Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

In the present invention, unless otherwise indicated, terms of orientation such as "upper, lower, top, bottom" are used generally with respect to the orientation shown in the drawings or with respect to the component itself in the vertical, upright or gravitational direction; also, for ease of understanding and description, "inner and outer" refers to inner and outer relative to the profile of each component itself, but the above-mentioned orientation terms are not intended to limit the present invention.

The invention provides a washing machine and an operation method thereof in order to solve the problem of single function of the washing machine in the prior art.

First, a structure of the washing machine will be described.

As shown in fig. 1 to 6, the washing machine is mainly composed of a top cover assembly, an electric box part, a water pump part, a drum part, a water inlet box 60, a door assembly, a frame assembly, and a solvent box 10 part.

As shown in fig. 1 to 4, the washing machine includes a solvent cartridge 10, an ultrasonic generator 20, and an aromatic liquid exhaust pipe 30, the solvent cartridge 10 having a detergent tank 11 and an aromatic liquid tank 12 independent of each other, the ultrasonic generator 20 being connected to the aromatic liquid tank 12 through an aromatic liquid inlet pipe 21, the ultrasonic generator 20 being communicated with an inner cylinder 40 through the aromatic liquid exhaust pipe 30.

When the clothes washing machine is used, the fragrance liquid is added into the fragrance liquid tank 12, and the direction entering function of the washing machine is realized in a manual or automatic mode, so that the clothes are subjected to fragrance treatment, the clothes are fragrant after being washed, and the experience of a user is improved.

The invention adds the aromatic liquid tank 12 to enable the user to add the corresponding aromatic liquid according to own hobbies, thereby meeting the diversified demands of the user. The mode that the detergent tank 11 and the aromatic liquid tank 12 are independently separated can effectively avoid the mixing of the aromatic liquid and the detergent, and ensures that the washing function and the aromatic function are mutually independent.

The washing machine of the present invention has not only an odor removing function but also an aromatic function, converts the diluted aromatic liquid into aromatic vapor through the ultrasonic generator 20, and transfers the vapor to the inner tub 40 of the washing machine, so that laundry is sufficiently contacted with the aromatic vapor.

The washing machine of the present invention further includes a water inlet box 60, and the water inlet box 60 has a first water tank and a second water tank independent from each other, the first water tank corresponding to the detergent tank 11, and the second water tank corresponding to the fragrance liquid tank 12. Thus, the second water tank can store water independently, so that the water in the second water tank can dilute the aromatic liquid in the aromatic liquid tank 12, and the independence of the aromatic function and the washing function is ensured.

As shown in fig. 4, the bottoms of the first water tank and the second water tank each have a plurality of water outlets 61. Water is sprayed into the detergent tank 11 and the fragrance liquid tank 12 through the water outlet holes 61, so that the detergent or the fragrance liquid can be quickly diluted.

In order to ensure that the washing and fragrance are not interfered with each other, the water inlet box 60 has a first water inlet pipe and a second water inlet pipe independent of each other, an outlet of the first water inlet pipe is communicated with the first water tank, and an outlet of the second water inlet pipe is communicated with the second water tank. Similar to the design of the water inlet box 60, the first water inlet pipe and the second water inlet pipe are separated, so that the first water inlet pipe and the second water inlet pipe correspond to the first water tank and the second water tank respectively, water can be stored in the two water tanks independently, and the independence of the washing function and the fragrance function is ensured.

In order to improve the automation degree of the washing machine, the second water inlet pipe is provided with an aromatic liquid inlet valve 62, the washing machine further comprises a liquid level sensor, the liquid level sensor detects the liquid level height in the ultrasonic generator 20, and when the liquid level sensor detects that the liquid level in the ultrasonic generator 20 is lower than the lower limit value, the aromatic liquid inlet valve 62 is opened; when the liquid level sensor detects that the liquid level in the ultrasonic generator 20 is higher than or equal to the upper limit value, the fragrance liquid inlet valve 62 is closed. A liquid level sensor is added in the ultrasonic generator 20 to intelligently remind the user of adding the aromatic liquid, so that the reliable operation of the aromatic function is ensured.

The washing machine of the present invention further includes a panel assembly having a display screen 70, the display screen 70 being connected to the liquid level sensor, and the display screen 70 alarming when the liquid level sensor detects that the liquid level in the ultrasonic generator 20 is lower than the lower limit value. After the user sees the alarm prompt, the fragrance liquid should be added into the fragrance liquid tank 12 in time to ensure that fragrance is sufficient and the clothes are fully aromatherapy.

In order to improve the operability of the fragrance function of the washing machine, the washing machine further includes a panel assembly connected to the ultrasonic generator 20 to control the operation time of the ultrasonic generator 20. Thus, by adjusting the operating time of the ultrasonic generator 20, the intensity of the fragrance can be adjusted to meet the individual needs of different users.

As shown in fig. 1, the washing machine further includes a fragrance liquid drain pipe 50 and a door assembly, a first end of the fragrance liquid drain pipe 50 is connected to the ultrasonic generator 20, and a second end of the fragrance liquid drain pipe 50 is connected to a door seal 41 of the door assembly. The gate seal 41 is provided with a drain hole, and the solution in the ultrasonic generator 20 flows to a drain pump below through the aromatic liquid drain pipe 50, the gate seal 41 and the drain hole, so that the aromatic liquid is discharged out of the washing machine. Therefore, the washing machine can be used as a washing link of the washing machine, and can also be used for replacing new aromatic liquid, so that odor tainting is avoided.

Specifically, the fragrance liquid drain pipe 50 is provided with a fragrance liquid drain valve. The practical emission of the aromatic liquid is controlled through the aromatic liquid drain valve, so that the intelligent degree of the washing machine is improved.

Next, an operation method of the washing machine is described according to the automatic mode, the manual mode, and the fragrance liquid mode.

1. Automatic mode

As shown in fig. 5, after the washing machine is dehydrated, the fragrance function is automatically entered and the ultrasonic generator 20 of the washing machine is operated.

In order to improve the reliability of the automatic operation of the washing machine, the washing machine weighs the laundry in the inner tub 40 after the washing machine is dehydrated and before the washing machine automatically enters the fragrance function to determine the operation time of the ultrasonic generator 20. Since the washing machine can intelligently control the time of adding the fragrance according to the weight of the laundry, that is, the operation time of the ultrasonic generator 20, the operation complexity is reduced.

In order to make the fragrance vapor fully contact with the laundry, the drum 40 of the washing machine is rotated after the washing machine enters the fragrance function. Alternatively, the inner barrel 40 need not rotate rapidly, but rather can rotate only at a low speed. The rotation speed is basically the same as the rotation speed during washing, and can be slightly slower than the rotation speed during washing.

When the washing machine enters the fragrance function, a liquid level sensor of the washing machine detects the liquid level height in the ultrasonic generator 20, and when the liquid level is lower than a lower limit value, a fragrance liquid inlet valve 62 corresponding to a fragrance liquid tank 12 of the washing machine is opened and filled with water; when the liquid level is higher than or equal to the upper limit value, the aromatic liquid inlet valve 62 is closed and water injection is stopped. Thus, the problem of discounting the fragrance function due to too little fragrance liquid in the ultrasonic generator 20 is effectively avoided.

When the liquid level is below the lower limit, a display screen 70 of the panel assembly of the washing machine alarms. At this time, the user should add the fragrance liquid to the fragrance liquid tank 12 in time to ensure sufficient fragrance.

2. Manual mode

Of course, it is also possible to operate manually, the user manually selecting to enter the fragrance function, and the ultrasonic generator 20 is operated.

By operating the panel assembly of the washing machine, the operation time of the ultrasonic generator 20 is set. The user can adjust the color of the fragrance by adjusting the operation time of the ultrasonic generator 20 according to his/her own needs. Generally, the longer the operation time of the ultrasonic generator 20, the more aromatic.

3. Aromatic liquid replacement mode

Considering that the user's demand for fragrance is not constant. The operation method of the present invention further includes a fragrance liquid replacement step, in which a fragrance liquid drain valve of the washing machine is opened, and the fragrance liquid in the ultrasonic generator 20 flows to a door seal 41 of the washing machine through a fragrance liquid drain pipe 50. At this point, the fragrance liquid is drained to ensure that a user can add new fragrance liquid into fragrance liquid tank 12.

Referring to fig. 6, in order to ensure that there is no residual fragrance liquid, the operation method further includes a fragrance liquid flushing step, wherein the fragrance liquid inlet valve 62 corresponding to the fragrance liquid tank 12 of the washing machine is opened and filled with water, and the fragrance liquid drain valve is kept open until the fragrance liquid inlet valve 62 and the fragrance liquid drain valve are closed after the flushing is completed. After the aromatic liquid flowing into the drain pump of the washing machine from the aromatic liquid drain pipe 50 through the gate seal 41 reaches the drain water level, the drain pump is started until the aromatic liquid is discharged, and then the aromatic liquid flushing step is repeated for N times, wherein N is an integer and is greater than or equal to 1. Thus, the newly injected aromatic liquid is not mixed with the residual aromatic liquid, and the reliability of odor tainting is reduced.

The following description will be made according to the specific case of use.

1. First use

When the fragrance function is used for the first time, fragrance liquid is placed in the fragrance liquid tank 12 in advance, after the washing machine is started, the fragrance liquid inlet valve 62 corresponding to the fragrance liquid tank 12 of the washing machine is opened and water is injected, the fragrance liquid in the fragrance liquid tank 12 is diluted by water and flows into the ultrasonic generator 20 until the liquid level sensor of the washing machine detects that the liquid level in the ultrasonic generator 20 is higher than or equal to the upper limit value, and the fragrance liquid inlet valve 62 is closed and water injection is stopped.

After the washing machine finishes dewatering, the washing machine detects the weight of clothes, the ultrasonic generator 20 starts to convert the aromatic liquid into aromatic gas according to the time of entering the aromatic function by weight control, the aromatic gas enters the door seal 41 along the aromatic liquid exhaust pipe 30 and then enters the inner cylinder 40, the inner cylinder 40 rotates at a low speed to loosen the clothes, and the air-immersed aromatic smell is fully contacted with the clothes, so that the intelligent control of the clothes is realized, and the aromatic smell is quickly and fully added.

2. Secondary use

When the user uses the fragrance function for the second time, without adding the fragrance liquid, if the user wants to change the shade degree of the default fragrance, the running time of the ultrasonic generator 20 can be automatically adjusted, and then the start key is pressed, and the liquid level sensor detects the liquid level in the ultrasonic generator 20 (the liquid level sensor is arranged in the ultrasonic generator 20, and the signal of the liquid level sensor controls the fragrance liquid inlet valve 62 corresponding to the fragrance liquid tank 12). If the level of the aromatic liquid in the ultrasonic generator 20 is within the normal range, the aromatic liquid inlet valve 62 does not feed water; if the liquid level is lower than the lower limit value, the liquid level sensor sends out a signal, the display screen 70 reminds the user to add the aromatic liquid in the aromatic liquid tank 12, when the washing machine is restarted, the aromatic liquid inlet valve 62 is filled with water until the liquid level of the ultrasonic generator 20 reaches the upper limit value, the liquid level sensor sends out a signal again to control the aromatic liquid inlet valve 62 to be closed, and the washing machine is in an aromatic functional mode after the water is removed (or directly enters), so that the automatic addition of aromatic smell is realized.

3. Replacement aromatic liquid

As shown in fig. 6, when the user wants to change another fragrance liquid, the user selects a procedure of changing the fragrance liquid, presses a start key, opens a fragrance liquid drain valve, and discharges the old fragrance liquid in the ultrasonic generator 20 to the door seal 41. After the old aromatic liquid is discharged, the old aromatic liquid remaining in the ultrasonic generator 20 is thoroughly washed away by the inflow of the aromatic liquid inlet valve 62, the old aromatic liquid is discharged from the water outlet of the door seal 41 to the outer cylinder and then flows to the drain pump, after the drain pump detects that the liquid level reaches a proper level, the drain pump starts to discharge the old aromatic liquid to the outside, after the drain pump discharges the liquid, the above process is operated once again, and after the drain pump discharges the old aromatic liquid, the drain pump and the aromatic liquid drain pipe 50 are automatically closed, thereby realizing the replacement of the aromatic liquid.
