- As shown in
Figures 1 to 9 , the present disclosure provides a washing machine, which includes abox 1. A barrel assembly is provided in thebox 1, and atray 2 is provided on thebox 1. Thetray 2 is provided with aclothes putting port 3, which corresponds to the barrel opening of the barrel assembly. Thetray 2 is also provided with anupper cover 9 for opening and closing theclothes putting port 3. - The washing machine also includes a
water supply assembly 5. Thewater supply assembly 5 is installed on thetray 2 and has a main washing water supply mode and an auxiliary washing water supply mode. In the main washing water supply mode, it is configured to inject water into the barrel assembly, and in the auxiliary washing water inlet mode it is configured to spray water to thelaundry 10 at the clothe putting port 3 (seeFigure 2 ). - The above-mentioned
water supply assembly 5 is not controlled by the preset washing program of the washing machine for the clothes in the washing barrel assembly in the auxiliary washing water supply mode, but is controlled by thedetection device 6. - The present disclosure uses the
water supply assembly 5 of the washing machine as the water outlet structure in the auxiliary washing stage, and controls whether it is started by thedetection device 6. During the local cleaning process, water is sprayed on theclothes 10 to be washed at theclothes putting port 3 to improve local cleaning. The cleaning effect of the position is improved, and the structure of the washing machine is simplified on the basis of increasing the function of the washing machine. - The washing machine also includes an auxiliary
detergent dispensing device 4, which is installed on thetray 2 and used to put detergent onto thelaundry 10 at the clothes putting port 3 (seeFigure 1 ). - The above-mentioned
detection device 6 is also configured to generate a start signal for activating the auxiliarydetergent dispensing device 4 or thewater supply assembly 5 after detecting the signal of the approachinglaundry 10. When no signal from thelaundry 10 is detected nearby, a closing signal is generated to close the auxiliarydetergent dispensing device 4 or thewater supply assembly 5. - Alternatively, the signal for controlling the shutdown of the
detergent dispensing device 4 or thewater supply assembly 5 in the present disclosure can also be manually controlled or voice controlled. The above solution in which thedetection device 6 is configured to control the closing signal of thedetergent dispensing device 4 or thewater supply assembly 5 is only a preferred embodiment and is not a limitation of the detection device of the present disclosure. - It should be noted that the detection device controls the startup and shutdown of the
water supply assembly 5 in the auxiliary washing water supply mode. - In some embodiments of the present disclosure, the washing machine further includes a
control panel 7, which is provided with a program selector and additional function selection buttons. Acontrol panel 7 is provided on thetray 2. In particular, thecontrol panel 7 provided by the present disclosure is provided with acontrol button 8. Thecontrol button 8 is configured to control whether thedetection device 6 generates and starts a start signal of the auxiliarydetergent dispensing device 4 or thewater supply assembly 5. The control panel may also be provided with buttons or knobs to control the auxiliarydetergent dispensing device 4 to stop dispensing detergent or to control thewater supply assembly 5 to stop spraying water. - Specifically, as shown in
Figure 4 , since thewater supply assembly 5 and the auxiliarydetergent dispensing device 4 are both arranged on thetray 2, the user will inevitably pass by thedetection device 6 when putting clothes into the barrel assembly. In order to avoid thedetection device 6 is accidentally triggered, the present disclosure sets acontrol button 8 on thecontrol panel 7. Only when thecontrol button 8 is in the selected state, thedetection device 6 will detect whether there islaundry 10 approaching. Otherwise, thedetection device 6 will not It will detect whether there islaundry 10 approaching. - The above solution makes the washing machine of the present disclosure more logically in the process of controlling the
water supply assembly 5 and the auxiliarydetergent delivery device 4 in the auxiliary washing water supply mode, and reduces the possibility of being accidentally triggered. - In some embodiments of the present disclosure, the
water supply assembly 5 includes a flow rate adjustment unit configured to adjust the inlet water flow rate of the auxiliary washing water supply mode to 40% to 80% of the inlet water flow rate of the main washing inlet flow rate after detecting that thecontrol button 8 is selected. - In detail, the function of the above-mentioned
water supply assembly 5 in the main washing water supply mode is to supply water into the barrel assembly. Therefore, thewater supply assembly 5 may also include a main detergent dispensing device. In the main washing water supply mode, the function is to supply water into the barrel assembly. Use water to dilute the detergent delivered by the main detergent dispensing device or dissolve the washing powder. Therefore, in the main washing water supply mode, the inlet water flow rate of thewater supply assembly 5 is generally larger, on the one hand, to dissolve the washing powder or dilute the detergent, and on the other hand, to reduce the overall time of the washing process. - However, in the auxiliary washing water supply mode, the function of the
water supply assembly 5 is to spray water to thelaundry 10 at theclothes putting port 3 to wet the local position of thelaundry 10. If the water outlet speed is too high, water splashing may occur. And generally, less water is used in local locations, if the water outlet speed is large, it will also cause a waste of water. - Therefore, in some embodiments of the present disclosure, the water outlet speed of the
water supply assembly 5 at different stages is further limited. That is, by setting up the flow rate adjustment unit, when the function of thewater supply assembly 5 is to wet the local position of thelaundry 10, the water outlet speed is adjusted to 40% to 80% of the water outlet speed in the main washing water supply mode. - In a preferred solution, a s water outlet speed selector can also be provided on the
control panel 7 so that the user can determine the water outlet speed. - In some embodiments of the present disclosure, the washing machine further includes a turbidity detection unit, which is disposed in the barrel assembly and used to detect the turbidity of the water in the barrel assembly.
- The washing machine also includes a drainage assembly, which is communicated with the barrel assembly and used to drain water in the barrel assembly.
- At the end of the auxiliary washing water supply mode, when the turbidity of the water in the barrel assembly exceeds the set threshold, the drainage assembly is controlled to open to drain the water in the barrel assembly.
- In detail, the auxiliary
detergent dispensing device 4 is arranged on thetray 2 to put detergent into thelaundry 10 at theclothe putting port 3. Thewater supply assembly 5 is also arranged on thetray 2. It can be seen when cleaning is performed at a local location to thelaundry 10, the barrel assembly is configured to receive the detergent, water or mixed liquid flowing down from thelaundry 10 at theclothes putting port 3. - However, when the degree of dirt in a local location is high, the turbidity of the washing water after cleaning in the local location is high and it is not suitable for being reused for washing other clothes. Therefore, the present disclosure sets a turbidity detection unit in the barrel assembly. When it is detected that the
control button 8 is triggered, before the main water is supplied, the turbidity of the partially cleaned washing water contained in the barrel assembly needs to be detected. When the control unit determines that the turbidity of the washing water in the barrel assembly is relatively high at this time, it controls the drainage assembly to start, and then starts the subsequent washing process after draining the wash water in the barrel assembly. If the control unit determines that the turbidity of the wash water in the barrel assembly is low at this time, it means that this part can be recycled and does not need to be discharged. - The above solution can improve the washing ratio of clothes and prevent water with high turbidity from damaging the
laundry 10. - In a further solution, before the main washing water supply mode starts, when the turbidity of the wash water in the barrel assembly does not exceed the set threshold, the
water supply assembly 5 is controlled to be in the main washing water supply mode. The water inflow amount is the difference between the preset water inflow amount in the selected washing program and the water inflow amount in the auxiliary washing water supply mode. - In detail, the
water supply assembly 5 also includes a flow detection unit. During the auxiliary water inlet stage, the total flow of water is detected. When the turbidity of the washing water in the barrel assembly is low after the local cleaning is completed, the control unit obtains the preset water inflow amount in the washing program of the user's selection and the total water inflow amount of in the auxiliary washing water supply mode. In the main washing water supply mode, the amount of water that thewater supply assembly 5 controls to supply into the barrel assembly should be the difference between the preset water inflow amount in the washing program of the user's selection and the total water inflow amount of in the auxiliary washing water supply mode. - The above solution can avoid accidents such as overflow caused by high water levels in the barrel assembly during the washing process.
- It should be noted that the flow detection unit is only one feasible implementation manner for realizing the above function. In other feasible implementation manners, for example, the above function can also be realized by arranging a water level detection unit in the barrel assembly.
- In some embodiments of the present disclosure, the
water supply assembly 5 also includes a water box, which is arranged on thetray 2, and the water from the water box falls into the barrel opening range of the barrel assembly. - The main detergent dispensing device is used to dispense detergent into the water box quantitatively; before the main washing water supply mode starts, the detergent dispensing amount of the auxiliary
detergent dispensing device 4 is obtained, and according to the amount of detergent dispensed by the auxiliarydetergent dispensing device 4 is adjusted by the amount of detergent dispensed quantitatively by the main detergent dispensing device into the water box. - In detail, the above-mentioned main detergent dispensing device is a detergent delivery device with an automatic delivery function. The main washing water supply mode of the water supply assembly and the main detergent dispensing device deliver detergent are the same with the existing washing machine water inlet puts detergent into the barrel. For example, the main detergent dispensing device includes a liquid storage container, a negative pressure suction unit or a quantitative pump, etc. In the main washing water supply mode, the detergent is automatically put into the water box, and is diluted by the water supply assembly and flushed into the barrel assembly. Inside.
- The detection of washing water in the auxiliary washing process: when the turbidity of the washing water in the barrel assembly is low, this part of the water will be reused. However, part of the detergent has been dissolved in this part of the water, if at this time, the amount of detergent is added according to the preset amount in the washing program selected by the user, the concentration of detergent in the water will be high, resulting in unclean rinsing.
- Therefore, in the present disclosure, before the main washing water supply mode starts, the control unit will obtain the detergent delivery amount of the auxiliary
detergent delivery device 4, and then adjust the main detergent delivery amount according to the detergent delivery amount of the auxiliarydetergent delivery device 4. The detergent dispensing device dispenses a certain amount of detergent into the water box. - For example, the preset automatic detergent dosage in the washing program selected by the user is M, and during the local cleaning process, the detergent dosage of the auxiliary
detergent dispensing device 4 is N, then in the main washing water supply mode, the amount of detergent put into the water box by the main detergent dispensing device is Q=K*(M-N). Among them, K is the adjustment coefficient, which is generally determined by the laboratory after many tests. The value of K is between 1.2 and 1.5. - In some embodiments of the present disclosure, the
detection device 6 alternately generates a start signal for starting thewater supply assembly 5 or the auxiliarydetergent dispensing device 4 with the number of detections. - The
detection device 6 sequentially generates a start signal for starting thewater supply assembly 5, a closing signal for turning off thewater supply assembly 5, a starting signal for starting the auxiliarydetergent dispensing device 4, and a closing signal for closing the auxiliarydetergent dispensing device 4. - In detail, during use, as shown in
Figure 2 , when thedetection device 6 detects the approach of thelaundry 10, it generates a start signal to start thewater supply assembly 5, and sends the start signal to thewater supply assembly 5, after the start signal is received, thewater supply assembly 5 sprays water to wet thelaundry 10 at theclothes putting port 3. When the user determines that the clothes are completely wet, he moves the clothes away from the detection range of thedetection device 6. Thedetection device 6 cannot detect the signal of thelaundry 10 and generates a closing signal to close thewater supply assembly 5, and sends the closing signal to thewater supply assembly 5. After receiving the closing signal, thewater supply assembly 5 stops spraying water. - As shown in
Figure 1 , when thedetection device 6 detects the approach of thelaundry 10 again, it generates a start signal to start the auxiliarydetergent delivery device 4, and sends the start signal to the auxiliarydetergent delivery device 4. After receiving the start signal, the auxiliarydetergent delivery device 4 put detergent into thelaundry 10 at theclothes putting port 3 and apply it on thelaundry 10. When the user determines that an appropriate amount of detergent has been sprayed, thelaundry 10 is moved away from the detection range of thedetection device 6. Thedetection device 6 cannot detect the signal of thelaundry 10 and generates a closing signal to close the auxiliarydetergent dispensing device 4, and sends a closing signal to the washing dispensing device. After receiving the closing signal, the auxiliarydetergent delivery device 4 stops delivering detergent to thelaundry 10 at thelaundry delivery port 3. - At this point, as shown in
Figure 3 , thelaundry 10 is wet and coated with detergent. After the user rubs thelaundry 10 and visually cleans the stains on thelaundry 10, the user brings thelaundry 10 close to thedetection device 6 for inspection again. When thedetection device 6 detects that thelaundry 10 is approaching, it generates a start signal to start thewater supply assembly 5 and sends the start signal to thewater supply assembly 5. After receiving the start signal, thewater supply assembly 5 sprays water to thelaundry 10 again to rinse the detergent foam from thelaundry 10. - After the detergent foam is washed away, the user visually checks whether the stains on the
laundry 10 have been cleaned. If the stains on thelaundry 10 are clean, the user moves thelaundry 10 away from the detection range of thedetection device 6. Thedetection device 6 cannot detect thelaundry 10 and a closing signal is generated to close thewater supply assembly 5, and the closing signal is sent to thewater supply assembly 5. After receiving the closing signal, thewater supply assembly 5 stops spraying water. If it has not been cleaned yet, thelaundry 10 can be brought close to thedetection device 6 again. When thedetection device 6 detects the approach of thelaundry 10 again, a start signal is generated to start the auxiliarydetergent dispensing device 4, and the start signal is sent to the auxiliarydetergent dispensing device 4. After receiving the start signal, the auxiliarydetergent dispensing device 4 puts detergent into thelaundry 10 and applies it to thelaundry 10. When the user determines that an appropriate amount of detergent has been sprayed, thelaundry 10 is moved away from the detection range of thedetection device 6. Thedetection device 6 cannot detect the signal of thelaundry 10 and generates a closing signal to close the auxiliarydetergent dispensing device 4, and sends a closing signal to the washing dispensing device. After receiving the closing signal, the auxiliarydetergent dispensing device 4 stops dispensing detergent to thelaundry 10. - The user can control whether the clothes are close to the
detection device 6 according to the actual situation, so that water spraying and detergent injection can be performed alternately to improve the cleaning effect of local locations. In order to prevent false triggering and determine the accuracy of partial washing of clothes, thedetection device 6 detects that the signal of thelaundry 10 within the detection range reaches the preset time, and then determines that thelaundry 10 needs to be partially washed. At this time, thedetection device 6 generates a start instruction to start thedetergent dispensing device 4 or thewater supply assembly 5. - In the above solution, only one
