The water discharge pipe 31 can be used for multiple purposes, and the outlet of the water discharge pipe 31 is closed in the water filling stage; the front loading washing machine may discharge water out of the front loading washing machine through the drain pipe 31 during the draining stage. In this embodiment, the air chamber 51 is communicated with the drain pipe 31, and the existing outer tub 10 may be used without opening the side wall of the outer tub 10.
In one embodiment, referring to fig. 1 and 2, the front-loading washing machine includes a heating element 30 disposed in a water storage chamber 101, and a part of the inner drum 20 extends into the water storage chamber 101; the heating member 30 heats the water in the water storage chamber 101 to heat the inner tub 20 by the water in the water storage chamber 101 and to heat the water in the washing chamber 201 by the inner tub 20. When heating washing is needed, the water in the water storage cavity 101 is heated by the heating element 30, the water in the water storage cavity 101 heats the inner barrel 20, the temperature of the inner barrel 20 is increased, and the inner barrel 20 further heats the washing water in the washing cavity 201, so that the washing water in the washing cavity 201 can be indirectly heated.
The front-opening washing equipment of the embodiment can realize the heating of the washing water only by arranging the heating element 30 between the outer barrel 10 and the inner barrel 20, has simple structure and is easy to realize; the water in the water storage cavity 101 and the washing water in the washing cavity 201 are separated, and the water in the water storage cavity 101 does not pollute the washing water in the washing cavity 201, so that the clothes are washed more hygienically; in the rotating process of the inner cylinder 20, different parts of the inner cylinder 20 are contacted with hot water in the water storage cavity 101 in turn, so that the heat transfer efficiency is accelerated, and water in the washing cavity 201 can be heated more uniformly; the heating process of the water in the water storage cavity 101 does not affect the water injection process of the washing cavity 201, and the washing cavity 201 can feed water at 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, washing and heating are carried out simultaneously, the washing time is not influenced in the heating process, the temperature can be conveniently adjusted according to actual requirements, the temperature can be always kept in a certain temperature range in the washing process, and constant-temperature washing can be realized.

The purpose of the two water paths is that, in actual use, when the washing chamber 201 is filled with water, the inner tub 20 starts to rotate in the outer tub 10, so that the laundry in the washing chamber 201 can sufficiently absorb the water in the washing chamber 201. 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 42, 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 L1 lower than the second water level L2, stopping filling water into the washing chamber 201, and then directly filling water into the washing chamber 201 through the second water path 43 until the water level in the water storage chamber 101 reaches the second water level L2, thereby preventing excessive water from being adsorbed on the inner wall of the washing chamber 201, saving water, and simultaneously preventing a large amount of water from flowing into the water storage chamber 101 from an overflow port to cause a rapid increase of the water level in the water storage chamber 101 when the rotation speed of the inner barrel 20 is reduced or the rotation is stopped.
It should be noted that, in this embodiment, when the water level in the water storage chamber 101 reaches the first water level L1, it indicates that the water level in the washing chamber 201 reaches the preset water level, and when the water level in the water storage chamber 101 reaches the second water level L2, it indicates that the water level in the washing chamber 201 reaches the water level required for heating.
It can be understood that, according to the requirement, water may be injected into the washing chamber 201 through the first water path 42 to enable water in the washing chamber 201 to overflow from the overflow port to the water storage chamber 101, and reach the first water level L1 lower than the second water level L2, and then water may be injected into the washing chamber 201 through the first water path 42 to enable water in the washing chamber 201 to overflow from the overflow port to the water storage chamber 101, and water may be injected into the washing chamber 201 through the second water path 43, that is, the water level in the water storage chamber 101 may reach the second water level L2 through the cooperation of the first water path 42 and the second water path 43.
In an embodiment, referring to fig. 1 and 2, 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, the assembly process of the heating element 30 is added on the existing assembly line, 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.

A second aspect of the embodiments of the present application provides a method for controlling a front loading type laundry device, referring to fig. 3, including the following steps:
s1: water is injected into the washing chamber 201. Water in the washing cavity 201 can enter the water storage cavity 101 through an overflow port on the washing cavity 201; in the process of washing clothes, the front-opening washing equipment contains washing water in the washing cavity 201, and the inner barrel 20 can also be called as a non-porous inner barrel 20, so that the problem that dirt and dirt are easily stored and taken due to the fact that the outer barrel 10 contains the washing water in the prior art can be solved. Before the water level in the washing chamber 201 does not reach the preset water level, the water level in the washing chamber 201 continuously rises, and after the water level in the washing chamber 201 reaches the preset water level, redundant water overflows through the overflow port.
S2: it is judged whether the water level in the washing chamber 201 reaches a preset level according to the water level in the water storage chamber 101. That is, in the water filling stage, it can be indirectly determined whether the water level inside the washing chamber 201 reaches the preset water level according to the water level in the water storage chamber 101.
Specifically, before the washing chamber 201 is filled with water, the current water level in the water storage chamber 101 can be detected by the detection device 50; after the water injection is started, before the water level in the washing cavity 201 does not reach the preset water level, the detection results of the detection device 50, which are used for representing the water level, are the same; after the water level in the washing chamber 201 reaches the preset water level, the excessive water overflows to the water storage chamber 101 through the overflow port, resulting in the water level change in the water storage chamber 101, and the detection device 50 sends out the detection result corresponding to the changed water level. At the water filling stage of the washing chamber 201, no other water path enters the outer tub 10, so that the water level in the washing chamber 201 can be judged to reach the preset water level by comparing the front and rear detection results and knowing that the water enters the water storage chamber 101 from the overflow port. It can be understood that, before the washing chamber 201 is filled with water, if there is no water in the water storage chamber 101, the water level in the water storage chamber 101 is 0 at this time.

Further, step S1 specifically includes:
injecting water into the washing cavity 201 until the water level in the water storage cavity 101 reaches a third water level, and stopping injecting water, wherein the water level in the washing cavity 201 can be judged to reach a preset water level;
after the water injection is stopped for the preset time, water is injected into the washing cavity 201 again until the water level in the water storage cavity 101 reaches the first water level L1, the first water level L1 is higher than the third water level, and at this time, the water level in the washing cavity 201 can be judged to reach the preset water level.
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 preset water level because part of the laundry "absorbs water" slowly. Therefore, after stopping the water injection for a preset time, the water injection into the washing chamber 201 needs to be performed again to ensure that the water level reaches the standard in the subsequent normal washing process.
It should be noted that the values of the first water level L1 and the third water level are not fixed, but may be variable.
In one embodiment, the control method further comprises:
after the water level of the water storage cavity 101 reaches the first water level L1, injecting water into the water storage cavity 101 until the water in the water storage cavity 101 reaches the second water level L2; the second water level L2 is higher than the first water level L1; 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.
In the rotation process of the inner barrel 20, different parts of the inner barrel 20 are contacted with the hot water in the outer barrel 10 in turn, namely, the inner barrel 20 and the hot water have relative motion, 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 one embodiment, referring to fig. 1 and 2, the step of enabling the water in the water storage cavity 101 to reach the second water level L2 specifically includes: the first water path 42 is controlled to supply 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 to reach the first water level L1. After the water level of the water storage chamber 101 reaches the first water level L1, the first water path 42 is closed and the second water path 43 is controlled to fill water into the water storage chamber 101 until the water in the water storage chamber 101 reaches the second water level L2. That is, water is first injected into the washing chamber 201 through the first water path 42 until the water in the washing chamber 201 overflows to the water storage chamber 101 from the overflow port and reaches the first water level L1 lower than the second water level L2, and then the water injection into the washing chamber 201 is stopped, and then the second water path 43 is controlled to directly inject water into the washing chamber 201 until the water level in the water storage chamber 101 reaches the second water level L2, so that excessive water is prevented from being adsorbed on the inner wall of the washing chamber 201, and when the rotation speed of the inner tub 20 is reduced or the rotation is stopped while water is saved, a large amount of water is prevented from flowing into the water storage chamber 101 from the overflow port, and the water level in the water storage chamber 101 is rapidly increased.
It is understood that, if necessary, the first water path 42 may be controlled to supply 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 L1. After the water level in the water storage chamber 101 reaches the first water level L1, the first water path 42 is controlled to continue to supply water into the washing chamber 201, that is, the water in the washing chamber 201 continues to overflow from the overflow port to the water storage chamber 101, and the second water path 43 is controlled to supply water into the water storage chamber 101 until the water in the water storage chamber 101 reaches the second water level L2.
In an embodiment, before the water in the water storage chamber 101 reaches the second water level L2, the control method includes: it is determined that heating is required.
