Referring to fig. 1 to 6 together, a control method of a washing appliance system according to an embodiment of the present invention is used for a washing appliance system 100 according to an embodiment of the present invention. The washing appliance system 100 includes a washing appliance 10, a first waterway 20, a second waterway 30, and a first flowmeter 40. The washing appliance 10 may be, for example, a dishwasher (e.g., a tub dishwasher), a washing machine, a fruit and vegetable washer, or the like. The first waterway 20 is connected to the washing appliance 10. The second waterway 30 is connected to the washing appliance 10. The first waterway 20 is for supplying the first water to the washing appliance 10. The second waterway 30 serves to supply the second water to the washing appliance 10. The first flowmeter 40 is disposed in the first waterway 20.
The control method of the washing electrical system comprises the following steps:
step S1: opening the first waterway 20;
step S2: reading the first pulse number of the first flowmeter 40 every a first preset time length, determining whether the first pulse number is greater than or equal to the first preset pulse number, if so, entering step S3, otherwise, entering step S4;
step S3: maintaining the first waterway 20 in an opened state and returning to step S2;
step S4: the first waterway 20 is closed and the second waterway 30 is opened.
Thus, when the first pulse number of the first flowmeter 40 is smaller than the first preset pulse number, it can be determined that the first waterway 20 is abnormal in water inflow due to blockage or diversion and other abnormal factors, so that when the first waterway 20 is abnormal in water inflow, the first waterway 20 can be closed timely and switched to the second waterway 20 to continue supplying water to the washing appliance 10, and then normal operation of the washing appliance 10 can be ensured.
The first water supplied from the first water path 20 to the washing appliance 10 may be purified water, i.e., water containing no impurities (e.g., organic contaminants, inorganic salts, additives, etc.) or bacteria. The second water path 30 may supply the second water to the washing appliance 10 with tap water. In addition, the first preset duration may be set according to specific situations. The first preset number of pulses may be set according to the specific situation. After the program of the control method of the washing electric system is started, the first preset pulse number can be preset directly according to the washing requirement of the washing electric system 10.
It will be appreciated that after the washing appliance system 100 is turned on and the washing appliance 10 enters the washing stage, the first waterway 20 may be opened again. In addition, after the washing of the washing appliance 10 is completed, the washing appliance system 100 may be turned off to terminate the flow.
Referring to fig. 5, in the present embodiment, the washing appliance system 100 includes a first valve body 50, a second valve body 51, and a control device 60. The first valve body 50 is disposed in the first waterway 20. The second valve body 51 is provided in the second waterway 30. The control device 60 is electrically connected to the first valve body 50, the second valve body 51 and the first flowmeter 40. The control device 60 is used for controlling the first valve body 50 to open the first waterway 20, and is configured to read the first pulse number of the first flowmeter 40 every a first preset time period, and is configured to determine whether the first pulse number is greater than or equal to the first preset pulse number, and to keep the first waterway 20 in an open state when the first pulse number is greater than or equal to the first preset pulse number, and to continue to read the first pulse number of the first flowmeter 40 every a first preset time period, and to control the first valve body 50 to close the first waterway 20 and to control the second valve body 51 to open the second waterway 30 when the first pulse number is less than the first preset pulse number. In this embodiment, when the first pulse number of the first flowmeter 40 is greater than or equal to the first preset pulse number, it may be determined that the first waterway 20 is normally water feeding, and at this time, the water feeding flow of the first waterway 20 is not lower than the first preset flow. The first preset flow is the minimum water inflow required by ensuring the normal operation of the washing appliance 10. The first preset flow rate can be set according to specific conditions. For example, in some examples, the first water of the first water path 20 is purified water, the water inflow required for one time of water inflow of the washing appliance 10 can be set to be X liters of water, and the number of pulses P needs to be read when X/L of water is independently fed Pure water And set a first preset flow L 1 Liter/min. The water inflow rate in the first waterway 20 is a first preset flow rate L 1 When the critical point of liter/min is up, the water inlet time is T 1 =x/L1. The number of pulses per minute is P Pure 1 ＝P Pure water /T 1 . Then the first preset time period is set as T d When the first pulse number P is obtained at the critical point where the water inflow rate of the first waterway 20 is the first preset flow rate L1L/min Pure d ＝P Pure 1 *T d /60, i.e. at T d The first pulse number read in time is smaller than P Pure d It is considered that the inflow of pure water is abnormal.
Referring to fig. 2, in some embodiments, after the first waterway 20 is opened, a control method of the washing appliance system includes:
step S5: and determining whether the opening time of the first waterway 20 is longer than the second preset time, if so, entering step S2, and if not, returning to step S5. Thus, when the first water is fed, after the first water feeding time is longer than the second preset time, the first pulse number of the first flowmeter 40 is read every other the first preset time, so that inaccurate pulse number reading caused by the irregularity of the first flowmeter 40 when water feeding is started can be prevented, and the reading accuracy can be improved.
It should be noted that the second preset duration can be set according to specific situations.
In this embodiment, the control device 60 is configured to determine whether the opening duration of the first waterway 20 is longer than the second preset duration after the first waterway 20 is opened, and to read the first pulse number of the first flowmeter 40 every first preset duration after the opening duration of the first waterway 20 is longer than the second preset duration, and to continuously determine whether the opening duration of the first waterway 20 is longer than the second preset duration when the opening duration of the first waterway 20 is shorter than or equal to the second preset duration.
Referring to fig. 3, in some embodiments, step S1 includes: after the first waterway 20 is opened, reading the accumulated pulse number of the first flowmeter 40 and accessing the first accumulated pulse number;
after step S3, the control method of the washing appliance system includes:
step S6: determining whether the first accumulated pulse number is greater than or equal to a preset total pulse number, if so, entering a step S7, otherwise, returning to the step S6;
step S7: the first waterway 20 is closed.
Thus, when the first accumulated pulse number of the first flowmeter 40 reaches the preset total pulse number, it can be determined that the total water inflow of the first waterway 20 has reached the preset total water inflow (the water inflow required by the normal washing of the washing appliance 10 can be satisfied), and at this time, the first waterway 20 can be closed to stop the water inflow.
It should be noted that the preset total pulse number can be set according to specific situations. After the washing appliance 10 is turned on, a preset total pulse number may be correspondingly set according to the washing condition of the washing appliance 10.
In this embodiment, the control device 60 is configured to read the first accumulated number of pulses of the first flowmeter 40 after the first waterway 20 is opened, and is configured to access the first accumulated number of pulses, and is configured to determine whether the first accumulated number of pulses is greater than or equal to a preset total number of pulses, and is configured to control the first valve body 50 to close the first waterway 20 when the first accumulated number of pulses is greater than or equal to the preset total number of pulses, and is configured to continuously determine whether the first accumulated number of pulses is greater than or equal to the preset total number of pulses when the first accumulated number of pulses is less than the preset total number of pulses.
In certain embodiments, step S4 comprises: after closing the first waterway 20, a first prompt message prompting the water inlet failure is sent. In this way, when the water inlet of the first waterway 20 is abnormal, prompt can be timely given.
It should be noted that the first prompt information may be an audio alarm information, or may be a video prompt information.
In this embodiment, the washing appliance system 100 includes a reminder device 70. The prompting device 70 is electrically connected to the control device 60. The control device 60 is configured to control the prompting device 70 to send out a first prompting message for prompting the water inlet failure after closing the first waterway 20. The prompting device 70 may be, for example, a buzzer.
Referring to fig. 4, in some embodiments, the washing appliance system 100 includes a second flowmeter 41. The second flowmeter 41 is provided in the second waterway 30. After the second waterway 30 is opened, the control method of the washing electric system includes:
step S8: reading the second pulse number of the second flowmeter 41 every third preset time period, determining whether the second pulse number is greater than or equal to the second preset pulse number, if yes, proceeding to step S9, otherwise proceeding to step S8;
step S9: maintaining the second waterway 30 in an opened state and returning to step S8;
step S10: and sending out second prompt information for prompting the water inlet failure.
In this way, when the second pulse number of the second flowmeter 41 is smaller than the second preset pulse number, it can be determined that the actual flow rate in the second waterway 30 is lower than the preset flow rate, that is, the second waterway 30 is blocked, and other abnormal factors can be timely indicated.
It should be noted that the third preset duration may be set according to a specific situation.
In the present embodiment, the control device 60 is electrically connected to the second flowmeter 41. The control device 60 is configured to read the second pulse number of the second flowmeter 41 every third preset time period after the second waterway 30 is opened, determine whether the second pulse number is greater than or equal to the second preset pulse number, keep the second waterway 30 in an open state when the second pulse number is greater than or equal to the second preset pulse number, continuously read the second pulse number of the second flowmeter 41 every third preset time period, and control the prompting device 70 to issue a second prompting message for prompting the water inlet failure when the second pulse number is less than the second preset pulse number.
It should be noted that the second water channel 30 may be used alone to supply water to the washing appliance 10. When the water inflow required for the washing appliance 10 to feed water once is set as X liters of water and the second water of the second waterway 30 is tap water, if the second waterway 30 is adopted singly to feed X liters of water, the total pulse number required to be read in the set time is set as P Self-supporting . Then, it is possible to determine whether the second waterway 30 is abnormal by not only reading the second pulse number of the second flowmeter 41 every third preset time period (the third preset time period at this time is a unit time, which may be set to 1 minute, for example) and determining whether the second pulse number of the second flowmeter 41 is greater than or equal to the second preset pulse number, but also determining whether the total pulse number of the second flowmeter 41 reaches the above-described P when the total water intake time of the second waterway 30 exceeds the set time (may be 4 minutes, for example) Self-supporting To determine whether the second waterway 30 is abnormal in water inflow. When the total water inlet time of the second water path 30 exceeds the set time, the total pulse number of the second flowmeter 41 is smaller than P Self-supporting And if not, determining that the second waterway 30 is abnormal in water inflow, and otherwise, determining that the second waterway 30 is normal in water inflow.
In certain embodiments, step S1 comprises: after the first waterway 20 is opened, reading a first accumulated pulse number of the first flowmeter 40 and accessing the first accumulated pulse number;
the step S4 includes: after the second waterway 30 is opened, reading a second accumulated pulse number of the second flowmeter 41 and accessing the second accumulated pulse number;
after step S4, the control method of the washing appliance system includes:
step S7: the second preset accumulated pulse number of the second flowmeter 41 is determined according to the accessed first accumulated pulse number, and it is determined whether the second accumulated pulse number is greater than or equal to the second preset accumulated pulse number, if yes, the second waterway 30 is closed, if not, the step S11 is returned.
In this way, even after switching to the second waterway 30, when the total water inflow of the first waterway 20 and the second waterway 30 reaches the water required for washing the electric appliance 10, the second waterway 30 can be closed in time, and excessive water inflow can be prevented.
It will be appreciated that when the water inflow required for one time of water inflow of the washing appliance 10 is set to be X liters of water, the total number of pulses to be read when the water inflow of the second waterway 30 is solely adopted is P Self-supporting . After the first waterway 20 is closed due to water inlet abnormality, the recorded first accumulated pulse number read by the first waterway 20 is P Pure s . After the second waterway 30 is opened, in order to ensure the total water inflow is X liters, the influence of the water inflow of the first waterway 20 is eliminated, and the second preset accumulated pulse number P of the second waterway 30 is also required to be read From s ＝P Self-supporting *(P Pure water -P Pure s )/P Pure water . So that the total pulse number of the second waterway 30 is P From s After that, the second waterway 30 can be closed to stop the inflow of water.
In the present embodiment, the control device 60 is configured to read the first accumulated number of pulses of the first flowmeter 40 after the first waterway 20 is opened, to access the first accumulated number of pulses, to read the second accumulated number of pulses of the second flowmeter 41 after the second waterway 30 is opened, to access the second accumulated number of pulses, to determine the second preset accumulated number of pulses of the second flowmeter 41 according to the accessed first accumulated number of pulses, to determine whether the second accumulated number of pulses is greater than or equal to the second preset accumulated number of pulses, and to control the second valve body 51 to close the second waterway 30 when the second accumulated number of pulses is greater than or equal to the second preset accumulated number of pulses, and to continuously determine whether the second accumulated number of pulses of the second flowmeter 41 is greater than or equal to the second preset accumulated number of pulses when the second accumulated number of pulses is less than the second preset accumulated number of pulses.
In certain embodiments, the first waterway 20 includes a first waterway 21 and a second waterway 22. The first water diversion path 21 is connected with the washing appliance 10. The first valve body 50 is provided in the first water diversion channel 21. The second tap 22 is connected to the tap 221. Thus, the structure of the water path is simpler, and the first water of the first water path 20 can be split for different purposes, so that the user experience is improved. For example, when the first water of the first waterway 20 is purified water, the second waterway 22 may be used to connect a tap 221 as a direct drinking tap for a user to drink. It should be noted that, when the first water of the first water path 20 is purified water, after the user opens the direct-drinking tap, the diversion of the second water path 22 may cause the water yield of the first water path 21 to decrease, and may cause the first pulse number of the first flowmeter 40 to be smaller than the first preset pulse number within the first preset time period read by the control device 60, but when the first pulse number of the first flowmeter 40 is smaller than the first preset pulse number within the first preset time period read by the control device 60, the control method of the washing electrical system of the embodiment can switch to the second water path 30 in time after the water inlet of the first water path 21 is abnormal, so as to ensure the normal operation of the washing electrical system 10.
In the present embodiment, the washing appliance system 100 includes a water purifier 11. The first waterway 20 is connected to the water purifier 11 and the washing appliance 10. The first water of the first waterway 20 is purified water. That is, the water purifier 11 supplies purified water to the washing appliance 10 through the first waterway 20. The second waterway 30 is tap water.
Some or all of the functions of the control device 60 of the embodiments of the present invention may be implemented by a controller or processor of the washing appliance or water purifier itself, or a control board, or a computer board. The control device 60 may also be made as a separate control box or control terminal comprising a controller, processor, control board or computer board, mounted on the washing appliance or water supply appliance, or elsewhere than the washing appliance or water supply appliance. It is also possible that part of the functions of the control device 60 are implemented by a controller or a processor of the washing appliance itself, or a control board, or a computer board, and the other part of the functions of the control device 60 are implemented by a controller or a processor of the water supply appliance itself, or a control board, or a computer board, etc.
In the present embodiment, after the washing appliance 10 enters the washing stage, washing water may be supplied to the washing appliance 10 through the first waterway 20 or the second waterway 30. The washing stage includes a pre-washing stage, a main washing stage, and a rinsing stage.
The pre-washing stage of the washing appliance 10 mainly performs a preliminary washing of the articles (such as tableware or fruits and vegetables, etc.) placed in the washing appliance 10 to wash out the larger stains on the articles, and then the second water washing of the second waterway 20 may be directly performed. The main wash stage of the washing appliance 10 requires an increase in the wash water to be heated to a higher temperature which gives the detergent greater activity so that the dishes to be cleaned can be cleaned relatively thoroughly. The first water of the first waterway 20 may be used for cleaning at this time to secure the cleaning effect.
During the process of supplying water from the first water path 20 to the washing appliance 10, if the first pulse number of the first flowmeter 40 read by the control device 60 every a first preset time period is greater than or equal to the first preset pulse number, the first water path 20 is kept in an open state, and the first water path 20 can be closed to stop water inflow when the first accumulated pulse number of the first flowmeter 40 reaches the preset total pulse number (at this time, the total water inflow of the first water path 20 reaches the preset total water inflow). If the first pulse number of the first flowmeter 40 read by the control device 60 is smaller than the first preset pulse number (possibly caused by the blockage of the filter element of the water purifier 11 or the diversion of the first waterway 20), the control method of the washing electric system of the embodiment can switch to the second waterway 30 in time after the water inlet of the first water diversion channel 21 is abnormal so as to ensure the normal operation of the washing electric system 10. The control device 60 can control the prompting device 70 to send out prompting information for prompting water inlet faults so as to prompt a user to replace the filter element of the water purifier 11 in time or close the second water diversion channel 22.
Further, the washing stage of the washing appliance 10 includes a rinsing stage. The pre-wash stage, the main wash stage and the rinse stage are sequentially performed. The washing water in the rinsing stage is clean water without detergent, and is used for cleaning the detergent such as foam and the like remained on the tableware to be cleaned. The rinsing stage may be performed with purified water of the first waterway 20 to ensure a rinsing effect. That is, the control device 60 can be used to determine whether the main washing stage is finished, and to control the washing appliance 10 to enter the rinsing stage when the main washing stage is finished, and to control the first valve body 50 to open the first waterway 20 after the washing appliance 10 enters the rinsing stage, so as to perform washing using the first water of the first waterway 20 in the rinsing stage.
