Description of the embodiments
The present invention will be described in further detail with reference to the accompanying drawings.
Example 1
Referring to fig. 1 and 2, a water dispenser with water quality detection includes a body 12, a source water end 1 and a water outlet end 2 which are arranged on the body 12, a water treatment channel 3 for water inlet and outlet and treatment, a first detection branch 4, a second detection branch 5, and a detection module 7 for water quality detection.
The source water end 1 is a water tank for storing water, and the water outlet end 2 is a water outlet. In other embodiments, the source water end 1 comprises a water tank for storing water, a pipeline for communicating the water tank and the water treatment channel 3; the water outlet end 2 comprises a pipeline for the water outlet nozzle and communicating the water outlet nozzle with the water treatment channel 3.
In this embodiment, the upstream of the water treatment channel 3 communicates with the source water end 1, and the downstream of the water treatment channel 3 communicates with the water storage end. The upstream of the first detection branch 4 is communicated with the source water end 1, while the downstream of the first detection branch 4 is communicated with the detection module 7. The upstream of the second detection branch 5 communicates with the water outlet end 2, while the downstream of the second detection branch 5 communicates with the detection module 7 described above.
The body 12 is provided with a display component for displaying the detection value of the detection module 7.
When the water quality of the source water end 1 is detected, the first detection branch 4 is conducted, the second detection branch 5 is closed, water of the source water end 1 flows into the detection module 7 through the first detection branch 4, and the display component displays the detection value of the water quality of the source water end 1.
When the water quality of the water outlet end 2 is detected, the second detection branch 5 is conducted, the first detection branch 4 is closed, water of the water outlet end 2 flows into the same detection module 7 through the second detection branch 5, and the display component displays the detection value of the water quality of the water outlet end 2.
The water quality of the source water end 1 and the water outlet end 2 is displayed through the display component, a user can observe the change of the water quality after passing through the water treatment channel 3, and whether the water treatment channel 3 works normally is judged.
When water quality detection is needed, the first detection branch 4 and the second detection branch 5 are sequentially conducted, and when the water quality detection of the source water end 1 is unqualified, water outlet work is stopped, water quality detection is not needed to be carried out on the water outlet end 2, and the improvement of work efficiency is facilitated.
The same detection module 7 is used for detecting the water quality of the source water end 1 and the water quality of the water outlet end 2, and is beneficial to reducing the cost of the detection module 7. In addition, during water quality detection, the first detection branch 4 and the second detection branch 5 are used for conducting drainage to the detection module 7 for detection, so that interference of water quality detection on normal water outlet of the water treatment channel 3 is avoided. In addition, in the operating condition that does not need water quality testing, first detection branch circuit 4 and second detection branch circuit 5 can close, and detection module 7 is inoperative, is favorable to reducing detection module 7 loss, reduces detection module 7 life's waste promptly.
Specifically, the body 12 is provided with a backflow channel 6, and the backflow channel 6 is communicated with the source water end 1 and the detection module 7. The detection water flowing into the detection module 7 flows back to the source water end 1 through the backflow channel 6, so that the waste of the drinking water can be reduced. Because the same detection module 7 detects the water quality of the source water end 1 and the water outlet end 2, both the two detections are performed with backflow through the same backflow channel 6. Since the return channel 6 is downstream of the detection module 7, the residual water in the return channel 6 does not affect the next detection.
The detection module 7 is in one-way conduction, and water of the first detection branch 4 and the second detection branch 5 flows into the detection module 7 from the same end of the detection module 7 and then flows back to the source water end 1 through the backflow channel 6.
The detection elements of the detection module 7 may be arranged on a single side compared to the bi-directional conduction of the detection module 7. Whether the first detection branch 4 is conducted or the second detection branch 5 is conducted, the water quality in the same flow direction is detected by the detection module 7, so that the detection difficulty is reduced, and the accuracy of the detection value is improved.
In particular, the first detection branch 4 and the second detection branch 5 have a common detection section 8, the downstream of the detection section 8 being in communication with the detection module 7. The detection section 8 is located at the inlet of the detection module 7 and belongs to both the first detection branch 4 and the second detection branch 5. Although the first detecting branch 4 and the second detecting branch 5 cannot be simultaneously conducted, the lengths of the first detecting branch 4 and the second detecting branch 5 can be reduced by the common detecting section 8, and thus the pipeline cost of the first detecting branch 4 and the second detecting branch 5 can be reduced.
In other embodiments, the same end of the detection module 7 has two water inlets, which are respectively connected to the first detection branch 4 and the second detection branch 5. The first detection branch 4 and the second detection branch 5 are not overlapped, so that the influence of residual water of the first detection branch 4 on the water quality of the second detection branch 5 can be avoided, and the accuracy of water quality detection is improved.
In other embodiments, the body 12 is provided with a waste water channel 9, and the waste water channel 9 is communicated with the detection module 7 upstream. The detection water of the detection module 7 is discharged to the outside of the body 12 or the waste water box of the body 12 through the waste water channel 9.
In this embodiment, a filter assembly is provided on the water treatment channel 3. The user can judge whether filtration efficiency of filter element and filter core need be changed according to the detected value of source water end 1 and play water end 2. In other embodiments, a heating assembly and a filtering assembly are provided on the water treatment channel 3.
In this embodiment, the source water end 1 is provided with a first water valve 10, and the first water valve 10 controls the source water end 1 to be selectively connected with the water treatment channel 3, and the first detection branch 4 is connected.
When detecting the water quality of the source water end 1, the first water valve 10 controls the source water end 1 to be communicated with the first detection branch 4, and the source water end 1 is disconnected with the water treatment channel 3, so that the water quality detection is prevented from being interfered by the water outlet of the water treatment channel 3.
In other embodiments, the source water end 1 is provided with the first water valve 10, and the first water valve 10 can control the source water end 1 to be simultaneously conducted with the water treatment channel 3 and the first detection branch 4, so that the efficiency of water discharge and detection at the same time and the efficiency of handle detection and water discharge are realized. If the detected water quality is unqualified, stopping the water outlet of the water treatment channel 3.
In this embodiment, the water outlet end 2 is provided with a second water valve 11, and the second water valve 11 controls the water outlet end 2 to conduct water and the water outlet end 2 to conduct with the second detection branch 5.
When the water quality of the water outlet end 2 is detected, the water outlet end 2 stops discharging, and the second water valve 11 controls the water outlet end 2 to be communicated with the second detection branch 5. Detecting the water quality of the water outlet end 2, and if the detected water quality is unqualified, the water outlet end 2 does not outlet water; if the detected water quality is qualified, the water outlet end 2 outputs water, and the water outlet end 2 is disconnected with the second detection branch 5.
In other embodiments, when the water quality of the water outlet end 2 is detected, the water outlet end 2 is discharged, and the second water valve 11 controls the water outlet end 2 to be communicated with the second detection branch 5, so that water outlet and water quality detection are performed simultaneously.
In this embodiment, the first detection branch 4, the water treatment channel 3, and the second detection branch 5 are sequentially turned on, so that the water dispenser can detect the water quality of the source water end 1, then the water outlet works, and finally the water quality of the water outlet end 2 is detected. Compared with the water treatment channel 3, the first detection branch 4 and the second detection branch 5 are sequentially conducted, whether the water quality of the source water end 1 is qualified or not can be timely found, and the possibility that unqualified water is discharged from the water outlet end 2 is reduced.
Example two
Referring to fig. 3, 4 and 5, a water dispenser with water quality detection includes a body 12, a water storage member 13 disposed on the body 12, a water inlet pipe 14, a water treatment device 19, a water outlet pipeline 15, and a first detection passage 16. Wherein the water storage member 13 is a water tank or a water bottle.
The water inlet pipe 14 communicates with the water storage member 13 and the water treatment device 19 for transporting water of the water storage member 13 to the water treatment device 19. The water outlet pipeline 15 is communicated with the water treatment device 19 and is used for discharging water of the water treatment device 19 out of the machine body 12. The body 12 is provided with a first detection passage 16, and the first detection passage 16 is provided with a first detection module 161 for detecting water quality. When water quality needs to be detected, the first detection passage 16 is communicated with the water storage piece 13, and the detected water of the first detection passage 16 flows back into the water storage piece 13 through the first detection module 161, so that waste of the detected water is reduced. Meanwhile, under the condition that water quality detection is not needed, the first detection passage 16 can be closed, and the water dispenser can normally discharge water, so that damage to the first detection module 161 is reduced, and the service life of the first detection module 161 is saved.
In this embodiment, the upstream of the first detection passage 16 is directly connected to the water outlet line 15. When the water quality of the water outlet pipe is detected, the water outlet pipe 15 stops water outlet and is communicated with the first detection passage 16; the water in the water outlet pipeline 15 flows back into the water storage piece 13 through the first detection passage 16, and the first detection module 161 detects the water quality condition of the water outlet pipeline 15.
Specifically, the first detection module 161 is turned on in two directions, and when the quality of the water in the water storage part 13 is detected, the machine body 12 stops water outlet work, so that the water pressure of the water outlet pipeline 15 is prevented from entering the first detection passage 16; then the first detection passage 16 is opened, water in the water storage member 13 flows into the first detection passage 16 under the action of gravity, and the first detection module 161 detects the water quality of the water storage member 13. The water quality detection of the water storage part 13, the water quality detection of the water outlet pipeline 15 and the backflow of the detection water can be realized through one passage, so that the detection cost is saved. In addition, when detecting water quality of the water storage piece 13, a water pump is not needed to provide water pressure, so that energy loss is reduced.
In other embodiments, the body 12 is provided with a waste water box 18, a second detection passage 17 is provided between the waste water box 18 and the water inlet pipe 14, and a second detection module 171 for detecting water quality is provided on the second detection passage 17. When the water quality of the water inlet pipe 14 is detected, water flows out from the water outlet pipe, flows into the waste water box 18 through the second detection passage 17. The water quality detection of the inlet water and the outlet water is divided into two detection channels, so that the mutual interference between the water quality detection of the inlet pipe 14 and the water quality detection of the outlet pipe 15 can be avoided.
In other embodiments, the body 12 is provided with a waste water box 18, the waste water box 18 is communicated with the water inlet pipe 14, and the waste water box 18 is provided with a second detection module 171 for detecting water quality. When the water quality of the water inlet pipe 14 is detected, the water inlet pipe 14 directly discharges water to the waste water box 18 for detection. The detection water is collected in the waste water box 18, and the second detection module 171 can detect and obtain the average value of turbidity at the waste water box 18.
In other embodiments, the first detection passage 16 is directly connected to the water inlet pipe 14, and when the water quality of the water inlet pipe 14 is detected, the water inlet pipe 14 is disconnected from the water treatment device 19, the water in the water inlet pipe 14 flows back into the water storage member 13 through the first detection passage, and the turbidity of the water inlet pipe 14 is detected by the first detection module 161. The water quality does not pass through the water treatment device 19 and flows back into the water storage piece 13 from the water inlet pipe 14, the water quality of the water storage piece 13 is not affected, and the water quality in the water storage piece 13 is not changed.
Specifically, the water outlet pipeline 15 is directly communicated with a second detection passage 17, the machine body 12 is provided with a waste water box 18, and the waste water box 18 is communicated with the second detection passage 17. The second detection passage 17 is provided with a second detection module 171 for water quality detection.
When the water quality of the water outlet pipeline 15 is detected, the water pump on the machine body 12 presses water from the water inlet pipe 14 to the water outlet pipeline 15, but the water outlet pipeline 15 is not conducted, and water cannot be discharged; at the same time, the second detection passage 17 is communicated with the water outlet pipeline 15, and water in the water outlet pipeline 15 flows into the waste water box 18 through the second detection passage 17. The water flowing to the water outlet pipe 15 passes through the water treatment device 19, and the water treatment device 19 may work to deteriorate the water quality. Compared with the backflow of the detection water of the water outlet pipeline 15, when the water quality of the water outlet pipeline 15 is detected, the detection water is directly discharged to the waste water box 18, and the water of the water storage part 13 and the water inlet pipe 14 can be prevented from being polluted by the water of the water outlet pipeline 15.
Specifically, the water treatment device 19 is a heating element 191. The water from the outlet pipe is heated by the heating element 191 and enters the outlet pipe 15, and the water from the outlet pipe 15 is hot water and may have scale. When the water quality of the water outlet pipeline 15 is detected, the detection water is discharged to the waste water box 18, so that the influence on drinking water health caused by the fact that the hot water of the water outlet pipeline 15 is mixed with the cold water of the water storage part 13 to form yin and yang water can be avoided. In addition, if the water in the water outlet pipeline 15 has scale, the scale can be timely found when being discharged into the waste water box 18, and the scale is prevented from flowing back into the water storage part 13.
In other embodiments, the second detection module 171 is disposed on the water outlet pipe 15, and when the water outlet pipe 15 is discharging water, the second detection module 171 can perform water quality detection to obtain turbidity of the discharged water. Therefore, the water outlet and water quality detection of the water outlet pipeline 15 can be performed simultaneously, which is beneficial to improving the working efficiency.
In another embodiment, the water treatment device 19 is a filter unit 192, the first detection passage 16 is used for detecting the water quality of the water outlet pipe, and the body 12 is provided with the second detection passage 17 for detecting the water quality of the water pipe 15.
The water quality of the water inlet pipe 14 is detected by the first detection passage 16, and the water quality of the water outlet pipe 15 is detected by the second detection passage 17. The user can interpret whether the filter assembly 192 has failed based on the two sensed values and replace it in time.
In the water quality test in this embodiment, turbidity of water or organic carbon content is measured, and a measured value is obtained by absorbing infrared rays or ultraviolet rays by liquid.
The foregoing is merely exemplary embodiments of the present invention and is not intended to limit the scope of the invention, which is defined by the appended claims.
