In some embodiments, the laundry treating apparatus may further have a washing mode in which the tub assembly 10 may be supplied with water through a water supply path different from the steam washing mode, in the washing mode, water introduced into the outer tub 1 may also be introduced into the water storage region 11 in the outer tub 1, and the first heating member 31 may operate in the washing mode to heat the washing water, thereby improving washing efficiency.

When the tub assembly 10 of the embodiment of the present invention is used in a laundry treating apparatus, when the laundry treating apparatus needs to implement a steam washing mode, a water flow (e.g., a water flow from water) may be caused to flow into the outer tub 1 through the water inlet 121 on the outer tub 1 and flow down to the water storage region 11 in the outer tub 1, and the water level of the water storage region 11 may be controlled to be maintained within a set water level range. For example, the water level in the water storage region 11 can be made to be no higher than the lowest point of the rotation track of the inner drum 2, so that the water in the water storage region 11 can be prevented from entering the clothes treatment cavity 21 of the inner drum 2 to wet clothes; for another example, the lowest water level in the water storage region 11 is not lower than the highest position of the first heating member 31, so that the dry-burning phenomenon of at least part of the first heating member 31 can be avoided, the energy utilization rate can be improved, and the safety can be improved. The first heating member 31 is controlled to heat the water in the water storage region 11 to generate steam, and the generated steam can enter the laundry treating chamber 21 through the communication hole 221 to treat the laundry in the laundry treating chamber 21.

It should be noted that the steam washing mode is mainly to perform sterilization, deodorization, ironing, and other care on the laundry in the laundry treatment chamber 21 based on the steam generated by heating, and therefore, in the steam washing mode, it is desirable to prevent the laundry from being wetted by the inflow water as much as possible. It can be understood that if the water flow enters the inner drum 2 to wet the clothes, the clothes care effect is affected. Moreover, since the laundry is wetted, additional drying time may be required to dry the laundry, which affects the laundry care effect, prolongs the laundry treatment time, and increases energy consumption.

When the tub assembly 10 of the embodiment of the present invention is used in a laundry treating apparatus, a water storage region 11 is formed by using a space in the outer tub 1, the first heating member 31 is disposed in the water storage region 11, water in the water storage region 11 is heated by the first heating member 31 to generate steam, the steam sterilizes, deodorizes, irones, etc. the laundry in the inner tub 2, a steam washing mode can be realized without additionally disposing a steam generator, and the structure is simple and compact

Wherein, when the inner cylinder 2 is at any angle position, the water inlet 121 and the communication hole 221 are staggered. No matter where the communication holes 221 are arranged on the inner cylinder 2, no matter whether the inner cylinder 2 rotates or not, the water inlet 121 on the outer cylinder 1 and all the communication holes 221 on the inner cylinder 2 are arranged in a staggered mode, and when the inner cylinder 2 rotates and the inner cylinder 2 rotates to any angle, the water inlet 121 on the outer cylinder 1 and all the communication holes 221 on the inner cylinder 2 are arranged in a staggered mode. When the inner barrel 2 is at any angle position, the water inlet 121 on the outer barrel 1 and all the communication holes 221 on the inner barrel 2 are staggered, so that in the process of supplying water to the water storage area 11 in the outer barrel 1 through the water inlet 121, water flow entering from the water inlet 121 cannot be directly sprayed to the communication holes 221 and enters the inner barrel 2 from the communication holes 221 to wet clothes, or the probability that the water flow entering from the water inlet 121 is directly sprayed to the communication holes 221 and enters the inner barrel 2 from the communication holes 221 to wet clothes can be remarkably reduced, the requirement of steam washing is favorably met, and the steam washing performance of the whole machine is improved.

Here, the "water inlet 121 and the communication hole 221 are staggered" means that the water inlet 121 and the communication hole 221 are not facing each other and are completely staggered in a direction parallel to a central axis of the water inlet 121.

According to the tub assembly 10 of the embodiment of the present invention, the water storage region 11 is formed by using the space in the outer tub 1, the first heating member 31 is disposed in the water storage region 11, the water in the water storage region 11 is heated by the first heating member 31 to generate steam, the steam is used for performing sterilization, deodorization, ironing and other care on the clothes in the inner tub 2, the steam washing mode can be realized without additionally disposing a steam generator, and the structure is simple and compact; in addition, by optimally designing the relative positions of the communication hole 221 on the inner barrel 2 and the water inlet 121 on the outer barrel 1, water can be reduced or prevented from entering the inner barrel 2 in the process of supplying water to the water storage area 11, so that the wetting of clothes is reduced or avoided in the steam washing mode, the requirement of steam washing is favorably met, and the steam washing performance of the whole machine is improved.

According to some embodiments of the present invention, referring to fig. 2, 3, 5 and 7, a rear wall of the tub 1 in an axial direction is a tub rear wall 12, and the water inlet 121 may be formed on the tub rear wall 12. By disposing the water inlet 121 on the tub rear wall 12, water flows from the rear side of the tub 1 into the tub 1, which can more effectively reduce the water flowing from the water inlet 121 from entering the drum 2 to wet the laundry.

According to some alternative embodiments of the present invention, referring to fig. 1 to 7, the rear wall of the inner cylinder 2 in the axial direction is the inner cylinder rear wall 22, the inner cylinder rear wall 22 may be formed with a plurality of communication holes 221, the outer cylinder 1 rotates relative to the inner cylinder 2 when the inner cylinder 2 rotates, so that the locus swept by the projection of the water inlet 121 on the inner cylinder rear wall 22 in the axial direction of the inner cylinder 2 may be formed as an annular region, which may be a water inlet annular region, and at least a part of the communication holes 221 on the inner cylinder rear wall 22 is located radially inside the water inlet annular region. For example, a part of the communication holes 221 in the inner cylinder rear wall 22 may be located radially inward of the water inlet annular region, or all of the communication holes 221 in the inner cylinder rear wall 22 may be located radially inward of the water inlet annular region. This can further effectively reduce the water flowing from the water inlet 121 from entering the drum 2 to wet the laundry.

In some embodiments of the present invention, referring to fig. 1 to 7, the water inlet 121 may be disposed adjacent to an outer circumferential edge of the tub rear wall 12. Thus, by disposing the water inlet 121 at a position adjacent to the outer circumferential edge of the tub rear wall 12, it is possible to better ensure that the structural strength of the tub 1 satisfies the use requirements, compared to disposing the water inlet 121 at a position adjacent to the center of the tub rear wall 12.

In some embodiments of the present invention, referring to fig. 1 to 7, the water inlet 121 may be located above a central axis of the tub rear wall 12. This may make the position of the water inlet 121 higher, and when the laundry treating apparatus is in the washing mode, since the water level in the outer tub 1 is higher, it may be better to prevent the washing water in the outer tub 1 from flowing to the outside of the outer tub 1 through the water inlet 121 in the washing mode.

Alternatively, the water inlet 121 may be located obliquely above the central axis of the tub rear wall 12. This can prevent the washing water in the outer tub 1 from flowing to the outside of the outer tub 1 through the water inlet 121 in the washing mode, and facilitate the installation of components (such as the below-described connector 40 and the drying tunnel assembly 60) connected to the water inlet 121, resulting in a compact overall structure.

For example, in the specific example of fig. 4 to 7, the tub assembly 10 includes the above-mentioned outer tub 1, inner tub 2, and first heating members 31, the outer tub peripheral wall 14 of the outer tub 1 is recessed downward to form at least a part of the water storage region 11, the first heating members 31 are disposed in the water storage region 11, a water inlet 121 is formed on the outer tub rear wall 12 of the outer tub 1, the water inlet 121 is substantially rectangular and the water inlet 121 extends along the circumferential direction of the outer tub 1, and the water inlet 121 is located obliquely above the central axis of the outer tub 1 and adjacent to the outer peripheral edge of the outer tub rear wall 12. The inner cylinder rear wall 22 is formed with a plurality of communication holes 221, and the plurality of communication holes 221 are all located radially inside the above-described water inlet annular region. The plurality of communication holes 221 are divided into two groups and the two groups of communication holes 221 are arranged at intervals along the radial direction, each group includes the plurality of communication holes 221, and the plurality of communication holes 221 in each group are arranged at intervals along the circumferential direction of the inner cylinder 2 and are arranged in an annular shape. In the steam washing mode, water introduced into the tub 1 from the water inlet 121 flows into the water storage region 11 of the tub 1, the first heating member 31 heats the water in the water storage region 11 and generates steam, and the steam enters the drum 2 through the plurality of communication holes 221 to perform a high temperature treatment on the laundry.

As shown in fig. 1 to 9, a laundry treating apparatus according to an embodiment of the second aspect of the present invention includes: a bowl assembly 10, a first water supply line 50 and a controller, the bowl assembly 10 being a bowl assembly 10 according to an embodiment of the first aspect of the present invention described above. The laundry treating apparatus includes a cabinet in which the tub assembly 10 is disposed.

The first water supply line 50 is connected to an external water source (e.g., tap water), and a water supply valve may be disposed on the first water supply line 50, and the on/off state of the water supply valve controls whether the first water supply line 50 is connected to the external water source. The water supply valve is used to open and close the first water supply pipeline 50, and the water flowing into the first water supply pipeline 50 can flow into the outer tub 1 through the water inlet 121 of the outer tub 1, thereby supplying water to the water storage region 11. When the water supply valve is opened, the first water supply pipeline 50 is conducted, and the water flowing into the first water supply pipeline 50 flows into the outer barrel 1 through the water inlet 121 on the outer barrel 1; when the water supply valve is closed, the first water supply line 50 is cut off, and the water supply to the water storage 11 in the outer tub 1 through the water inlet 121 is stopped.

The controller is used to control the water supply valve based on the water level in the water storage region 11 in the steam washing mode, for example, the water level in the water storage region 11 may be controlled to be kept within a set water level range, for example, the water supply valve is controlled to be closed when the water level in the water storage region 11 reaches a maximum set value, and the water supply valve is controlled to be opened when the water level in the water storage region 11 is lower than a minimum set value. When the water level in the water storage region 11 is within the set water level range, the controller controls the first heating member 31 to heat the water in the water storage region 11 to generate steam, and the generated steam can enter the laundry treatment chamber 21 through the communication hole 221 to treat the laundry in the laundry treatment chamber 21.

It can be understood that, when the inner drum 2 rotates, at least a part of the water flowing into the outer drum 1 from the water inlet 121 is ejected by the inner drum rear wall 22 in a rotating state, so as to reduce the possibility that the water flows into the clothes treatment chamber 21 from the communication hole 221, thereby reducing the possibility that the water flows wet the clothes in the clothes treatment chamber 21. Furthermore, during the rotation of the inner drum 2, the water inlet 121 projects on the inner drum rear wall 22 along the axial direction of the inner drum 2 to sweep a substantially annular region, which is a water inlet annular region, and the inner drum 2 is not provided with the communication hole 221 corresponding to the water inlet annular region, so that the water flow flowing into the outer drum 1 from the water inlet 121 is blocked by the inner drum rear wall 22 and does not pass through the communication hole 221 directly even if the water flows towards the inner drum rear wall 22 at a high speed, and thus the possibility that the water flow of the water inlet 121 enters the laundry treatment chamber 21 can be reduced, thereby reducing the possibility that the water in the steam washing mode wets the laundry in the laundry treatment chamber 21.

The above-mentioned set water level range can satisfy the safety water level required by the first heating member 31 to prevent the first heating member 31 from burning dry to damage itself and peripheral devices, and the set water level range can prevent the water in the water storage region 11 from entering the inner tub 2 to wet the clothes. For example, the set water level range may be higher than the highest position of the first heating member 31 and lower than the lowest point of the rotation track of the drum 2, so that the water level of the water storage region 11 is at a safe water level during the heating process of the first heating member 31.

In some embodiments, the laundry treating apparatus further comprises: the low level sensor 32 and the high level sensor 33, and the low level sensor 32 and the high level sensor 33 are used to detect the water level in the water storage region 11. Wherein, the low liquid level sensor 32 and the high liquid level sensor 33 are both arranged on the outer barrel rear wall 12; the high level sensor 33 has a detected water level higher than that of the low level sensor 32 and lower than the lowest point of the rotation trajectory of the inner tub 2, and the low level sensor 32 has a detected water level higher than the highest position of the first heating member 31. Low level sensor 32 and high level sensor 33 all are connected with the controller communication, and low level sensor 32 and high level sensor 33 send detecting signal, and whether the water level in controller discernment water storage district 11 is suitable according to detecting signal.

The installation positions of the low liquid level sensor 32 and the high liquid level sensor 33 are not limited, and for example, referring to fig. 8, the low liquid level sensor 32 and the high liquid level sensor 33 are both disposed on the tub rear wall 12. On the one hand, it is convenient to mount from the rear side of the tub rear wall 12, and on the other hand, it is also convenient to centrally arrange the electric wires of the low level sensor 32, the high level sensor 33, and the first heating member 31 at the rear side of the tub rear wall 12.

The specific type of the low level sensor 32 is not limited as long as it can detect the water level; the specific type of the high level sensor 33 is not limited as long as the water level can be detected.

In some embodiments, the controller controls the operation state of the water supply valve based on the water level of the water storage region 11, including:
