Referring to fig. 1, the present embodiment provides a waterway protection system applied to a dishwasher. The water path protection system comprises a liner 1, a water inlet valve assembly (not shown in the figure), an overflow transmission mechanism 3, an overflow detection module (not shown in the figure), a water inlet flow meter 5 and a control module (not shown in the figure), wherein the liner 1 is provided with a water inlet, an overflow port 101, a water inlet pipe 11, an overflow pipe 12 and a water cup 13, the water inlet end of the water inlet pipe 11 is communicated with a water source, the water outlet end is communicated with the water inlet through the water cup 13, the water cup 13 is arranged at the bottom of the liner 1 and is communicated with the liner 1, and therefore the water outlet end of the water inlet pipe 11 is communicated with the inside of the liner 1. The inlet of the overflow pipe 12 is connected to the inside of the inner container 1 through the overflow port 101, and the outlet of the overflow pipe 12 is connected to a water collecting part (not shown), which may be a drain port of a dishwasher, a sewer, or a water storage tank in this embodiment.
The water inlet valve assembly at least comprises a first water valve 21 and a second water valve 22 electrically connected with the control module, and the first water valve 21 and the second water valve 22 are both arranged on the water inlet pipe 11 and are both used for controlling the on-off of the water inlet pipe 11. The overflow transmission mechanism 3 is arranged on the overflow pipe 12 and is linked with the valve core of the first water valve 21. The first water valve 21 of the present embodiment is preferably a mechanical valve, the opening of which is achieved by a manual operation of a user, and the closing of which is achieved by a manual operation of a user or a linkage of the overflow transmission mechanism 3. The second water valve 22 is preferably an electrically powered water inlet valve, such as a water inlet solenoid valve.
The overflow detection module is arranged on the overflow pipe 12 or the overflow transmission mechanism 3, and is electrically connected with the control module and used for detecting the overflow water quantity of the inner container 1. The water inlet flow meter 5 is arranged on the water inlet pipe 11 and is positioned at the water outlet rear end of the first water valve 21, and the water inlet flow meter 5 is electrically connected with the control module and is used for detecting the water inlet flow of the water inlet pipe 11.
When the inner container 1 needs to be filled with water, the first water valve 21 is manually opened and the second water valve 22 is automatically opened, so that water flows into the water cup 13 through the water inlet pipe 11. When the water inlet flow meter 5 is in fault, or when the water inlet flow meter 5 is normal and detects that the water inlet flow reaches the set flow, and the second water valve 22 is in fault or fails to realize automatic control closing, at the moment, the water source can be continuously supplied to the water cup 13, and as the water quantity increases, water flows into the inner container 1 from the water cup 13, and the water level in the inner container 1 is lifted.
When the water level in the inner container 1 rises to the overflow port 101, the water in the inner container 1 flows out from the overflow port 101, that is, the inner container 1 overflows, and the overflow water flows down along the overflow pipe 12, passes through the overflow transmission mechanism 3, and finally flows into the water collecting part. In the process, the overflow detection module detects the overflow water amount, the overflow transmission mechanism 3 can move under the pushing of the overflow water to further drive the valve element of the first water valve 21 to move, so that the first water valve 21 is closed, the first water valve 21 is directly closed in a mechanical mode, the reliability is high, a water source is cut off in time, waste of water resources is avoided, and the condition of a customer is prevented from being soaked.
It can be seen that, in the waterway protection system of this embodiment, the first water valve 21 is disposed on the water inlet pipe 11, and the overflow transmission mechanism 3 linked with the first water valve 21 is additionally disposed on the overflow pipe 12, and the overflow transmission mechanism 3 can drive the valve element of the first water valve 21 to move under the pushing of the overflow water, so as to close the first water valve 21. In addition, in the water inlet process, whether the water inlet flow detected by the water inlet flow meter 5 reaches the set flow and whether the inner container 1 overflows or not can be accurately identified, so that the second water valve 22 or the water inlet flow meter 5 is in failure or invalid, and the after-sale maintenance is convenient.
Referring to fig. 2 to 4, in the present embodiment, the overflow transmission mechanism 3 includes a housing 31, an impeller 32 and a transmission shaft 33, the housing 31 has an overflow passage 311 through which overflow water passes, a water inlet end of the overflow passage 311 communicates with an outlet of the overflow pipe 12, and a water outlet end of the overflow passage 311 communicates with the water collecting portion. The impeller 32 is rotatably provided in the overflow passage 311, and the impeller 32 can be rotated by the push of the overflow water. One end of the transmission shaft 33 is connected to the center of the impeller 32, and the other end penetrates out of the housing 31 and is connected to the valve core of the first water valve 21. Therefore, the valve core of the first water valve 21 is reliably linked with the impeller 32 through the transmission shaft 33, and when the impeller 32 is pushed by overflow water to rotate, the valve core of the first water valve 21 can be reliably driven to move, so that the first water valve 21 is closed, the first water valve 21 is directly closed in a mechanical mode, and the reliability is high.
The overflow driving mechanism 3 further includes a driving assembly (not shown in the figures), the first water valve 21 has a valve rod 211 extending towards the driving shaft 33, one end of the valve rod 211 is connected to the valve core of the first water valve 21, and the other end is in driving connection with the driving shaft 33 through the driving assembly. Therefore, the transmission assembly, the valve rod 211 and the transmission shaft 33 are matched, so that the valve rod 211 and the transmission shaft 33 are stably and reliably connected while the transmission assembly is convenient to install, and further the valve core of the first water valve 21 is reliably linked with the impeller 32.
In this embodiment, the transmission assembly may include a driving wheel 34 and a driven wheel 35, the driving wheel 34 is disposed on the transmission shaft 33 and close to the valve rod 211, and the driven wheel 35 is disposed on the valve rod 211 and engaged with the driving wheel 34. Therefore, the valve rod 211 and the transmission shaft 33 are reliably connected in a gear transmission mode through the driving wheel 34 and the driven wheel 35 which are meshed with each other, and reliability is improved.
Optionally, the driving wheel 34 may be a large bevel gear, and the driven wheel 35 is a small bevel gear correspondingly, so that the large bevel gear drives the small bevel gear to rotate, thereby increasing the closing speed of the first water valve 21, shortening the response time for cutting off the water source, and being beneficial to reducing the waste of water resources. Of course, it is also possible to design the driving wheel 34 as a gearwheel, while the driven wheel 35 corresponds to a pinion.
In other embodiments, the driving assembly may further include a pulling member and a winding disc, the winding disc is connected to one end of the driving shaft 33 located outside the housing 31, and opposite ends of the pulling member are respectively connected to the winding disc and the valve rod 211. The winding disc can rotate with the impeller 32 to perform winding movement, and the winding disc can drive the valve rod 211 to move when winding so as to close the first water valve 21. When the first water valve 21 needs to be opened, the winding disc is controlled to be wound and unwound, and the valve core of the first water valve 21 is moved towards the opening direction, so that the first water valve 21 is opened.
Referring to fig. 2-3, the overflow detecting module is a signal collecting component (not shown in the figure), which is disposed on the housing 31 and electrically connected to the control module, and is used for collecting the number of rotation turns of the impeller 32 driven by the overflow water. Therefore, the overflow transmission mechanism 3 has the function of a flowmeter by counting the rotation turns of the impeller 32, and realizes real-time detection of the overflow water flowing through the impeller 32, thereby accurately detecting the overflow water of the inner container 1.
In this embodiment, the signal acquisition assembly includes a magnetic member (not shown in the drawings) and a sensing member 36 for sensing the magnetic member, the magnetic member is disposed on the impeller 32 and rotates with the impeller 32, and the sensing member 36 is disposed on the housing 31.
Referring to fig. 1, in the present embodiment, the inflow flowmeter 5 is disposed on the inflow pipe 11 and located at the outflow rear end of the second water valve 22, so that by disposing the inflow flowmeter 5 at the outflow rear end of the second water valve 22, the accuracy and reliability of the inflow detection result are further improved by virtue of the steady flow effect of the second water valve 22 on the inflow.
Referring to fig. 1, the present embodiment also provides a dishwasher having a waterway protection system as described above. Therefore, the overflow transmission mechanism 3 is driven to move through the overflow of the inner container 1, the overflow transmission mechanism 3 is linked with the second water valve 21, a water inlet source of the dish washing machine is closed, water resource waste and water overflow from the dish washing machine are avoided, and the condition of a bubble client home is prevented from being generated.
In addition, the overflow transmission mechanism 3 has an overflow water quantity detection function, and according to the inflow water quantity detected by the inflow water flowmeter 5 and the overflow water quantity detected by the overflow transmission mechanism 3, the control module can accurately identify whether the inflow water flowmeter 5 fails or the measurement is inaccurate, and also can accurately identify whether the second water valve 12 fails or fails, so that the after-sale maintenance is facilitated.
Example 2
Referring to fig. 5, the difference between the present embodiment and embodiment 1 is that the overflow detecting module is an overflow flowmeter 4, the overflow flowmeter 4 is mounted on the overflow pipe 12 and located at the water inlet front end of the overflow transmission mechanism 3, or the overflow flowmeter 4 is directly mounted on the water inlet end of the overflow transmission mechanism 3, that is, the overflow flowmeter 4 is directly mounted on the water inlet end of the overflow channel 311 for detecting the overflow water amount of the inner container 1. At this time, the signal acquisition assembly can be correspondingly omitted.
Therefore, the overflow detection module is separated from the overflow transmission mechanism 3, when the overflow flowmeter 4 is in fault or abnormal, the whole overflow transmission mechanism 3 does not need to be replaced, and only the corresponding overflow flowmeter 4 needs to be replaced, so that the later maintenance cost is reduced.
Referring to fig. 5, the present embodiment also provides a control method of a dishwasher, which applies the dishwasher as described above, the control method including the steps of:
s1, starting a washing program by the dishwasher;
s2, opening the first water valve 21 and the second water valve 22, and starting the overflow detection module and the water inlet flowmeter 5;
in particular, the first water valve 21 is a manually opened mechanical valve, which may be designed as a normally open valve, or manually opened by a user when it is desired to start a washing program. The second water valve 22 is a water inlet electromagnetic valve electrically connected with the control module, and the control module controls the second water valve 22 to be opened when receiving a washing program starting signal, so that the water inlet pipe 11 is in an open state, and water flows into the water cup 13 communicated with the inner container 1 from the water inlet pipe 11.
The water inlet flow meter 5 is started at the same time when the second water valve 22 is opened, and is used for detecting the water inlet flow of the water inlet pipe 11 in real time. The overflow detection module can be started synchronously with the water inlet flow meter 5, and can also be started after the water inlet flow meter 5 is started for a period of time, so that the workload of the overflow detection module is reduced. The overflow detection module continuously detects whether the overflow pipe 12 has overflow water, and detects the overflow water amount of the overflow pipe 12 in real time when the overflow water exists.
S3, continuously judging whether the water inlet flow reaches the set flow and whether the overflow water detection module detects the overflow water;
specifically, the control module determines whether the inflow water rate reaches a set value according to the inflow water rate detected by the inflow water meter 5. And the control module judges whether the inner container 1 overflows according to the detection result of the overflow detection module.
S31, if the inflow water rate does not reach the set flow rate and the overflow water rate is not detected by the overflow detection module, the step S3 is executed continuously;
and S32, if the inflow reaches the set flow and the overflow detection module does not detect the overflow flow, controlling the second water valve 22 to close.
Specifically, when the inflow reaches the set flow, it indicates that the inflow of the dishwasher reaches the set requirement, at this time, the second water valve 22 needs to be controlled to close, and the inflow of water is cut off in time, so that the waste of water resources caused by the excessive inflow of the dishwasher is avoided, and meanwhile, the effect of cleaning tableware by the dishwasher due to the excessive inflow is prevented from being influenced.
It should be noted that, although the inflow water flow rate detected by the inflow water meter 5 reaches the set flow rate, it is uncertain whether the measurement of the inflow water meter 5 is accurate at this time, that is, it is uncertain whether the inflow water meter 5 needs to be calibrated.
And S33, if the inflow water rate does not reach the set flow rate and the overflow water rate is detected by the overflow detection module, determining that the inflow water flowmeter 5 has a fault.
Specifically, the water inlet flow detected by the water inlet flow meter 5 does not reach the set flow all the time, but the overflow detection module detects that the inner container 1 overflows, which indicates that the water inlet flow meter 5 is faulty or invalid, and therefore, the water inlet flow meter 5 is determined to be faulty.
Due to the fault of the water inlet flow meter 5, the dishwasher cannot detect a signal that the water inlet flow reaches the set flow, and further cannot automatically control the second water valve 22 to be automatically closed, so that the water source is continuously supplied to the inner container 1, the water in the inner container 1 flows out of the overflow port 101, the overflow water flows downwards along the overflow pipe 12 and flows through the impeller 32 of the overflow transmission mechanism 3, the impeller 32 rotates under the push of the overflow water, and further drives the valve rod 211 of the first water valve 21 to move, so that the first water valve 21 is closed, and therefore the first water valve 21 is directly closed through a mechanical mode, the reliability is high, the water source is cut off in time, the waste of water resources is avoided, and the condition of a water bubble client is prevented.
It can be seen that, in the control method of the dishwasher of the embodiment, in the washing procedure, the fault of the water inlet flowmeter 5 can be accurately identified according to whether the water inlet flow reaches the set flow and whether the overflow water detection module detects the overflow water. In addition, when the inner container 1 of the dish washing machine overflows, the pushing action of the overflowing water is fully utilized, so that the overflowing transmission mechanism 3 can drive the first water valve 21 linked with the overflowing transmission mechanism to move, the first water valve 21 is closed, a water source is cut off in time, the reliability is high, and the waste of water resources is avoided.
Referring to fig. 5, further, after the controlling the second water valve 22 to be closed, the control method further includes step S4, determining whether the overflow water amount is detected by the overflow water detection module, and if not, performing step S4 until the washing procedure is finished; if the second water valve 22 is judged to be in failure. It can be seen that after the dishwasher has sent a signal for controlling the second water valve 22 to close, if the inner container 1 of the dishwasher still overflows, it indicates that the second water valve 22 is faulty, and the water source cannot be cut off according to the set requirement.
What has been described above are merely some embodiments of the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the inventive concept thereof, and these changes and modifications can be made without departing from the spirit and scope of the invention.
