The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0035] like Figure 1 As shown, a water purifier according to an embodiment of the present invention includes a purified water tank 200, a cold water tank 212, a flow pump 213, a drive pump 221, and a heating element 222. The inlet of the cold water tank 212 is connected to the outlet of the purified water tank 200; the inlet of the flow pump 213 is connected to the outlet of the cold water tank 212, and the outlet of the flow pump 213 is connected to the cold water outlet 214; the inlet of the drive pump 221 is connected to the outlet of the purified water tank 200; the inlet of the heating element 222 is connected to the outlet of the drive pump 221, and the outlet of the heating element 222 is connected to the hot / room temperature water outlet 224.

[0036] like Figures 4 to 7 As shown, the water purifier also includes a raw water tank 100, a booster pump 111, a filter element 112, and a flushing solenoid valve 121. The inlet of the booster pump 111 is connected to the outlet of the raw water tank 100, and the outlet of the booster pump 111 is connected to the inlet of the filter element 112. The outlet of the filter element 112 is connected to the inlet of the purified water tank 200. The inlet of the flushing solenoid valve 121 is connected to the concentrated water outlet of the filter element 112, and the outlet of the flushing solenoid valve 121 is connected to the return port of the raw water tank 100.

[0037] Further, the filtering component 112 comprises a polypropylene activated carbon composite filter core 113, a reverse osmosis membrane filter core 114, and an activated carbon water purification composite filter core 115. The raw water in the raw water tank 100 is filtered by the polypropylene activated carbon composite filter core 113, the reverse osmosis membrane filter core 114, and the activated carbon water purification composite filter core 115 in sequence under the action of the booster pump 111, and the filtered purified water is delivered to the purified water tank 200. Moreover, the concentrated water filtered by the reverse osmosis membrane filter core 114 is sequentially guided through the concentrated water outlet of the filtering component 112, the flushing electromagnetic valve 121, and the backflow outlet of the raw water tank 100, and finally returns to the raw water tank 100.

[0038] With reference to the drawings, the purified water machine comprises a raw water tank 100, a booster pump 111, a filtering component 112, a purified water tank 200, and a flushing electromagnetic valve 121. Figure 4 Figure 5 The purified water machine further comprises a second flow meter 116 arranged between the raw water tank 100 and the booster pump 111 or between the booster pump 111 and the filtering component 112, for cumulatively calculating the pumping amount of the booster pump 111.

[0039] With reference to the drawings, the purified water machine comprises a raw water tank 100, a booster pump 111, a filtering component 112, a purified water tank 200, and a flushing electromagnetic valve 121. Figure 4 Figure 6 The purified water machine further comprises a third flow meter 122 arranged between the raw water tank 100 and the flushing electromagnetic valve 121 or between the flushing electromagnetic valve 121 and the filtering component 112, for cumulatively calculating the amount of concentrated water remaining after being filtered by the reverse osmosis membrane filter core 114.

[0040] In the embodiment, the water production amount of the purified water machine can be obtained by subtracting the amount of concentrated water remaining after being filtered by the reverse osmosis membrane filter core 114 from the pumping amount of the booster pump 111. According to the calculated water production amount, the service life of the reverse osmosis membrane filter core 114 can be determined in combination with the TDS value, and the determination result is more accurate. When the water production amount is less than the normal range, the service life of the reverse osmosis membrane filter core 114 can be determined in combination with the TDS value, and a new reverse osmosis membrane filter core 114 needs to be replaced.

[0041] Further, when the purified water machine is operated to produce water, the signals fed back by the second flow meter 116 and the third flow meter 122 received by the processor can assist in determining whether the purified water machine has a problem.

[0042] When there is no signal feedback from the second flow meter 116 or the third flow meter 122, it can be determined that the components in the purified water machine are faulty or the filtering component 112 is blocked.

[0043] When the pumping amount of the booster pump 111 fed back by the second flow meter 116 or the amount of concentrated water remaining after being filtered by the reverse osmosis membrane filter core 114 fed back by the third flow meter 122 is much less than the normal case, it can be determined that the filtering component 112 is blocked.

[0044] ​​When the water pumping amount of the booster pump 111 fed back by the second flow meter 116 is small, and the third flow meter 122 has no signal feedback, it can be judged that the flushing electromagnetic valve 121 or the filter component 112 is blocked.

[0045] When the water pumping amount of the booster pump 111 fed back by the second flow meter 116 is normal, and the water amount of the concentrated water left after the reverse osmosis membrane filter core 114 filtering fed back by the third flow meter 122 is too large, it can be judged that the flushing electromagnetic valve 121 is faulty and in an open state.

[0046] Referring again to Figure 4 and Figure 6 , the second flow meter 116 is arranged between the raw water tank 100 and the booster pump 111, and is used to detect whether there is raw water in the raw water tank 100. The raw water tank 100 is provided with a water guide pipe 101, which is in communication with the raw water tank 100. The raw water in the upper layer of the raw water tank 100 flows out of the water guide pipe 101. The second flow meter 116 is arranged between the raw water tank 100 and the booster pump 111, and when the liquid level of the raw water in the raw water tank 100 is lower than the water guide pipe 101, no water flows through the second flow meter 116, at this time, the second flow meter 116 has no signal feedback, the booster pump 111 stops running, and it is prompted to replace the raw water, so as to avoid the booster pump 111 from being empty and gas-stuck.

[0047] Further referring to Figure 8 , the above-mentioned raw water tank 100 can also be selected to have two cavities on the left and right sides, so as to completely separate the raw water and the concentrated water, and the second flow meter 116 can also be used to detect that the raw water is used up and prompt the replacement of the raw water.

[0048] Further referring to Figure 1 , in the embodiment, the flow pump 213 is used to pump out the cold water in the cold water tank 212 and deliver the cold water to the cold water outlet 214; and the flow pump 213 is preferably a diaphragm pump with a flow meter, which is electrically connected with the processor, and is used to detect whether there is cold water flowing through the flow pump 213, and can also be used to detect the water amount of each time of taking cold water operation, so that the processor determines the water amount left in the cold water tank 212 according to the water amount. When the flow pump 213 detects that there is no water flowing through the flow pump 213, the processor determines that there is no water in the cold water tank 212, and the processor controls the flow pump 213 to stop running. In other embodiments of the present application, the flow pump 213 can also include a diaphragm pump and a flow meter, and the diaphragm pump and the flow meter are separate elements.

[0049] The water inlet of the cold water tank 212 is provided with a water drain valve 211, and the water injection speed of the water drain valve 211 is less than the water taking speed of the flow pump 213. Specifically, the water inlet of the water drain valve 211 is in communication with the water outlet of the clean water tank 200, and the water outlet of the water drain valve 211 is in communication with the water inlet of the cold water tank 212.

[0050] When the user starts the cold water taking operation, the flow pump 213 starts to pump the cold water in the cold water tank 212 to the cold water outlet 214. During the cold water taking, the water in the purified water tank 200 is continuously injected into the cold water tank 212 through the water outlet valve 211. However, since the injection speed of the water outlet valve 211 is less than the water taking speed of the flow pump 213, when the user continuously takes cold water and the cold water in the cold water tank 212 is taken out, there is no cold water passing through the flow pump 213, i.e. the flow pump 213 cannot detect the water flow signal, so that the processor in the purified water machine determines that the internal water level of the cold water tank 212 is empty, and controls the flow pump 213 to stop the water taking operation. After that, the user can be prevented from taking ice water by disabling the ice water taking button and the like. After the flow pump 213 stops operating for more than a preset time, the user can be allowed to continue to take cold water by enabling the ice water taking button and the like.

[0051] As shown in Figure 2 and Figure 3 In the embodiment, the drive pump 221 includes a first flow meter 225 and a water pump 226, and the first flow meter 225 is arranged between the purified water tank 200 and the water pump 226 or between the water pump 226 and the heating pipe 222. The water pump 226 is used to pump the water in the purified water tank 200 to the heating pipe 222, and the first flow meter 225 is used to detect whether there is water in the purified water tank 200.

[0052] When the user takes hot water, when the first flow meter 225 has no signal feedback, it is determined that the internal water level of the purified water tank 200 is empty, the purified water machine system stops the water taking operation, and the dry pumping phenomenon is prevented. The heating pipe 222 is controlled to stop heating, so as to prevent the user from being scalded and the heating pipe 222 from being burned out and unable to be used due to dry burning.

[0053] In the embodiment, the drive pump 221 is selected as a diaphragm pump with a flow meter, which can also achieve the effect of preventing the user from being scalded and the heating pipe 222 from being burned out and unable to be used due to dry burning.

[0054] In order to ensure that the air pressure of the water path of the purified water machine is stable during use, the purified water machine further includes a first exhaust pipe 201 and a second exhaust pipe 202. The exhaust port of the cold water tank 212 is communicated with the purified water tank 200 through the first exhaust pipe 201, and the hot water / normal temperature water outlet 224 is communicated with the purified water tank 200 through the second exhaust pipe 202.

[0055] The utility model discloses a water purifier, in the water taking process, the water flow is monitored accurately, realizes the control to cold water tank 212 water supply and heating pipe 222 water supply, has met the demand of user to refrigerated water and hot water again, has promoted the performance and reliability of whole water supply system. Through using the flow pump 213 that can monitor water flow, and cooperate with using the water release valve 211 of water injection speed less than flow pump pumping speed, the water supply of cold water tank 212 is controlled accurately, realizes the intelligent management to cold water supply, promotes user experience, avoids the waste of water resources and the unnecessary operation loss of equipment simultaneously. Through using the signal accumulation of second flowmeter 116 and third flowmeter 122 calculates the water production, can more accurately obtain the service life of filter part 112. And through the signal feedback of second flowmeter 116, prompt raw water tank 100 has reached the water level of raw water replacement, and the booster pump 111 stops water production, and the raw water replacement is prompted, avoids the booster pump 111 empty pumping and gas trouble.

[0056] The above-mentioned embodiments only express several implementation manners of the utility model, and the description is more specific and detailed, but it can not be understood as the limitation of the utility model patent scope. It should be pointed out that for ordinary skilled person in the art, without departing from the concept of the utility model, a number of modifications and improvements can be made, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be the appended claims.
