However, a certain centrifugal force is generated during the rotation of the inner tub 20, and the existence of the centrifugal force causes a part of water in the washing chamber 201 to be adsorbed on the inner wall of the washing chamber 201, that is, the amount of water actually stored in the washing chamber 201 during the rotation of the inner tub 20 is greater than the amount of water actually stored in the washing chamber 201 when the inner tub 20 is in a stationary state, and if water is continuously injected into the washing chamber 201 during the rotation of the inner tub 20, the amount of water adsorbed on the inner wall of the washing chamber 201 is continuously increased, so that not only a large amount of water is wasted, but also a large amount of water is caused to flow into the water storage chamber 101 from the overflow port when the rotation speed of the inner tub 20 is reduced or stops rotating, and the water level in the water storage chamber 101 is increased rapidly, and if two water paths are provided, water can be injected into the washing chamber 201 through the first water path 41, so that the water in the washing chamber 201 can overflow to the water storage chamber 101 from the overflow port, and after reaching the first water level that is less than heating water level L, stop to washing chamber 201 internal water injection, then, rethread second water route 42 directly to washing chamber 201 water injection, until the water level in the water storage chamber 101 reaches heating water level L, from this, can avoid adsorbing too much water on the inner wall of washing chamber 201, when using water wisely, can also avoid the rotational speed of inner tube 20 to reduce or when the stall, a large amount of water gushes to water storage chamber 101 from the overflow mouth, cause the condition of the water level sharp increase in the water storage chamber 101 to take place.
It can be understood that, according to the requirement, the water in the washing chamber 201 may be injected into the washing chamber 201 through the first water path 41, so that the water in the washing chamber 201 can overflow from the overflow port to the water storage chamber 101, and reach the first water level lower than the heating water level L, and then the water is injected into the washing chamber 201 through the first water path 41, so that the water in the washing chamber 201 can continuously overflow from the overflow port to the water storage chamber 101, and simultaneously, the water is injected into the washing chamber 201 through the second water path 42, that is, the water level in the water storage chamber 101 reaches the heating water level L through the mutual matching of the first water path 41 and the second water path 42. Alternatively, the overflow port may not be provided, that is, the water in the washing chamber 201 does not overflow from the overflow port to the water storage chamber 101, and the water is directly injected into the water storage chamber 101 through the water injection assembly 40 until the water in the water storage chamber 101 reaches the heating water level L.
In an embodiment, referring to fig. 1, the water storage cavity 101 is formed at the bottom of the outer tub 10, that is, the bottom of the outer tub 10 is used for storing water, so that the outer tub 10 is only required to be watertight during the water storage process, and the structure of the outer tub 10 is not required to be changed too much, the heating element 30 can be integrated on the existing product, so that the manufacturing process and the mold of the existing clothes processing equipment are not required to be changed, and the assembly process of the heating element 30 is added on the existing assembly line, so that the production cost can be greatly reduced, and the popularization and the use are facilitated. And the second water path 42 is arranged on the top of the outer tub 10, and the water flowing out of the second water path 42 flows into the water storage cavity 101 along the outer circumference of the outer surface of the inner tub 20, so that the length of the second water path 42 can be saved, and the structure of the laundry treating apparatus can be more compact.
It is understood that the second waterway 42 may be disposed at a side portion of the outer tub 10, or the second waterway 42 may be directly communicated with the water storage chamber 101 as long as it is ensured that the water flowing out of the second waterway 42 can flow into the water storage chamber 101.
Further, the heating member 30 is disposed on a side of the water storage chamber 101 away from the overflow port, so that the heating member 30 can be prevented from affecting the water in the washing chamber 201 to overflow to the water storage chamber 101 through the overflow port.
Furthermore, a water outlet 10b is formed in the bottom wall of the water storage cavity 101, and the water in the water storage cavity 101 can be discharged out of the outer barrel 10 through the water outlet 10b, so that long-term water accumulation caused by incomplete water discharge in the water storage cavity 101 is avoided. The drain opening 10b is provided at a side of the water storage chamber 101 away from the heating member 30 to prevent the heating member 30 from blocking the drain opening 10b when draining water.
It should be noted that, under the condition that heating washing is not required, water does not need to be injected into the water storage cavity 101, and washing can be started when the water level in the inner barrel 20 reaches the preset water level.
A second aspect of embodiments of the present application provides a control method of a laundry treating apparatus, including the steps of:

s3: the heating member 30 is controlled to heat the water in the water storage chamber 101, the inner tub 20 through the water in the water storage chamber 101, and the water in the washing chamber 201 through the inner tub 20. That is, the water in the washing chamber 201 and the water in the water storage chamber 101 are separated, the water in the washing chamber 201 is heated by the inner tub 20, rather than by convection with the water in the water storage chamber 101, that is, the washing chamber 201 can hold water, and the laundry treatment apparatus holds the washing water in the washing chamber 201 of the tub 20 during the process of washing laundry, and the inner tub 20 can also be referred to as a non-porous inner tub 20, so as to avoid the problem that dirt is easily stored and taken up due to the fact that the outer tub 10 holds the washing water in the prior art.
According to the control method of the embodiment of the application, in the rotating process of the inner barrel 20, different parts of the inner barrel 20 are in contact with hot water in the water storage cavity 101 in turn, namely the inner barrel 20 and the hot water move relatively, so that the heat transfer efficiency can be accelerated, and the water in the washing cavity 201 can be heated more uniformly; the heating process does not influence the water injection process of the washing cavity 201, the washing cavity 201 can intake water according to normal speed and flow, in the subsequent washing process, the inner barrel 20 exchanges heat with water in the water storage cavity 101 in a large area, the heating is carried out while washing, the heating process does not influence the washing time, the temperature is conveniently adjusted according to actual needs, the washing process can be always kept in a certain temperature range, and constant-temperature washing can be realized.
In an embodiment, the steps S1 and S2 specifically include: the first water path 41 is controlled to fill water into the washing chamber 201 until the water in the washing chamber 201 overflows from the overflow port to the water storage chamber 101 and reaches a first water level. After the water level of the water storage cavity 101 reaches the first water level, the first water path 41 is closed and the second water path 42 is controlled to inject water into the water storage cavity 101 until the water in the water storage cavity 101 reaches the heating water level L. That is to say, first through first water route 41 to wash chamber 201 internal water injection, until the water in wash chamber 201 can overflow to water storage chamber 101 from the overflow mouth, and after reaching the first water level that is less than heating water level L, stop to filling water in wash chamber 201, then, control second water route 42 directly to wash chamber 201 water injection again, until the water level in water storage chamber 101 reaches heating water level L, from this, can avoid adsorbing too much water on the inner wall of wash chamber 201, when the using water wisely, can also avoid the rotational speed of inner tube 20 to reduce or stop rotating, a large amount of water gushes out to water storage chamber 101 from the overflow mouth, cause the condition emergence of the water level sharp increase in water storage chamber 101.
It can be understood that, if necessary, the first water path 41 may be controlled to fill water into the washing chamber 201 until the water in the washing chamber 201 overflows from the overflow port to the water storage chamber 101 and reaches the first water level. After the water level of the water storage cavity 101 reaches the first water level, the first water path 41 is controlled to continuously inject water into the washing cavity 201, that is, the water in the washing cavity 201 is continuously overflowed to the water storage cavity 101 from the overflow port, and meanwhile, the second water path 42 is controlled to inject water into the water storage cavity 101 until the water in the water storage cavity 101 reaches the heating water level L.

injecting water into the washing cavity 201 until the water in the washing cavity 201 can overflow from the overflow port to the water storage cavity 101 and reach a second water level, and stopping injecting water; that is to say, after the water level in the washing chamber 201 reaches a certain water level height, the excess water can overflow into the water storage chamber 101 through the overflow port, and it should be noted that the water level when the excess water can overflow through the overflow port is the target water level for washing in the washing chamber 201, and the water overflowing through the overflow port will cause the water level in the water storage chamber 101 to rise. At the water injection stage that water storage chamber 101 reached the second water level, no other water route gets into in the water storage chamber 101, consequently, when the water level in the water storage chamber 101 reached the second water level, can indirectly learn that the water level in washing chamber 201 has reached the target water level.
After stopping injecting water for the preset time, injecting water into the washing cavity 201 again, and determining that the water level in the water storage cavity 101 reaches the first water level, wherein the first water level is higher than the second water level.
It should be noted that after the laundry is soaked in the washing chamber 201 for a period of time or rotates several times along with the inner drum 20, part of the laundry may "absorb water" slowly, so that the water level in the washing chamber 201 does not reach the standard even if the water level is not drained, that is, the water level is lower than the water level when the water level overflows from the overflow port because part of the laundry "absorbs water" slowly. Therefore, after stopping the water injection for the preset time, water needs to be injected into the washing cavity 201 again, and the water in the washing cavity 201 overflows to the water storage cavity 101 again, so that when the water level in the water storage cavity 101 rises to reach the first water level, the water level in the washing cavity 201 can be known to reach the target water level again, and the water level can reach the standard in the subsequent normal washing process.
It should be noted that the values of the first water level and the second water level are not fixed, but may be variable.
In an embodiment, before the step S2, the control method includes: it is determined that heating is required. The manner of determining that heating is required may be determined according to heating selected by a user, for example, a heating function is separately provided on the laundry treatment apparatus and selected by the user, or a certain washing mode is a heating washing mode, and the system automatically determines that heating is required when the user selects the washing mode, and the like. It should be noted that the step of determining that heating is required may be performed before the washing chamber 201 is filled with water, or may be performed after the washing chamber 201 is filled with water.
In an embodiment, the step S3 includes: and heating the water in the water storage cavity 101 until the water temperature in the water storage cavity 101 reaches a preset temperature, and stopping heating. That is, an upper heating temperature limit is set to prevent overheating.
It will be appreciated that the water in the water storage chamber 101 may not be drained after the heating is stopped, which is advantageous for maintaining the temperature of the water in the washing chamber 201 and preventing the temperature of the water in the washing chamber 201 from dropping too fast. In one embodiment, after stopping heating, the control method further includes: the water in the water storage cavity 101 is discharged to reduce the rotation resistance of the inner cylinder 20 and reduce the energy consumption.
There are various methods for implementing the step S2, as long as it can ensure that the water in the water storage cavity 101 can reach the heating water level L, for example, in an embodiment, the water storage cavity 101 is filled with water with a predetermined volume, and it can ensure that the water in the water storage cavity 101 can reach the heating water level L without other detection means.
Specifically, the water injection and heating process in the embodiment of the present application will be described below.
In the present embodiment, it is determined that heating is required before water is injected into the washing chamber 201; then control first water route 41 to wash chamber 201 water injection, water can follow the overflow mouth overflow to water storage chamber 101 and reach the second water level in wash chamber 201, stop the water injection, specifically, the water level in water storage chamber 101 reaches the second water level, and stop after the water injection preset time, continue to wash chamber 201 water injection once more, make the water level in water storage chamber 101 continuously rise, until the water level in water storage chamber 101 reaches first water level, first water route 41 stops the water injection, then, second water route 42 is controlled again and continues to water storage chamber 101 water injection, until the water level in water storage chamber 101 reaches heating water level L, later control heating member 30 heats the water in water storage chamber 101, after the temperature in water storage chamber 101 reaches preset temperature, stop heating can.
