Description
The technical field is as follows:
the invention relates to a heating control system and a heating control method of a multi-module clothes treatment device, and belongs to the field of consumer electronics.
Background art:
in recent years, with the technical upgrading and consumer upgrading of the washing machine industry, the subdivision requirements of users on the washing machine are gradually increased, wherein the requirements on cleanness, energy conservation and health are most prominent. The clean, healthy and efficient concepts are embodied on the washing machine products for washing clothes in different zones and classifying the clothes, and the multi-drum washing machine discussed by the invention is a typical representative of the washing clothes in different zones and classifying the clothes.
Two barrels of a double-barrel washing machine generally have a washing and heating function, and two barrels of a washing machine with a higher configuration have a drying and heating function. After both the two machine barrels are started for washing, in a washing heating stage or a drying heating stage, in order to avoid overhigh power and overlarge current caused by the fact that heaters of the two barrels are started simultaneously, a mode of sequentially heating the two barrels is adopted for heating. At present, in the industry, a hardware device is adopted to perform mutual exclusion protection on heating, a method of confirming respective heating time length limit values and specific heating time lengths of two cylinders and determining a heating sequence by comparing the relationship between the total heating time length of the two cylinders and the heating time length limit value of each cylinder is also adopted, and a method of determining the heating sequence according to the capacity of the cylinders or directly defining the heating priority of machine cylinders is also adopted.
When two drums of washing machines (generally two drums) have heating functions, the current limitation of household appliances can absolutely avoid the simultaneous heating of the heaters of the two washing drums, otherwise, the power and the current are too high, the computer controller, the power line and the like can bear too large current and cause rapid heating, so that the performance is reduced, and more serious heating can cause damage to components or the power line or even fire.
After the double-drum washing machine is started to operate simultaneously, the occurrence time of washing heating or drying heating is independent and preset respectively; however, the operation time of the washing machine is not fixed and very accurate, and sometimes, time deviation occurs due to functions such as water pressure difference, water replenishing, defoaming, cooling, dewatering eccentricity try and the like, or the time for opening the two cylinders by a user is random, so that the washing heating or drying heating of the two cylinders meet at random, and at the moment, the two cylinders must be prevented from being heated at the same time, so that the heating of the two cylinders needs to be carried out in sequence, namely heating mutual exclusion protection. Poor handling can lead to dangerous situations where two drums are heated simultaneously, or situations where one drum is not heated, or situations where two drums are heated in sequence with increased time and reduced washing efficiency, etc.
Therefore, there is a need to improve the prior art to solve the deficiencies of the prior art.

s04: making a heating strategy;
s05: confirming and adjusting a heating sequence;
s06: preferentially heating the processed object;
s07: and (4) processing the heating conflict for multiple times.
Further, step S01 is specifically as follows: before the first washing module and the second washing module run, a user sets the washing mode, the heating temperature and the heating time of each module.

Fig. 3 is a software flowchart of a heating control method of a multi-module laundry treating device according to the present invention.
The specific implementation mode is as follows:
the invention will be further described with reference to the accompanying drawings.
In the present invention, a double-cylinder washing machine is used as a representative of a multi-cylinder washing machine for explanation (two cylinders may be respectively defined as a first washing module and a second washing module).
The heating control system of the multi-module clothes treatment device comprises a first washing module and a second washing module, wherein the first washing module comprises a first time calculating and controlling unit 310, a first temperature sensing unit 311 and a first heating executing unit 312, the second washing module comprises a second time calculating and controlling unit 320, a second temperature sensing unit 321 and a second heating executing unit 322, and the first time calculating and controlling unit 310 and the second time calculating and controlling unit 320 are used for calculating washing time, heating time, time countdown and heating target temperature; a first temperature sensing unit 311 and a second temperature sensing unit 321 for sensing a real-time temperature of the laundry module; a first heating execution unit 312 and a second heating execution unit 322 for controlling the switch of the heater.
The heating control system of the multi-module laundry treating apparatus of the present invention further includes a heating control scheduling unit 330 for performing analysis and scheduling of heating control according to data conditions of each unit of the first laundry module and the second laundry module.
And defining the first washing module of the two washing modules as a machine cylinder which is operated firstly, and defining the second washing module as a machine cylinder which is operated later. The machine barrel is operated firstly to reach washing heating or drying heating, namely the machine barrel is operated firstly to occupy the heating authority, and then the control strategy when the machine barrel is operated to reach the washing heating or drying heating is researched. The method mainly comprises the following steps:
s01: the heating time period of each module is determined. Before the two washing modules run, a user sets parameters such as washing modes, heating temperatures and the like of the modules, at this time, the heating time of the two washing modules is clearly defined, for example, the first washing module selects wool washing +40 ℃, the heating time is T1 (for example, 30min), the second washing module selects cotton and linen washing +60 ℃, and the heating time is T2 (for example, 70 min).
S02: the heating stages are necessarily reached in sequence. The two cylinders are opened to operate, the first washing module operates the cylinder firstly to reach a heating stage, the second washing module operates the cylinder afterwards to be in a working stage before the heating stage, and the two cylinders do not generate mutual exclusion of heating working conditions. The heating time period T1 of the first laundry module during the heating phase is counted down, i.e. dynamically changed (the heating time period T2 of the second laundry module has the same logic).
S03: and the second washing module performs heating analysis. After the second washing module reaches the heating stage, the first washing module is in a heating state, and the second washing module wants to heat. The second washing module has two choices: (1) after the heating of the first washing module is finished, heating is carried out again, and basic washing actions are carried out in the waiting process; (2) and in the heating stage, the heating permission of the first washing module is preempted, so that the first washing module stops heating and enters heating waiting, and therefore the second washing module is in heating and the first washing module is in heating waiting.
S04: and (5) establishing a heating strategy. Firstly, real-time heating time lengths T1 and T2 of a first washing module and a second washing module are obtained through a time unit of a computer controller, and real-time water temperatures Temp1 and Temp2 of the first washing module and the second washing module are obtained through a temperature sensor unit. The magnitude relationship of T1 and T2 was then compared: (1) if T2> is T1, namely the washing module II which reaches the heating stage needs longer heating time, the washing module I continues heating, and the washing module II waits for heating; (2) if the heating time required by the second washing module which reaches the heating stage after T2< T1 is shorter, the first heating module stops heating, enters a heating waiting state, and the second heating module starts heating. (3) The above-mentioned (1) and (2) are the basic heating control method of the present invention, that is, the dynamic heating time periods of the two washing modules are compared to determine the heating sequence; furthermore, in order to make the heating sequence more reasonable and efficient, the heating control method of the invention adds the following control logics: and (2) adding two correction factors on the basis of (2) to decide whether (2) is executed or not (note: the two factors have no primary and secondary scores and no order score, and can be interchanged). The factor one is: if T1 is smaller than a predetermined value T1x (e.g. 5min), the step (2) is not executed, i.e. the remaining heating time of the first washing module is already short, and the heating sequence is not switched even if the heating time of the second washing module is shorter. Factor two: the relation between Temp1 and the heating target temperature T1target of the first washing module is that (2) will not be executed if Temp1 and T1target are very close (for example, 3 ℃), i.e. the real-time temperature of the first washing module is already very close to the target temperature, and even if the heating time of the second washing module is shorter, the heating sequence is not switched.
S05: heating sequence confirmation and adjustment. According to the heating strategy described in S04, the actual heating sequence is adjusted as follows: and if the condition (1) is met, the first washing module continues heating, and the second washing module waits to heat. The heating of the first washing module can be directly stopped and the heating of the second washing module can be started when the condition (2) is met; it can also be determined by combining the first and second factors, such that when T1 is less than a predetermined time or when Temp1 is very close to the heating target, the first washing module continues heating, and the second washing module waits to heat.
After the heating sequence is determined, the washing module in heating is called as a "preferential heating module", and the other washing module is called as a "waiting heating module".
S06: the processing after the completion of heating is prioritized. And after the heating of the priority heating module is finished, the subsequent washing stage is carried out, and at the moment, the waiting heating module exits from waiting and starts heating. It should be clear that, after the preferential heating module completes heating and waits for the heating module to start heating, if the laundry module that completes heating needs to heat again due to the need of the laundry process, the heating analysis and decision process of S02-S05 is not performed at this time, but the judgment and decision of the heating mutual exclusion can be restarted again only after the two laundry modules complete one-time complete heating mutual exclusion protection, heating sequence adjustment and heating in sequence after the current laundry module that is heating, namely the "waiting heating module" before is heated. This is done to avoid frequent heating mutex and adjustment resulting in multiple interruptions of a single heating process, affecting heating efficiency and washing efficiency.
S07: and (4) processing the heating conflict for multiple times. In the whole washing process, two washing modules may form heating conflict more than once, and heating related data acquisition, analysis and processing should be carried out according to the heating control methods of S01-S06. The process from S01 to S07 is the heating control method of the multi-drum washing machine.
The software flow chart of the invention is as follows:
And step 204, after the second washing module reaches a heating stage, the second washing module cannot be directly heated, and the two washing modules are heated simultaneously, so that the risks of overhigh power and overlarge current are caused, and the heating sequence analysis is required.
At step 205, a heating sequence analysis is initiated. The heating time durations T1 and T2 of the two washing modules are compared, if the time duration T2 is not shorter than the time duration T1, the heating is continued in the first washing module and the heating is waited in the second washing module according to the step 206. If the time T2 is shorter than the time T1, then the heating sequence adjustment can be performed as shown in step 211: the first washing module stops heating, and the second washing module starts heating; other influencing factors may also be taken into account, step 207.
Description of the drawings: the two factors of step 207 and step 209 have no primary and secondary scores and no order score and can be interchanged.
In the washing and drying processes of the washing machine with the functions of the multiple washing modules, as long as heating conflicts occur, the relation of the real-time heating time length of each module, the residual heating time length of the heating module, and the relation of the real-time temperature of the heating module and the target temperature are all considered to decide the heating sequence, so that the condition that the washing machine heats according to the sequence and does not heat simultaneously when the multiple modules heat simultaneously is ensured. By the heating control method, the laundry module with relatively short heating time, short residual heating time and temperature close to the heating target temperature can be preferentially heated, and the other laundry module is in the laundry action of heating waiting until the heating module finishes heating and exits the heating action.
The foregoing is only a preferred embodiment of this invention and it should be noted that modifications can be made by those skilled in the art without departing from the principle of the invention and these modifications should also be considered as the protection scope of the invention.
