Description

Technical Field

[0001] The present invention belongs to the field of clothing cleaning, and more specifically, relates to a dosing device and a control method for a washing machine. Background Art

[0002] A washing machine is a frequently used household appliance. With the improvement of living standards and the progress of technology, there has emerged a washing machine with a built-in dosing device, which can automatically dose additives. During the laundry process, the dosage of various additives can be precisely controlled, facilitating the use of users and improving the laundry effect.

[0003] For an automatically dosing washing machine, users need to replenish additives into the liquid storage box of the dosing device, and a transparent or semi-transparent plastic window is usually provided on the liquid storage box. Users can observe the liquid level height of the additives in the liquid storage box through this window, so as to judge whether it is necessary to replenish additives without opening the liquid storage box. However, usually, the washing machine is placed in a corner of the home, resulting in poor light around the dosing device. It is very difficult for users to clearly see the liquid level position of the additives and the scale lines on the window through the plastic window, so that users still need to open the liquid storage box or check the additive storage through the display screen of the washing machine, bringing trouble to the use of users.

[0004] In view of this, the present invention is specifically proposed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and provides a dosing device and a control method for a washing machine. By providing a light-emitting component and a light-transmitting display part in the dosing device, after the light emitted by the light-emitting component illuminates the liquid storage cavity, it is then transmitted outside the dosing device through the display part, thereby solving the problem that it is very difficult for users to clearly see the liquid level of the additives through the display part. At the same time, by making the light transmittance of the display part and the scale part different, the lights respectively transmitted by the display part and the scale part have obvious differences, so as to facilitate users to identify the scale part, thereby solving the problem of difficult observation of the scale part.

[0006] To solve the above technical problem, the basic concept of the technical solution adopted by the present invention is: a dosing device, including a liquid storage box with a liquid storage cavity inside for storing additives, a display part provided on the liquid storage box, and a scale part arranged vertically on the display part for indicating the liquid level of the remaining additives. A light-emitting component is provided inside the dosing device. The display part is made of a light-transmitting material, and the scale part and the display part have different light transmittances respectively, so as to emit lights with different luminosities through the display part and the scale part when the light-emitting component emits light.

[0007] Further, the dispensing device is provided with a water box. An installation groove is formed on the front side of the water box, and the liquid storage box is slidably arranged in the installation groove; the display part is arranged on the front side of the liquid storage box, and the light-emitting component is arranged in the installation groove of the water box.

[0008] Further, a handle is arranged on the front side of the liquid storage box, and a through hole is formed on the front surface of the handle; the display part protrudes from the front surface of the liquid storage box, and the end surface of the protruding end of the display part is flush with the front surface of the handle through the through hole.

[0009] Further, the light-emitting component is arranged at the bottom of the installation groove, and the rear side wall of the liquid storage box is made of a transparent or semi-transparent material.

[0010] Further, the display part and the liquid storage box are integrally formed of a light-transmitting material, and the display part forms part of the chamber wall of the liquid storage chamber.

[0011] A control method for a washing machine, the washing machine is provided with a dispensing device as described above; after the washing machine is powered on, the light-emitting component is controlled to start and stop according to the state of the washing machine.

[0012] Further, the washing machine is provided with an openable and closable door; after the washing machine is powered on, it is judged whether the door is opened; if so, the light-emitting component is controlled to be turned on; if not, the light-emitting component is controlled to be turned off.

[0013] Further, the light-emitting component has a variety of different light-emitting modes; the light-emitting component operates in the first light-emitting mode under normal conditions; the washing machine obtains the real-time liquid level height of the additive in the liquid storage chamber, and when the obtained real-time liquid level height is less than or equal to the preset first liquid level height, the light-emitting component is controlled to switch the light-emitting mode.

[0014] Further, a floating member that rises and falls with the change of the detergent liquid level is arranged in the liquid storage chamber of the dispensing device, and the floating member has magnetism; a plurality of Hall sensors are arranged in the dispensing device, and each Hall sensor is respectively arranged at different height positions; after the washing machine is turned on, each Hall sensor is controlled to respectively sense the magnetic field of the floating member, and it is judged whether the position of the Hall sensor where the magnetic field is sensed is higher than the first liquid level height; if so, it is judged that the real-time liquid level height is greater than the preset first liquid level height; if not, it is judged that the real-time liquid level height is less than or equal to the first liquid level height.

[0015] Further, a light-emitting component is respectively arranged on each Hall sensor. After the washing machine is turned on, the light-emitting component arranged on the Hall sensor that senses the magnetic field is controlled to be turned on, and the other light-emitting components are controlled to remain off.

[0016] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: By arranging a light-emitting component and a light-transmitting display part in the dispensing device, after the light emitted by the light-emitting component illuminates the liquid storage cavity, it is then transmitted to the outside of the dispensing device through the display part, so that the user can clearly observe the liquid level of the additive through the display part; at the same time, by making the light transmittance of the display part and the scale part different, the light rays respectively transmitted by the display part and the scale part have obvious differences, making it easier for the user to identify the scale part, so that it is convenient for the user to compare the liquid level with the corresponding scale part to judge the remaining amount of the additive in the liquid storage cavity.

[0017] At the same time, the structure of the present invention is simple, the effect is remarkable, and it is suitable for popularization and use.

Detailed implementation manners

[0029] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0030] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0031] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0032] As Figures 1-7 shown, in the embodiment of the present invention, a dispensing device is introduced, including a liquid storage box 2 with a liquid storage cavity inside for storing additives, a display unit 210 provided on the liquid storage box 2, and a scale unit 220 arranged vertically on the display unit 210 for indicating the liquid level of the remaining amount of additives; a light-emitting component 4 is arranged in the dispensing device, the display unit 210 is made of a light-transmitting material, and the scale unit 220 and the display unit 210 have different light transmittances respectively, so as to emit lights with different brightnesses through the display unit 210 and the scale unit 220 when the light-emitting component 4 emits light.

[0033] With the above settings, by arranging a light-emitting component 4 and a light-transmitting display part 210 in the dispensing device, after the light emitted by the light-emitting component 4 illuminates the liquid storage cavity, it is then transmitted outside the dispensing device through the display part 210. Since the light transmittance of the additive located in the lower part and the air located in the upper part in the liquid storage cavity is different, an obvious bright-dark dividing line will appear between the lights transmitted outside the dispensing device through the two. The position of this dividing line is the liquid level position of the additive, so that the user can clearly observe the liquid level of the additive through the display part 210. At the same time, by making the light transmittance of the display part 210 and the scale part 220 different, the lights respectively transmitted by the display part 210 and the scale part 220 have obvious differences, making it easier for the user to identify the scale part 220, so as to facilitate the user to compare the corresponding scale part 220 with the liquid level and judge the remaining amount of the additive in the liquid storage cavity.

[0034] It should be noted that the additive is a common laundry treatment liquid such as a detergent, a fabric softener, a disinfectant, and / or a water softener.

[0035] In an embodiment of the present invention, the display part 210 is made of a transparent or semi-transparent material.

[0036] In an embodiment of the present invention, the scale part 220 is made of an opaque or semi-transparent material with a light transmittance less than that of the display part 210, so that the light intensity transmitted by the display part 210 is higher, the displayed liquid level line is clearer, and the light at the position of the scale part 220 is darker. The user can directly compare the height of the liquid level line with each scale part 220 and clearly and intuitively know the liquid level situation of the additive in the liquid storage cavity.

[0037] In an embodiment of the present invention, the display part 210 is made of a semi-transparent material, and the scale part 220 is made of a transparent or material with a light transmittance greater than that of the display part 210, so that the scale part 220 is highlighted for the user to easily observe the scale part 220.

[0038] As Figures 1-4 shown, in an embodiment of the present invention, the display part 210 is arranged on a horizontally facing surface of the liquid storage box 2, the inner surface of the display part 210 faces the inside of the liquid storage cavity, and the opposite outer surface faces the outside of the dispensing device, so that the liquid level position of the additive in the liquid storage box 2 is directly mapped on the display part 210 for the user to directly observe.

[0039] In an embodiment of the present invention, each scale part 220 is respectively a horizontally extending strip-shaped convex structure or groove, and each scale part 220 is respectively arranged on the outer or inner surface of the display part 210.

[0040] Preferably, the scale part 220 is integrally formed with the display part 210. The scale part 220 protrudes from the surface of the display part 210, so that the thickness of the scale part 220 is greater, thereby reducing the light transmittance. Further preferably, the scale part 220 is arranged on the outer surface of the display part 210, and a paint with a darker color is printed on the scale part 220, so that the difference between the scale part 220 and the display part 210 is greater, and it is more convenient for the user to observe the liquid level of the additive in the liquid storage cavity.

[0041] In one embodiment of the present invention, the washing machine is a pulsator washing machine. An annular disc seat is arranged on the top opening of the pulsator washing machine. The liquid storage box 2 of the feeding device is fixed on the rear side surface of the inner ring of the disc seat, and the display part 210 is arranged on the front side surface of the liquid storage box 2; the light-emitting component 4 is installed on the chamber wall at the top of the liquid storage cavity, and the light-emitting end of the light-emitting component 4 faces the display part 210 located on the front side correspondingly; preferably, the front end of the liquid storage box 2 protrudes from the inner ring surface of the disc seat, and an additive replenishing port communicating with the liquid outlet cavity is arranged at the top of the protruding end of the liquid storage box 2.

[0042] In another preferred embodiment of the present invention, the feeding device is provided with a water box 1. An installation groove 110 is arranged on the front side of the water box 1, and the liquid storage box 2 is slidably arranged in the installation groove 110; the display part 210 is arranged on the front side of the liquid storage box 2, and the light-emitting component 4 is arranged in the installation groove 110 of the water box 1; by arranging the drawer-type liquid storage box 2, it is convenient for the user to replenish the additive. More importantly, by arranging the display part 210 on the front side of the liquid storage box 2 that can be pulled back and forth, it is convenient for the user to check the storage amount of the additive. In addition, by installing the light-emitting component 4 on the water box 1, while ensuring that the light emitted by the light-emitting component 4 can irradiate the liquid storage cavity, the light-emitting component 4 is far away from the additive, preventing the additive from adhering to the light-emitting end of the light-emitting component 4, resulting in a reduction in the light cover of the light emitted by the light-emitting component 4.

[0043] In the embodiment of the present invention, a handle 3 is arranged on the front side of the liquid storage box 2, and a through hole is arranged on the front side surface of the handle 3; the display part 210 protrudes from the front surface of the liquid storage box 2, and the end surface of the protruding end of the display part 210 is flush with the front side surface of the handle 3 through the through hole; by arranging the handle 3, it is convenient for the user to pull, and by arranging the through hole, the user can observe the display part 210 through the through hole. At the same time, when the light-emitting component 4 is working, the whole handle 3 on the front side of the feeding device is opaque, and only the display part 210 at the through hole can transmit light, forming a strong contrast, making it easier for the user to notice the display part 210.

[0044] In the embodiment of the present invention, the handle 3 is made of an opaque material.

[0045] In the embodiment of the present invention, an additive replenishing port is arranged at the top of the liquid storage box 2 for the user to replenish the additive into the liquid storage cavity, and a flip cover that can be opened and closed is buckled on the additive replenishing port.

[0046] In an embodiment of the present invention, a light-emitting component 4 is provided on the horizontally oriented groove wall and / or the groove bottom of the installation groove 110, and the light-emitting ends of the light-emitting components 4 are respectively oriented towards the liquid storage cavity. At least a part of the side wall of the liquid storage box 2 located between the liquid storage cavity and the corresponding light-emitting component 4 is provided as transparent or translucent; so as to ensure that the light-emitting component 4 can illuminate the liquid storage cavity while isolating the light-emitting component 4 from the additive, and preventing the additive from adhering to the light-emitting component 4.

[0047] In an embodiment of the present invention, the light-emitting component 4 is arranged at the bottom of the installation groove 110, and the rear side wall of the liquid storage box 2 is made of a transparent or translucent material; by arranging the light-emitting component 4 at the rear side of the liquid storage box 2, the light-emitting end of the light-emitting component 4 is made to face the display part 210, thereby improving the light intensity of the light transmitted by the display part 210 and further improving the clarity of the liquid level position displayed by the display part 210.

[0048] In an embodiment of the present invention, the display part 210 and the liquid storage box 2 are integrally formed of a light-transmitting material, and the display part 210 forms a part of the chamber wall of the liquid storage cavity; so that the entire liquid storage box 2 is light-transmitting, making the light emitted by the light-emitting component 4 easier to propagate into the liquid storage cavity and further improving the brightness of the internal environment of the liquid storage cavity.

[0049] In an embodiment of the present invention, the light-emitting component 4 can emit at least white light, and the display part 210 is made of a colorless light-transmitting material; usually, the additive is a liquid with a certain color. If the light-emitting component 4 is set to emit only a specific color of light, such as yellow, green, etc., when the color of the additive is complementary to the color of the light emitted by the light-emitting device, the light absorption rate of the additive may be greatly increased, preventing the light from being normally conducted to the display part 210 and affecting the user's observation. By setting the light to white, the light will not be seriously affected by the color of the additive, thus ensuring that the user can clearly observe the liquid level of the additive.

[0050] In an embodiment of the present invention, a plurality of light-emitting components 4 are arranged in the installation groove 110 in a height direction, and the light-emitting ends of the light-emitting components 4 are arranged parallel to each other.

[0051] As Figures 5-7 shown, in an embodiment of the present invention, a control method for a washing machine is also introduced. The washing machine is provided with a feeding device as described above; after the washing machine is powered on, the light-emitting component 4 is controlled to start and stop according to the state of the washing machine; by turning on the light-emitting device.

[0052] In an embodiment of the present invention, the washing machine being powered on refers to the state after the power cord of the washing machine is electrically connected to the electrical socket in the room, including the standby state of the washing machine and the working state when performing a laundry treatment program.

[0053] In an embodiment of the present invention, the washing machine is provided with an openable and closable door; after the washing machine is turned on, it is determined whether the door is open; if so, the light emitting component 4 is controlled to be turned on; if not, the light emitting component 4 is controlled to be turned off.

[0054] Through the above settings, under normal circumstances, the door will be opened and closed only when the user puts clothes into the washing machine and when the user takes out the washed clothes. That is, after the washing machine executes the washing program and after the washing program is completed, the opening state of the door is detected to specifically remind the user to observe the remaining additive in the liquid storage chamber before and after the washing program through lights, so that the user can clearly understand whether additives need to be supplemented for this washing and whether additives need to be supplemented before the next washing, thereby improving the intelligence of the washing machine.

[0055] In an embodiment of the present invention, the washing machine is a pulsator washing machine, a clothing inlet is provided on the top of the washing machine, a machine door is provided on the clothing inlet, and a feeding device is arranged on a plate seat in the clothing inlet; when the machine door is opened, the user can feed clothing into the washing machine through the clothing inlet, and the user can directly see the feeding device at this time, and at this time, by turning on the light-emitting device, the user can directly observe the remaining amount of additive in the liquid storage chamber, so that the user can judge whether the additive needs to be supplemented; when the machine door is closed, the machine door blocks the clothing inlet, and the user cannot directly see the display unit 210, and the light-emitting device can be turned off.

[0056] In an embodiment of the present invention, the washing machine is a drum washing machine, a clothing delivery port and a mounting port are provided on the front panel of the washing machine, a delivery device is installed behind the mounting port, and the liquid storage box 2 can be drawn out through the mounting port and protrude from the front panel.

[0057] Since some users are accustomed to keeping the door of the washing machine open after washing clothes, so that the moisture in the washing machine can be discharged, to prevent the interior of the washing machine from being damp for a long time and causing mold; if the light-emitting device is kept on, the power consumption of the washing machine in standby mode will increase. The following embodiments are proposed to address the above problems.

[0058] In the embodiment of the present invention, after the washing machine detects that the door is opened, the light emitting component 4 is controlled to be turned on and timed. After the timed time is greater than or equal to the preset waiting time, the light emitting component 4 is turned off.

[0059] In an embodiment of the present invention, an image acquisition module is provided on the washing machine for acquiring an image of the front side of the washing machine; after the washing machine detects that the door is opened, the image acquisition module acquires image information, and the washing machine determines whether there is a user in front of the washing machine based on the image information. If so, the light-emitting component 4 is turned on; if not, the light-emitting component 4 is turned off; the washing machine can automatically control the start and stop of the light-emitting component 4 according to the user's position, thereby further improving the intelligence of the washing machine.

[0060] In an embodiment of the present invention, the light-emitting component 4 has a variety of different light-emitting modes; the light-emitting component 4 operates in the first light-emitting mode under normal conditions; the washing machine obtains the real-time liquid level height of the additive in the liquid storage cavity, and when the obtained real-time liquid level height is less than or equal to the preset first liquid level height, controls the light-emitting component 4 to switch the light-emitting mode.

[0061] Through the above settings, by enabling the light-emitting component 4 to switch the light-emitting mode, when the user sees the first light-emitting mode of the light-emitting component 4, they can know that the remaining amount of the additive in the liquid storage cavity is sufficient without having to seriously look at the display unit 210; when the light-emitting component 4 switches the light-emitting mode, the user can promptly notice that the remaining amount in the liquid storage cavity may be insufficient, and then by observing the display unit 210, they can make a more accurate judgment on the remaining amount of the additive in the liquid storage cavity, making it more worry-free for the user to use the washing machine.

[0062] In an embodiment of the present invention, the light-emitting mode switching includes at least one or a combination of multiple ones among light intensity adjustment, light color switching, switching between constant light and flashing, and adjustment of the flashing frequency.

[0063] In an embodiment of the present invention, a second liquid level height is also preset, and the second liquid level height is lower than the first liquid level height. When the real-time liquid level height is less than the first liquid level height, it is judged whether the real-time liquid level height is greater than or equal to the second liquid level height; if so, controls the light-emitting component 4 to operate in the second light-emitting mode; if not, controls the light-emitting component 4 to operate in the third light-emitting mode.

[0064] Through the above settings, the user can judge the degree of lack of the remaining amount of the additive according to the different light-emitting modes. When the light-emitting component 4 operates in the second light-emitting mode, the remaining amount of the additive is less but higher than the second liquid level height. The user can check whether the stored additive at home is sufficient and judge whether it is necessary to purchase the additive in advance; when the light-emitting component 4 operates in the third light-emitting mode, the remaining amount of the additive is extremely small. The user can understand through the light that the additive needs to be replenished immediately, otherwise it will affect the normal operation of the washing program.

[0065] In an embodiment of the present invention, when the light-emitting component 4 operates in the first light-emitting mode, the emitted light is constant white light; when the light-emitting component 4 operates in the second light-emitting mode, the light-emitting component 4 emits flashing light, and the light color is a color other than white; when the light-emitting component 4 operates in the third light-emitting mode, the light-emitting component 4 emits light with a higher flashing frequency, and the light color is red; by switching the light to red with strong visual impact and high-frequency flashing, the user can more intuitively judge the situation of the remaining amount of the additive, further enhancing the reminder effect of the light on the user.

[0066] In an embodiment of the present invention, a floating member 240 that rises and falls with the change of the detergent liquid level is provided in the liquid storage cavity of the dispensing device. The floating member 240 has magnetism. A plurality of Hall sensors 5 are provided in the dispensing device, and each Hall sensor 5 is respectively arranged at different height positions. After the washing machine is turned on, control each Hall sensor 5 to respectively sense the magnetic field of the floating member 240, and determine whether the position of the Hall sensor 5 where the magnetic field is sensed is higher than the first liquid level height. If so, it is determined that the real-time liquid level height is greater than the preset first liquid level height. If not, it is determined that the real-time liquid level height is less than or equal to the first liquid level height.

[0067] Through the above settings, by providing the magnetic floating member 240, when the liquid level decreases, the magnetic field centered on the floating member 240 also moves downward, resulting in a change in the magnetic field intensity sensed by the Hall sensors 5 located at different heights. It can be determined that the floating member 240 is located between the two Hall sensors 5 with a higher sensed magnetic field intensity. By reasonably distributing each Hall sensor 5, the judgment of the high and low level of the additive liquid level can be realized.

[0068] In an embodiment of the present invention, each Hall sensor 5 is respectively arranged on a horizontally oriented groove wall and / or the groove bottom of the installation groove 110 of the water box 1; and each Hall sensor 5 is vertically arranged from bottom to top, or obliquely arranged from bottom to top in a horizontal direction. Preferably, the detection ends of each Hall sensor 5 are horizontally oriented towards the liquid storage box 2, and each detection end is spaced a certain distance from the water box 1.

[0069] In an embodiment of the present invention, a sleeve portion 230 extending vertically is provided in the liquid storage cavity of the liquid storage box 2. The sleeve portion 230 has a columnar cavity with a vertically extending axis inside. The floating member 240 is movably arranged in the sleeve portion 230, and the sleeve portion 230 is arranged close to the Hall sensor 5. Specifically, each Hall sensor 5 is arranged on the groove bottom of the installation groove 110, and the sleeve portion 230 is arranged close to the chamber wall at the rear side of the liquid storage cavity. Another specific case is that each Hall sensor 5 is arranged on the left or right groove wall of the installation groove 110, and the sleeve portion 230 is arranged close to the left or right chamber wall of the liquid storage cavity.

[0070] In an embodiment of the present invention, a communication port is opened on the peripheral wall at the bottom end of the sleeve portion 230, so that the internal cavity of the sleeve portion 230 is connected to the liquid storage cavity through the communication port.

[0071] In an embodiment of the present invention, a plurality of communication holes are distributed on the peripheral wall of the sleeve portion 230, and the internal cavity of the sleeve portion 230 is connected to the liquid outlet cavity through each communication hole.

[0072] In an embodiment of the present invention, at least three Hall sensors 5 are arranged in the dispensing device, and the second Hall sensor 5 located at the middle position is arranged at the first liquid level height position; when the second Hall sensor 5 and the first Hall sensor 5 located above respectively sense a strong magnetic field, it is determined that the real-time liquid level height is higher than the first liquid level height; when the second Hall sensor 5 and the third Hall sensor 5 located below respectively sense a strong magnetic field, it is determined that the real-time liquid level height is lower than the first liquid level height.

[0073] In an embodiment of the present invention, the installation position of the third Hall sensor 5 is higher than the minimum liquid level height of the liquid storage cavity. When the position of the floating member 240 is lower than the third Hall sensor 5, the second Hall sensor 5 cannot sense the magnetic field of the floating member 240; when only the third Hall sensor 5 senses the magnetic field, it is determined that the real-time liquid level is less than the second liquid level height.

[0074] In an embodiment of the present invention, the installation position of the first Hall sensor 5 is lower than the maximum liquid level height of the liquid storage cavity. When the position of the floating member 240 is higher than the first Hall sensor 5, the second Hall sensor 5 cannot sense the magnetic field of the floating member 240; when only the first Hall sensor 5 senses the magnetic field, it is determined that the liquid storage cavity is in a full liquid state.

[0075] In an embodiment of the present invention, the control method of the washing machine includes:

[0076] S10: When the washing machine is powered on, determine whether the door is opened; if so, execute S20; if not, execute S50;

[0077] S20: Control the lighting component 4 to turn on;

[0078] S30: Determine again whether the door is opened; if so, execute S40; if not, execute S50;

[0085] S22: Control the light-emitting component 4 to operate in the first light-emitting mode, and execute S30;

[0086] S23: Determine whether the real-time liquid level height is greater than the second liquid level height; if so, execute S24; if not, execute S25;

[0087] S24: Control the light-emitting component 4 to operate in the second light-emitting mode, and execute S30;

[0088] S25: Control the light-emitting component 4 to operate in the third light-emitting mode, and execute S30;

[0089] S30: Determine again whether the door body is opened; if so, execute S40; if not, execute S50;

[0090] S40: Determine whether the door opening time is greater than or equal to the waiting time; if so, execute S50; if not, execute S20;

[0091] S50: Control the light-emitting component 4 to turn off.

[0092] In another embodiment of the present invention, S40 can also be replaced with: S40: Control the image acquisition module to acquire the image information on the front side of the washing machine, and determine whether there is a user on the front side of the washing machine according to the image information; if so, execute S20; if not, execute S50;

[0093] In the embodiment of the present invention, a light-emitting component 4 is respectively arranged on each Hall sensor 5. After the washing machine is turned on, control the light-emitting component 4 arranged on the Hall sensor 5 that senses the magnetic field to turn on, and control other light-emitting components 4 to remain off; through the above settings, by controlling the light-emitting component 4 on the corresponding Hall sensor 5 to emit light according to the real-time liquid level, the light sources of each light emission are concentrated around the additive liquid level, achieving an effect similar to a spotlight, mapping the liquid level position of the additive more clearly and conspicuously on the display unit 210. At the same time, the position where the light shines through on the display unit 210 will also change with the rise and fall of the liquid level, and the user can make a preliminary judgment on the approximate position of the liquid level through the light position, further facilitating the user to observe the remaining amount of the additive in the liquid storage cavity.

[0094] In the embodiment of the present invention, after the washing machine is turned on, and when all Hall sensors 5 cannot sense the magnetic field, it is determined that the dispenser box is abnormal, and control the light-emitting component 4 to operate in a preset abnormal light-emitting mode.

[0095] With the above settings, when the liquid storage box 2 is not fully pushed into the water box 1, the distance between the Hall sensor 5 and the floating member 240 is too far, resulting in each Hall sensor 5 being unable to sense the magnetic field respectively. Thus, the washing machine can judge whether the liquid storage box 2 is normally installed through the Hall sensor 5, without the need to additionally provide components for detecting the position of the liquid storage box 2.
