Example 2
Referring to fig. 2, a control method of a spray cleaning device according to the present embodiment, which uses the spray cleaning device according to embodiment 1, includes the following steps:
s1, starting a cleaning mode of the spray cleaning device;
s2, controlling the water inlet module to supply water to the spray arm 2 so that the spray arm 2 rotates under the driving of water pressure;
specifically, the water inlet line 31 starts to be supplied with water, and the water amount adjusting valve 32 on the water inlet line 31 is opened to allow the washing water to be introduced into the spray arm 2, so that the spray arm 2 is rotated by the water pressure. The water pump provided on the water inlet line 31 may be determined to be activated or not according to the demand.
S3, each signal detection unit 4 detects the operation parameters of the trigger part 21 passing through the signal detection unit 4 in the preset period, the operation parameters at least include the standard time point and the number of times;
specifically, after the spray arm 2 operates for a certain time, all the signal detection units 4 are controlled to start to detect the trigger part 21, so that the detection error caused by unstable water pressure at the initial stage of starting the spray arm 2 can be avoided, and the accuracy of the detection result of the operation parameter can be improved.
Two, three or four signal detection units 4 may be provided on the inner sidewall of the cleaning chamber 1 at intervals in the circumferential direction. The signal detection unit 4 is ordered as follows: according to the rotation direction of the spray arm 2, one signal detection unit 4 is taken as the first signal detection unit, the next signal detection unit 4 positioned in the rotation direction of the spray arm 2 is taken as the second signal detection unit, and so on.
In the present embodiment, after the spray arm 2 operates for a certain time, if the trigger part 21 of the spray arm 2 passes through the first signal detection unit 4 for the first time, the standard time point t1 and the number of times c1 are recorded; if the trigger part 21 continues to pass the second signal detecting unit 4, the standard time point t2 and the number c2 are recorded, and so on, and when the trigger part 21 continues to pass the last signal detecting unit 4, the standard time point tn and the number cn are recorded. Until the trigger part 21 passes the first signal detection unit 4 again, at which time the standard time tn +1 and the times c 1' are recorded, while the trigger part 21 has just rotated by a preset revolution.
In other embodiments, the timing start point may be between two adjacent signal detection units 4, i.e., the timing start point is determined from the triggering section 21 without passing through any one of the signal detection units 4. When the spray arm 2 runs for a certain time, timing is started, and a timing start point (i.e., a standard time point t0) is recorded, the trigger part 21 is located between two adjacent signal detection units 4. When the trigger part 21 of the spray arm 2 passes through the first signal detection unit 4 for the first time, the standard time point t1 and the times c1 are recorded; if the trigger part 21 continues to pass the second signal detecting unit 4, the standard time point t2 and the number c2 are recorded, and so on, and when the trigger part 21 continues to pass the last signal detecting unit 4, the standard time point tn and the number cn are recorded. Until the trigger part 21 passes the first signal detection unit 4 again, at which time the reference time tn +1 and the times c 1' are recorded. In this process, when the trigger part 21 passes the position of the start recording standard time point t0 again, the trigger part 21 rotates by just one preset period.
S4, judging whether the number of times detected by any signal detection unit 4 in the preset period is zero, if so, going to step S5, otherwise, going to step S6;
specifically, it is determined whether the number of times detected by any one of the signal detecting units 4 in the preset period is zero, that is, it is determined whether at least one of the number of times c1 and the number of times c2 … cn in the preset period is zero, and if one of the number of times is zero, two of the number of times are zero, or all of the number of times are zero, it is determined that the tableware obstructs the rotation of the spray arm 2, and the process proceeds to step S5. If the total number of times is not zero, it is determined that the dishes do not obstruct the normal rotation of the spray arm 2, and then it proceeds to step S6.
S5, determining that the spray arm 2 is blocked by tableware, controlling the water inlet module to stop supplying water to the spray arm 2, and sending an alarm signal;
specifically, when judging that the number of times that at least one signal detection unit 4 recorded in the preset period is zero, the spray arm 2 is accurately determined to be blocked by the tableware, and the water inlet module is controlled to stop supplying water to the spray arm 2 at the moment, and an alarm signal is sent out to prompt a user to readjust the placement of the tableware in the bowl basket 6, so that the tableware is prevented from blocking the normal operation of the spray arm 2.
S6, acquiring the operation parameters of at least two target objects, and calculating the current data of the spray arm 2 according to the distance between the operation parameters and the target objects;
and S7, adjusting the working state of the water inlet module at least according to the calculated current data.
It can be seen that, in the control method of the embodiment, the operation parameters of the trigger part 21 passing through each signal detection unit 4 in the preset period are detected first, and then whether the spray arm 2 is blocked by the tableware is accurately identified according to whether the times in the operation parameters are zero, so that the problem that the existing dishwasher cannot detect whether the high-size tableware blocks the spray arm is effectively solved. In addition, when the spray arm 2 rotates normally, the operating parameters of the trigger part 21 passing through each signal detection unit 4 in the preset period are detected, the current data of the spray arm 2 are calculated according to the distance between the standard time point and the target object in at least two operating parameters, and finally the working state of the water inlet module is adjusted according to the calculated current data, so that the working state of the water inlet module is automatically adjusted, the product adaptability is improved, and the tableware spray cleaning effect is improved.
In this embodiment, the current data includes a current acceleration; acquiring operation parameters of at least two target objects, and calculating current data of the spray arm 2 according to the operation parameters and the distance between the target objects, wherein the method specifically comprises the following steps:
s61, acquiring a standard time point t1 'and a standard time point t 2' of two target objects;
specifically, within the range of the selected target objects, the sorting is performed in accordance with the rotation direction of the spray arm 2, wherein one target object is the first one, and the other target object is the second one. When the trigger part 21 passes through the first target object for the first time, recording a standard time point t 1' at this time; when the spray arm 2 continues to pass the second target object, the standard time t 2' is recorded; when the trigger 21 passes the first target object again, the standard time t 3' is recorded. In this process, the trigger 21 rotates for a preset period.
S62, the current acceleration a of the spray arm 2 is calculated according to the following formula,
where t1 ' is a standard time point from the first target object, t2 ' is a standard time point from the first target object to the second target object in the nozzle arm rotation direction, t3 ' is a standard time point from the second target object to the first target object in the nozzle arm rotation direction, s1 ' is a distance from the first target object to the second target object in the nozzle arm rotation direction, and s2 ' is a distance from the second target object to the first target object in the nozzle arm rotation direction.
Therefore, in a preset period, the current acceleration a of the spray arm 2 in the preset period is calculated according to the distance between the standard time point acquired by the two target objects and the target objects, so that the control module 5 can adaptively adjust the working state of the water inlet module according to the calculated current acceleration a, the water pressure adjusting effect of the spray arm 2 is improved, and the tableware cleaning effect is improved.
Referring to fig. 3, in this embodiment, the adjusting the working state of the water inlet module according to at least the calculated current data specifically includes:
s71, extracting the pre-stored standard data points corresponding to the standard time points from the storage module according to the standard time points of two target objects;
specifically, when two of the target objects are the first and second signal detecting units 4, the standard time points include a standard time point t1 'and a standard time point t 2', when the standard time point t1 is the standard time point t1 ', and the standard time point t2 is the standard time point t 2'.
