The invention relates to the technical field of washing machines, in particular to a drying system, a washing and drying integrated machine and a control method thereof.

Background technique

With the improvement of people's consumption level, people's requirements for quality of life are getting higher and higher. Usually, after washing, the clothes are generally dried by air drying. However, in the season of poor air quality, the clothes that are dried outside are susceptible to secondary pollution by bacteria and dust, which affects people's health. In this case, the laundry drying device or the washing and drying integrated machine is increasingly popular in the market. However, the more common clothes drying devices currently on the market are generally single dryer types, which need to be matched with separate washing machines. For this reason, users need to purchase two different machines and use them together, not only because of their large size. More home space, but also increases the user's purchase cost. At present, the more common washing and drying integrated machine on the market has a small drying capacity, which is generally 50%-60% of the washing capacity, and has to be divided twice when the user washes more clothes. Even more drying is performed. Since the single drying time is generally more than 2 hours, this type of machine not only causes inconvenience to the user, but also causes waste of time for the user.

Based on the above work, one embodiment of the present invention further provides a control method for the foregoing washing and drying integrated machine, comprising the steps of:

S100. After receiving the request to enter the drying mode, detecting an operation mode of the first roller and the second roller;

S200: Perform the following operations according to the detection result:

If the first roller is in the drying mode and the second roller is in the non-drying mode, the communication between the air channel assembly and the first roller is turned on by the air passage control device, and the same is cut off a communication between the air duct assembly and the second roller;

If the first roller is in the non-drying mode and the second roller is in the drying mode, the communication between the air channel assembly and the first roller is cut off by the air duct control device, and is simultaneously turned on. a communication between the air duct assembly and the second roller;

If the first roller and the second roller are both in the drying mode, simultaneously between the air channel assembly and the first roller, the air channel assembly and the device are controlled by the air duct control device The communication between the second rollers;

S300. Control the drying system to perform a drying operation. In other words, the drying assembly 13 and the fan assembly 14 operate.

In an alternative embodiment, the control flow of the control method provided by one of the exemplary embodiments of the present invention is as shown in FIG. 8.

The control method is turned on after at least one of the rollers enters the drying mode, and when at least one of the rollers enters the drying mode, the step S1 is started. Subsequently, the detection of the operating states of the first roller and the second roller is started, that is, step S2 is performed. First, the running state of one of the rollers is detected (for example, the state of the second roller on the upper side is detected first), that is, step S3 is performed. Regardless of whether the operating state of the drum that is first detected is in the drying mode, it is next to detect the operating state of the other drum (for example, to detect the operating state of the first drum on the lower side), that is, step S4 or step S8 is performed separately.

When the detection result is that the second roller is in the drying mode and the first roller is in the non-drying mode, the driving motor of the plate-shaped reversing structure 17 is controlled by the program to adjust the plate-shaped reversing structure 17 to the second state (as shown in the figure). 4), that is, step S10 is performed. At this time, the communication between the duct assembly and the first drum is cut off, the communication with the second drum is turned on, and the second drum is dried.

When the detection result is that the second roller is in the non-drying mode and the first roller is in the drying mode, the driving motor of the plate-like reversing structure 17 is controlled by the program to adjust the plate-shaped reversing structure 17 to the first state (as shown in the figure). 3), that is, step S11 is performed. At this time, the communication between the duct assembly and the first drum is turned on, the communication with the second drum is cut, and the first drum is dried.

When the detection result is that the first roller and the second roller are both in the drying mode, the driving motor of the plate-like reversing structure 17 is controlled by the program to adjust the plate-shaped reversing structure 17 to the third state (as shown in FIG. 5). , that is, step S9 is performed. At this time, the communication between the air passage module and the first roller and the communication between the second roller and the second roller are both turned on, and the first roller and the second roller are both dried.

When the detection result is the above three cases, after the adjustment of the plate-like commutation structure 17 is completed (that is, after the step S9, S10 or S11 is performed), the operation of the drying unit 13 is detected, that is, step S12 is performed. If the detection result is that the drying unit 13 is not running, the drying unit 13 is turned on, that is, step S13 is performed. If the result of the test is that the drying 13 has been run, no operation is performed.

Next, the operation of the fan assembly 14 is detected, that is, step S14 is performed. If the detection result is that the fan assembly is not running, the fan assembly is turned on, that is, step S15 is performed. If the test result is that the fan assembly is already running, no action is taken.

During the entire drying process, the above procedure is repeatedly executed. When the detection result is that both the first roller and the second roller are in the non-drying mode, the drying assembly 13 is closed, that is, step S5 is performed, and the fan assembly 14 is turned off. That is, step S6 is performed. The program ends here, step S7.

With the fan assembly 14 open, the negative ion generator can be selected to be turned on or off.

It will be readily understood by those skilled in the art that the above various alternatives can be freely combined and superimposed without conflict.

It should be understood that the above-described embodiments are illustrative, and not restrictive, and that various modifications may be made by those skilled in the art in light of the details. Equivalent modifications or substitutions are intended to be included within the scope of the appended claims.
