Description

Technical Field

[0001] The invention belongs to the field of clothing washing, and in particular relates to a control method for automatically adding detergent. Background Art

[0002] In modern society, most of the current drum washing machines have a "mid-cycle door opening" function. The use of this function has certain prerequisites. Only when the water level in the drum is below the safety line can the drum door be opened to add / remove clothes, otherwise the washing water in the drum may overflow. If the user wants to add clothes mid-cycle, but the current water level does not meet the requirements, the washing machine will automatically drain the water until the water level drops to the safety line; if the time for adding clothes mid-cycle is set during the washing process when the washing machine adds detergent, the washing machine will drain the detergent and other detergents at the same time; however, many current washing machines will only add water but not detergent after the user adds / removes clothes after draining the water to meet the "mid-cycle door opening" water level requirements, which directly affects the washing effect, or the detergent is added but the amount of addition is unclear, and adding too much or too little detergent will affect the washing effect.

[0003] The present invention is proposed in view of the above problems in order to solve these problems. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a control method for automatically adding detergent. Through the invention, a function of automatically adding detergent when adding / removing clothes in the middle is provided to meet the user's requirements for the washing effect of clothes.

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0006] A control method for automatically adding detergent, characterized in that: it is judged whether the washing machine is in the washing stage when the door is opened halfway. If so, the detergent content in the washing machine after drainage is calculated after the door is closed, and the amount of detergent that needs to be added to the washing machine after drainage is calculated based on the detergent content in the washing machine after drainage, the amount of washing water required in the washing machine after the door is opened halfway, and the initial amount of detergent added.

[0007] Furthermore, the initial amount of detergent is D 1 , the washing water volume is V 1 , the amount of water discharged by the washing machine after the door is opened is V p ,

[0008] According to the initial amount of detergent D 1 and washing water intake V 1 And the washing machine's drainage volume V p Calculate the detergent content D in the washing water after drainage 2 ,

[0009] D 2 =D 1 -D 1 / V 1 *V p .

[0010] Furthermore, if the door is opened midway to add and / or take out clothes, the initial weight M of the clothes in the washing machine 1 ,

[0011] Obtain the clothing weight change M according to the weighing module b ,

[0012] The amount of washing water V that needs to be replenished when adding and / or removing clothes from the washing machine is calculated based on the weight change of the clothes Mb. 3 .

[0013] Further, according to the initial amount of detergent D 1 , Detergent content in washing water after drainage D 2 , clothing weight change M b , Washing water intake V 1 , the amount of washing water required to be replenished when adding and / or removing clothes from the washing machine V 3 , calculate the detergent D that needs to be replenished,

[0014] D=D 1 / V 1 *V 3 -D 2 .

[0015] Furthermore, the weight change of the clothes Mb is obtained according to the weighing module, and the weight change of the clothes M b , when you open the door to take out clothes, then M b <0, if you open the door to add clothes in the middle, then M b >0.

[0016] Furthermore, when clothes are added and / or removed during the operation of the washing machine, the amount of washing water V is obtained according to the water level detection module or the weighing module. p .

[0017] Furthermore, the initial amount of detergent D 1 It is based on the initial weight M of the clothes in the washing machine. 1 and the amount of washing water in the washing machine,

[0018] A control system is provided in the washing machine, and the amount of washing water can be set automatically by the control system in the washing machine or manually by the user.

[0019] Furthermore, the weight change Mb of the clothes is obtained by weighing the weight change of the clothes before and after adding and / or taking out the clothes through a weighing module, and a weight sensor is provided on the weighing module.

[0020] The weight sensor is used to measure the weight change Mb of the clothes before and after adding and / or taking out the clothes.

[0021] Further, when it is determined that the washing machine is in a non-washing stage at the time of door opening,

[0022] The amount of detergent that needs to be replenished is not calculated.

[0023] Only the amount of wash water that needs to be replenished after the door is closed and drained is calculated.

[0024] Furthermore, a washing machine for automatically dispensing detergent is provided with a weighing module, a water level detection module, a processing module, and a control module.

[0025] The washing machine is provided with a weighing module, and the washing machine uses the weighing module to weigh the weight inside the washing machine before and after the door is opened;

[0026] The washing machine is provided with a processing module, which calculates the detergent content D2 in the washing machine after drainage, the weight change in the washing machine before and after the door is opened, and the detergent D that needs to be replenished;

[0027] After the door of the washing machine is opened midway, the water level detection module obtains the drainage volume Vp of the washing water.

[0028] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0029] The function of automatically adding detergent when adding / removing clothes during the "mid-cycle door opening" of the washing machine can improve the washing effect. Since clothes need to be added or removed during the washing process, opening the door mid-cycle will cause the loss of detergent. The automatic detergent addition function can ensure that the washing machine will automatically add an appropriate amount of detergent when the washing process is resumed after each mid-cycle door opening. This can ensure that the detergent is in full contact with the clothes and improve the washing effect; it can also simplify the operation process: users do not need to add detergent manually, and the washing machine can automatically adjust the amount of detergent added according to the amount of detergent used. This simplifies the user's operation process, reduces cumbersome steps and improves user convenience; for those users who need to add or remove clothes during the washing process, the automatic detergent addition function can avoid the waste of detergent. If the user adds detergent manually, he may add too much or too little because he is not sure about the amount of detergent, which will waste detergent or affect the washing effect; the automatic addition function can replenish according to actual needs to ensure the normal use of detergent and avoid detergent waste.

[0030] Adding the correct amount of detergent during the wash cycle ensures that each wash has the same detergent concentration, providing more consistent washing results. This is especially important for laundry programs that require long running times to ensure that every wash is cleaned to the desired level.

[0056] Obtain the clothing weight change M according to the weighing module b In this embodiment, the weight change of the clothes M b , when you open the door to take out clothes, then M b <0, if you open the door to add clothes in the middle, then M b >0.

[0057] In this embodiment, by judging whether the change in the weight of the clothes is positive or negative, it is possible to distinguish between the operations of opening the door midway to take out clothes and opening the door midway to add clothes, so that corresponding adjustments can be made when replenishing detergent. Detergent is replenished based on the actual change in the weight of the clothes, avoiding the waste of a fixed amount and saving the cost of using detergent.

[0058] According to the change in clothing weight M b Calculate the amount of washing water V that needs to be replenished when adding and / or removing clothes from the washing machine 3 .

[0059] In this embodiment, when clothes are added and / or taken out during the operation of the washing machine, the drainage volume V of the washing water is obtained according to the water level detection module or the weighing module. p .
