Example 2
As shown in fig. 3, in the present embodiment, there is provided a washing machine including a controller configured to implement any one of the control methods of embodiment 1 to perform a mid-course laundry adding operation in a washing course.
Preferably, the washing machine further comprises:
a housing formed with an accommodation chamber;
a laundry treating tub disposed within the accommodating chamber;
a water tank for temporarily storing water discharged from the inside of the laundry treating tub during a midway laundry adding process, wherein: the water tank is arranged above the clothes treatment barrel and is provided with a water inlet channel and a water return channel which are respectively communicated with the clothes treatment barrel.
Preferably, the washing machine further comprises: and a detergent box for putting detergent into the laundry treatment tub. Wherein the detergent box is provided with a water return port communicated with the water return channel so as to lead the water in the water tank to flow back into the clothes treatment barrel through the detergent box.
In the clothes adding process of the washing machine in the embodiment, water in the clothes treatment barrel enters the water inlet channel (the water channel 1 in the figure) through the shunt valve and enters the water tank for temporary storage through the water inlet channel, and when clothes are added, the water supply valve on the water return channel is opened, and the water returns to the clothes treatment barrel through the detergent box. The mode saves pipelines, reduces the change to the internal structure of the washing machine and further reduces the cost.
In the embodiment, the washing machine realizes the function of adding clothes in the middle through a logic control program under the condition that the structure of the door body is not changed.
When a user has clothes adding requirements in the main washing water inlet and rinsing stages, the user can click the option of 'midway clothes adding', the water level sensor firstly judges the water level, and if the water level is higher than the door opening water level at the moment, a water discharging program is operated. The partition valve of the drain pump opens the water inlet channel and delivers water to the dedicated water tank under the action of the drain pump. And when the water level sensor judges that the water level is lower than the door opening water level, closing the drainage pump to wait for the user to add clothes. After the user adds clothes, the user clicks start/pause, the water supply valve is switched from off to on, water in the water tank flows into the inner barrel from the detergent box, and the washing program is continuously operated.
It should be noted that the capacity of the dedicated water tank is obtained by the lowest door opening level, which is the level that can be reached when the load is at the highest level. In addition, a prompt module for adding clothes halfway can be optimized, an option of 'adding clothes halfway' is added in the conventional mode selection, when the mode is used, three displays of 'less', 'middle' and 'more' can be displayed on the display panel, a small amount of clothes can be added, a middle amount of clothes can be added and a large amount of clothes can be added correspondingly, when the logic judgment prompts that the user puts in clothes of corresponding levels, the corresponding load levels can flash and/or send corresponding voice prompts, and the user can be intuitively made to understand the put levels.
Based on the control method in embodiment 1, a specific operation process of the washing machine is also provided in this embodiment. When a user puts forward a requirement of adding clothes halfway, the drum washing machine firstly judges that the washing machine is in a washing process state, if the washing process of the washing machine is at or before washing weighing, the rotating speed of the washing machine is reduced to 50rpm or below, the door lock is opened, and the display module prompts the user to add clothes halfway, and weighing, water inlet, washing, rinsing and dewatering are carried out again.
When the washing process of the washing machine is in a main washing water inlet stage, whether the current water level SW is smaller than a preset door lock opening water level SW1 or not is judged, if SW is larger than SW1, a drainage pump is opened to discharge water to a special water tank, after midway clothes adding is finished, the water can be pumped back into a cylinder, and then washing weighing data M and the maximum washing capacity M of the washing machine are compared. If SW < SW1, the inner drum of the washing machine is reduced to 50rpm or below; then it is performed whether the washing stage remaining time Tx is greater than half the total washing stage time T. If Tx is greater than T/2, the clothes weight M obtained by washing weighing is compared with the maximum washing capacity M of the washing machine, and then the user is prompted to put in the level of the load. If Tx < T/2, the user is directly prompted to deliver only "few" levels of load without comparing the values of M and M.
As shown in fig. 2, is a logic for comparing a weight M of clothes according to a washing weight with a maximum washing capacity M of the washing machine. When 0< M/10, the user is prompted that "little" or "medium" or "many" loads can be added halfway; when M/10< M/3, the user is prompted to add "little" load or "medium" load halfway; when M/3< M < M, prompting the user to add a "less" load halfway; otherwise, the user is prompted that the clothes cannot be added halfway.
When the washing machine stage enters the rinsing stage, when a user has a requirement for adding clothes halfway, the turbidity value is judged before the door lock is opened, besides the water level and the washing time, the voltage value at the moment is judged by the turbidity sensor to be compared with the clear water voltage, and the reference voltage U1 (normal) and U2 (dirty) with 2 grades of pollution turbidity of the turbidity sensor are set. When U0> U2, the water level and washing time are judged immediately to determine the load level of the clothes put in by the user. When U0< U2, it indicates that the main washing solution is dirty, and the rotation speed is reduced to 50rpm or below, and the user is prompted to throw "less" load or no load.
In the rinsing stage and after the rinsing stage, if the user has a demand for clothes halfway, the "rinsing dehydration" program is directly run. If the user has the requirement of adding clothes in the middle of the dehydration stage, the 'single dehydration' program is directly operated.
The "low" load for the prompt drop indicates: the clothes with the weight below M/10 can be roughly smaller clothes such as socks, towels and the like. "medium" load means: the clothes with the weight of M/10 to M/3 can be roughly short-sleeved clothes, shirts and the like. "Multi" load means: clothing items having a weight ratio of M/3 may be, for example, several items of clothing such as jackets, etc.
Exemplary embodiments of the present disclosure are specifically illustrated and described above. It is to be understood that the present disclosure is not limited to the precise arrangements, instrumentalities, or instrumentalities described herein; on the contrary, the disclosure is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
