The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in fig. 1 to 6, the present invention relates to a control method of a washing and drying all-in-one machine having a waterway structure as described below.
Fig. 1 to 3 show an embodiment of the present invention, and fig. 4 to 6 show another embodiment of the present invention.
As shown in fig. 1 and 4, the washing and drying machine is provided with two drums, an upper drum 1 and a lower drum 2 are arranged in an overlapped manner, the upper drum 1 is provided with an upper water discharge pipeline 11, the lower drum 2 is provided with a lower water discharge pipeline 21, preferably, the upper drum 1 is a drying drum, the lower drum 2 is a washing drum, so that condensed water generated during drying of the upper drum is discharged from the upper water discharge pipeline 11, and washing water generated during washing of the lower drum is discharged from the lower water discharge pipeline 21.
When the upper drum is used for drying, the condenser 12 condenses the moisture in the drying air, the condensed water generated in the condensing process is discharged through the upper water discharging pipeline 11, the condenser 12 is further provided with a condenser filtering device 13, the condenser filtering device 13 needs to be cleaned after filtering, a flushing pipeline 14 is further arranged at the position of the condenser filtering device 13 and used for cleaning the condenser filtering device 13, the flushing pipeline 14 generates flushing water through opening and closing of a flushing valve 141, and the flushing water and the condensed water generated by the flushing pipeline 14 are discharged through the upper water discharging pipeline 11.
When the lower cylinder is used for washing and the generated washing water needs to be drained, the drainage pump 3 arranged below the washing and drying integrated machine can drain the washing water out of the machine body.
The draining pump 3 of the washing and drying integrated machine is provided with a water inlet chamber 31, the water inlet chamber 31 is provided with a plurality of water inlets, the water inlets are respectively connected with different pipelines, and multiple paths of inlet water of the water inlet chamber 31 are discharged out of the machine body through a main draining pipeline 32.
The upper water discharge pipeline 11 of the upper barrel 1 is connected with one water inlet and communicated with the water inlet chamber 31, and the lower water discharge pipeline 21 of the lower barrel is connected with the other water inlet and communicated with the water inlet chamber 31.
The lower cylinder is a washing cylinder, in the washing process, the washing water has foams generated by adding a detergent, and odor generated in the washing process can be diffused to other positions through a pipeline.
Since the drainage of the upper and lower drums 1 and 3 is operated by the same drainage pump 3 and the upper and lower drainage pipes 11 and 21 are communicated with each other by simultaneously communicating the water inlet chamber 31, it is necessary to provide a partition means on the upper drainage pipe 11 to partition the upper and lower drums, and the foam or odor generated from the lower drum is prevented from diffusing to the drying drum through the pipe to contaminate the washed laundry.
The washing and drying integrated machine is also provided with a main control system, and after the isolating device is arranged in the drainage pipeline, the main control system controls the isolating device according to the working states of the upper barrel, the lower barrel and the drainage pump.
Example one
In the present embodiment, the upper drainage pipeline 11 is provided with a water sealing structure 111 to form a water seal to separate the upper cylinder from the lower cylinder.
As shown in fig. 1, a water sealing structure 111 is disposed in the middle of the upper drainage pipeline 11, the water sealing structure 111 is a local bending structure, and liquid is accumulated at the bottom of the local bending structure to block the pipeline, so that gas or foam cannot pass through the pipeline.
Preferably, as shown in fig. 2, the local bending structure is a U-shaped bent pipe, one end of the U-shaped bent pipe extends upwards, the other end of the U-shaped bent pipe is bent downwards again, and liquid can be accumulated at the bottom of the U-shaped bent pipe to form a water seal.
The water seal structure 111 is isolated by accumulating water in the pipeline at the bottom of the elbow, due to the flow generated by the accumulation of condensed water and the action of the drainage pump, part of accumulated water can be pumped away by the water seal structure 111 along with the work of the drainage pump 3, so that residual water in the water seal structure 111 can not form a water seal, the upper cylinder 1 and the lower cylinder 2 can not be isolated, odor and foam enter other positions along with the pipeline, and therefore the main control system needs to supplement water when the water seal mechanism is lack of water.
Since the condenser filter device 13 has the flushing line 14, the flushing line 14 discharges flush water together with condensed water when cleaning the filter device, so that the main control system can control the flushing valve 141 to replenish water to the water seal structure 111.
As shown in fig. 3, the upper cylinder and the lower cylinder have different working states, the main control system has different control methods to perform water replenishing operation on the water seal structure, and the main control system determines the working states of the upper cylinder and the lower cylinder and then performs the following operations:
when the lower barrel works independently, the clothes in the lower barrel are washed, a draining stage and a non-draining stage are provided in the washing process, in the draining stage, accumulated water is contained in the water seal in the upper drainage pipeline 11 to form a water seal, and the drainage pump 3 generates negative pressure after being opened to take away a part of the accumulated water in the water seal structure 111, so that water in the water seal structure is not enough to form the water seal. Therefore, after the washing and draining, the draining pump 3 stops working, and the main control system controls the flushing valve 141 to open to generate flushing water, which flows from the upper draining pipeline 11 to the water sealing structure 111, so as to form water sealing in the water sealing structure again.
The main control system controls the opening time T1 of the flushing valve 141 to replenish water to the water seal structure 111, and ensures that the replenished water can form a water seal within the time T1.
When the upper barrel works independently, the upper barrel can generate condensed water in the drying process, and the condensed water is generated in the whole drying process due to small water amount, so that the condensed water is discharged after being accumulated to a certain water amount in a pipeline, and then the condensed water is discharged by starting the drainage pump 3. When the condensed water is generated, the condensed water is clean water and can enter the lower cylinder 2 through the upper water discharge pipeline 11 to wait for the starting of the water discharge pump 3. When the condensed water is accumulated to a certain amount, the drain pump 3 is opened to drain the condensed water, and at this time, the main control system controls the flushing valve 141 to be opened to generate flushing water to flush the condenser filter device 13.
Since the filter device has the attached matter, when the washing water is washed, the attached matter enters the upper drain line 11 together with the washing water by the washing of the water flow. The washing water at this time cannot be used as the makeup water because it contains the attachments, and the washing water containing the attachments is discharged out of the body together with the condensed water in a state where the drain pump 3 is turned on.
After the drainage of the condensed water is finished and the condenser filtering device 13 is flushed completely, the drainage pump 3 is closed, at this time, the flushing water is clean water, and after the drainage pump 3 stops working, the main control system continues to keep opening the flushing valve 141, so that the flushing water is supplemented into the water seal structure 111 to form a water seal.
After the drainage pump 3 stops working, the main control system continues to keep the flushing valve 141 open for a time T2 to replenish water to the water seal structure 111, and ensures that a water seal is formed at a time T2.
In more complex cases, and in most cases both the upper and lower drums work simultaneously. For convenience of description, the operation state of the lower drum is divided into a draining stage and a non-draining stage, wherein the draining stage is a stage in which the draining is performed in a state in which the draining pump 3 is opened.
At this time, because the condensed water of the upper cylinder is small in water quantity and the washing water of the lower cylinder is large in water quantity, when the upper cylinder and the lower cylinder work simultaneously, the condensed water is discharged together with the washing water in the drainage stage of the lower cylinder, and the washing water is discharged by washing the filtering device simultaneously when the washing water is discharged.
The condensed water generated in the upper drum in the non-drainage stage can directly enter the lower drum to be used as washing water, and the cleanliness of the condensed water does not pollute clothes.
In the non-draining stage, the flushing valve 141 is not opened to ensure that the attachments in the filtering apparatus do not flow into the lower tube to contaminate the laundry.
In the draining stage, the flushing valve 141 is opened, and the washing water, the condensed water and the flushing water are discharged from the body through the drain pump 3 together with the drain main. After the draining stage is finished, the water remaining in the water sealing structure 111 is not enough to form a water seal, and the main control system does not close the flush valve 141, so that clean flush water enters the water sealing structure 111 to form a water seal.
The flushing valve 141 continues to be opened for a time T3 to replenish the water seal structure 111 after the drain pump 3 is closed.
It should be noted that, when the upper cylinder and/or the lower cylinder work, the water replenishing time may be different, and the water replenishing time T1, T2, T3 may be different in different washing and drying integrated machines due to the influence of the arrangement of the drainage pump parameters, the pipe diameter of the drainage pipeline, the volume of the water seal structure, and the like. Under the condition that no water level detection device or the like is arranged, the water replenishing time controlled by the main control system can be determined through testing according to the parameters of the specific washing and drying integrated machine, so that the water sealing structure and the water replenishing process can play corresponding roles in the individual setting difference of the clothes treatment device.
Preferably, the water seal structure 111 is provided with an induction device, and when the residual water amount in the water seal structure 111 is not enough to form a water seal, the main control system controls to replenish water; when the residual water in the water seal structure 111 can still form a water seal, water supplement is not needed, that is, the water seal can still be formed when the lower cylinder works alone, and T1 is 0; when the upper cylinder works alone, water seal can still be formed, and T2 is 0; when the upper cylinder and the lower cylinder work simultaneously, water seal can still be formed, and T3 is 0.
More preferably, the U-shaped elbow is provided with a water level detection device, and the water level detection device feeds back a signal to the main control system when the water level is lower than a set water level, wherein the set water level is a critical water level for forming the water seal.
Example two
The difference between this embodiment and the previous embodiment is that the upper drain pipeline 11 is provided with a drain valve 112, and the main control system controls the on-off of the drain valve 112 according to the working states of the upper cylinder and the lower cylinder to achieve the purpose of isolating the upper cylinder from the lower cylinder.
As shown in fig. 4 and 5, the water seal structure 111 in the first embodiment is replaced by a drain valve 112. The drain valve 112 is closed when it is opened by the condensed water and the washing water in the upper tube 1 and when there is no condensed water and/or washing water passing therethrough to ensure that the foam, odor, etc. of the lower tube 2 are diffused to the upper tube 1.
According to the arrangement of the drain valve 112, the main control system has a control method as shown in fig. 6.
The main control system judges the working states of the upper barrel and the lower barrel, and has the following control method according to the working states of the upper barrel and the lower barrel:
when the main control system detects that the lower barrel works independently, the main control system keeps the drainage valve 112 closed so as to ensure that the upper barrel is not polluted by pollutants generated in the working process of the lower barrel when the upper barrel does not work, and at the moment, the upper barrel 1 and the lower barrel are always kept in an isolated state;
when the main control system detects that the upper barrel works alone, the main control system controls the intermittent opening of the drain valve 112, because the quantity of condensed water is small, the main control system drains water when the condensed water is accumulated to a certain quantity, the main control system opens the drain valve 112 and the drain pump 3 to drain the condensed water, at the moment, the flushing valve 141 is opened as required to clean the condenser filtering device 13, the flushing water is drained at the same time, the flushing valve 141 is closed after the drainage of the condensed water is finished, the drain pump 3 stops working, and the main control system closes the drain valve 112;
when the main control system detects that the upper cylinder and the lower cylinder work simultaneously, the main control system starts the drain valve 112 when the drain pump 3 starts to work, namely, in the drainage stage of the lower cylinder, when the drain pump 3 is started, the main control system starts the drain valve 112 to enable condensed water and/or flushing water generated by the upper cylinder 1 to be drained together with washing water to drain the machine body, and after drainage is finished, the main control system closes the drain valve 112.
Preferably, the drain valve 112 has a pressure sensor, the main control system performs on-off control by a feedback signal of the pressure sensor, and the main control system controls the drain valve 112 to open when the pressure reaches a set value.
In the two embodiments, the washing and drying integrated machine can be arranged in a single cylinder, the single cylinder has washing and drying functions at the same time, and the washing and drying functions have corresponding drainage pipelines; the double cylinders can be arranged in parallel and have the same or different functions, and the isolation of the double cylinders is realized by arranging isolation structures such as a water seal structure or a drain valve; the upper drum can be a washing drum, the lower drum can be a drying drum, and a drainage pipeline of the drying drum is provided with an isolation structure and is correspondingly controlled by a master control system.
The friendship effect of the present invention can be summarized as: the pipeline of the washing and drying integrated machine is provided with a water seal structure or a valve body, so that water and gas for washing and drying can be separated without mutual interference, the washing water is prevented from polluting dried clothes, and the heat efficiency in the drying process is increased; the control method of the washing and drying integrated machine increases the water replenishing process of the water seal structure, ensures that enough water in the water seal structure forms a water seal, and ensures the isolation between the upper cylinder and the lower cylinder; the washing water for washing the filtering device is used as a supplementary water sealing device, so that the filtering device can be cleaned and the water sealing structure can be sealed under the condition that an additional structure of the machine body is not added; the water seal structure is a U-shaped bent pipe, so that the structure is simple and the processing difficulty is small; the drain valve can realize the isolation of the upper cylinder and the lower cylinder through the on-off setting of the master control system, and is easy to realize.
