in sequence. The water circuit board 302 and the water tank assembly 305 are disposed on opposite sides of the bracket 301. The booster pump assembly 303 is located below the water tank assembly 305, and the main control board 304 is located at the top of the bracket 301 and on the side away from the water tank assembly 305.

[0095] Specifically, the bracket 301 is disposed inside the integrated water purifying and washing machine 300. The bracket 301 includes vertical beams disposed along the vertical direction and cross beams disposed along the horizontal direction. There are two cross beams and two vertical beams, and they are connected in sequence. One vertical beam is connected to the ends of the two cross beams, and the other vertical beam is connected to the edge regions of the two cross beams to form a receiving area for accommodating the water tank assembly 305 and a receiving groove for accommodating the water circuit board 302. The water circuit structure of the water purifier is integrally disposed on the water circuit board 302, streamlining the external water circuit, reducing the installation difficulty and the risk of water leakage. The receiving area and the receiving groove are located on the opposite sides of the vertical beam disposed close to the edge of the cross beam, so that the water tank assembly 305 is located between the two relatively disposed vertical beams. The booster pump assembly 303 is disposed below the water tank assembly 305 and between the two vertical beams, improving the structural stability of the water tank assembly 305 and the booster pump assembly 303. The above structures are supported by the bracket 301, so that the internal structure of the integrated water purifying and washing machine 300 is reasonably arranged, reducing the space occupied by the integrated water purifying and washing machine 300 and having a higher degree of integration. In addition, the main control board 304 is disposed on the cross beam at the top of the water tank assembly 305 and on the surface of the cross beam on the side away from the water tank assembly 305. The main control board 304 is used to be electrically connected to the control circuit to realize the various functions of the water circuit structure of the water purifier. By setting the height of the main control board 304 higher than that of the water tank assembly 305, it is possible to prevent the electrically related parts of the integrated water purifying and washing machine 300 from failing when the water tank assembly 305 leaks, improving the usage safety.

[0096] In other embodiments, a baffle can also be provided at the edge of the cross beam for carrying the main control board 304 to further improve the waterproof ability of the main control board 304. This is prior art and will not be elaborated here.

[0097] Such as Figure 8 and Figure 9As shown, in this embodiment, the integrated cleaning machine 300 further includes a buffer member 306. The booster pump assembly 303 includes a booster pump 2 and a housing 17. The housing 17 covers the outer peripheral side of the booster pump 2, and the buffer member 306 is disposed between the surface of the housing 17 and the booster pump 2.

[0098] Specifically, the housing 17 is a split structure, including a first housing and a second housing. The first housing and the second housing are connected by bolts. The housing 17 is provided with a connecting portion connected to the bracket 301, and the connecting portion and the bracket 301 are connected by bolts. The buffer member 306 is disposed inside the housing 17 and contacts the end and the middle region of the booster pump 2 to reduce the vibration of the booster pump 2 during operation from being transmitted outward through the housing 17, prevent other connecting structures from resonating with the booster pump 2, and at the same time reduce the noise generated by the booster pump 2 during operation.

[0099] In this embodiment, the buffer member 306 is also disposed at the connection between the housing 17 and the bracket 301.

[0100] Specifically, the connecting portion on the housing 17 and the bracket 301 are connected by bolts, and a buffer member 306 is disposed between the connecting portion and the bracket 301 to reduce the transmission of the vibration of the housing 17 to the bracket 301, thereby reducing the noise during the use of the integrated cleaning machine 300. The buffer member 306 is made of silica gel material or nylon material used to reduce vibration in the prior art, etc., and will not be elaborated here.

[0101] As Figure 10 shown, an axially variable diameter region is provided inside the ejector 14 in this embodiment. Using the principle of a Venturi tube, when water flows through the axially variable diameter region, negative pressure is generated to suck in external air. Then, when the water and air are mixed to form a water-air mixture and ejected from the ejection port, high-frequency pressure fluctuations and high-speed and strong shear forces will be generated to shear the gas into bubbles. The axially variable diameter region includes a flow-limiting structure and a jet structure. The flow-limiting structure is provided with micropores. When water passes through the micropores, the flow rate increases and negative pressure is generated. There is a gap between the flow-limiting structure and the jet structure to suck in air under a negative pressure environment. The water-air mixture is mixed and sheared inside the horn-shaped ejection port of the ejector 14 and finally forms bubble water with cleaning ability. This is the prior art and will not be elaborated here.

[0102] In this embodiment, the size of the gas mixing chamber 7 is larger than the size of the pipeline, so that after the bubble water enters the gas mixing chamber 7, the bubbles and the water flow can be fully mixed, enhancing the cleaning ability of the bubble water.

[0103] Although the specific embodiments of the present invention have been described above, those skilled in the art should understand that this is only an example, and the protection scope of the present invention is defined by the appended claims. Without departing from the principles and essence of the present invention, those skilled in the art can make various changes or modifications to these embodiments, but these changes and modifications all fall within the protection scope of the present invention.
