- the outer tub is equipped with a water level detection device for detecting the water level in the outer tub.
- the washing machine detects the water level through the water level detection device.
- the height of the water outlet 11 is controlled by the control valve 12, and the closing of the water outlet 11 is controlled by the control valve 12 to prevent the washing water from draining from the inner tub 1 to the outer tub 2.
- the bottom surface of the outer tub 2 is connected with a drain pipe 3 to discharge water.
- a drain pipe 3 to discharge water.
- the inner pipe diameter of the drain pipe 3 should be larger than the diameter of the water outlet hole 11.
- the washing machine opens the water outlet hole 11 through the control valve 12, The washing water in the inner tub 1 flows into the outer tub 2 through the water outlet 11 and is discharged along the drain pipe 3.
- the drain pipe 3 is hung up or the drain pipe 3 is blocked, the water cannot flow smoothly from the drain pipe 3.
- the water in the outer tub 2 will accumulate more and more, and because the height of the outer tub 2 is much lower than the height of the inner tub 1, the water in the outer tub 2 will quickly overflow the outer tub 2, causing the washing machine to overflow and the inside of the washing machine Soaked in water, because there are a lot of debris in the washing water, if the user does not clean it in time, it is easy to cause corrosion to the internal structure and shell of the washing machine. At the same time, the washing water flowing out of the washing machine will also pollute the surrounding environment. The user cleans it up.
- the washing machine can monitor the water level in the outer tub 2 in real time, and open or close the water outlet 11 in a timely manner to prevent the washing water from draining from the inner tub 1 to the outer tub 2. In the middle, cut off the source of water flow in the outer barrel 2 to avoid overflow.

- the height of the outer barrel 2 should not be too high, to avoid that when the drain pipe 3 is blocked, the water inside the outer barrel 2 is too high, soaking the outer wall of the inner barrel 1, while the outer wall of the inner barrel 1 is not easy to clean, and it is easy to breed after a long time. A lot of bacteria.
- a first water level 21 is set at a height h1 from the bottom surface of the outer tub 2.
- the function of the outer tub 2 is to prevent the drain pipe 3 from being directly connected to the water outlet 11 and rotating the inner tub 1 During the process, the drain pipe 3 rotates with the inner tub 1 and shakes accordingly, connecting the drain pipe 3 to the fixed outer tub 2. Since the outer tub 2 is fixed, the drain pipe 3 is fixed during the washing process of the washing machine. 3 will not rotate.
- the bottom of the inner tub 1 extends into the opening of the outer tub 2, the water flowing out of the outlet hole 11 falls into the outer tub 2, and the splashed water is absorbed by the outer tub 2.
- the side wall of the washing machine is intercepted and will not splash out of the outer tub 2 due to the height difference between the inner tub 1 and the outer tub 2, which further ensures that the inside of the washing machine will not be corroded by the washing water.
- the height h1 of the first water level 21 is less than the distance between the bottom of the inner tub 1 and the bottom surface of the outer tub 2. Since the bottom of the inner tub 1 extends into the opening of the outer tub 2, if h1 is greater than The distance between the ground of the inner tub 1 and the bottom surface of the outer tub 2. During the drainage process, if the drain pipe 3 is hung or blocked, causing poor drainage, the washing water level in the outer tub 2 will become higher and higher.

- the water in the inner tub 1 flows into the outer tub 2 through the water outlet 11 and is discharged through the drain pipe 3;
- Step S2 the water level detection device is activated and detects the water level in the outer barrel 2;
- Step S3 If the water level in the outer tub 2 reaches the highest height of the outer tub 2, the water level signal is fed back to the washing machine, and the washing machine controls the water outlet 11 to close.
- the water level in the outer tub 2 exceeds the highest height of the outer tub 2, it means that the drain pipe 3 is hung or blocked, causing the washing water in the outer tub 2 to be unable to drain smoothly.
- the water level exceeds the maximum height of the outer tub 2, that is, it will overflow the outer tub 2.
- the water level is fed back to the washing machine, and the washing machine controls the water outlet 11 to close immediately to avoid greater losses.
- the water level in the outer barrel 2 is detected by a water level detection device, and the outlet hole 11 is closed when the water in the outer barrel 2 overflows.

- the heights of the first water level 21 and the second water level 22 can be adjusted according to different types of washing machines.
- the first water level 21 and the second water level 22 are set at one-third and two-thirds of the outer tub 2, respectively.
- this height setting solution is that when the water level reaches the first water level 21, part of the water will be discharged into the outer bucket 2 when the water outlet 11 is closed, but the water level in the outer bucket 2 will not reach the second water level 22.
- the setting of the second water level 22 is also to avoid the failure of the water level detection device and the failure to detect that the water level has reached the first water level 21 in time
- the washing machine controls the water outlet 11 to close.
- the water level in the outer tub 2 rises.

- the water level detection device feeds back the water level signal to the washing machine.
- the washing machine controls the water outlet 11 to open, and the water outlet 11 is in the closed state at this time.
- the washing water in the inner tub 1 will not be discharged into the outer tub 2, and the water level in the outer tub 2 reaches the emptying level within t2, indicating that the blockage in the drain pipe 3 is not very serious, and it also has a certain drainage function. Therefore, after the washing machine controls the water outlet 11 to open and close multiple times, the water in the outer tub 2 can still be drained without overflowing, and it will not take too long.
- an alarm for the blockage of the drain pipe 3 is issued and displayed on the display panel of the washing machine to remind the user that the drain pipe 3 is slightly blocked.
- the blockage does not affect this wash, it is After being placed in the environment for a period of time, it is easy to breed more bacteria or produce peculiar smell. If it is blocked and enters the sewer pipe, it is more likely to cause the sewer pipe to be blocked. Therefore, the user needs to be reminded in time for cleaning.

Abstract
A control method for a washing machine. When a water outlet hole (11) arranged at an inner drum (1) is opened and a drainage process is executed, waste wash water contained in the inner drum (1) flows to an outer drum (2) via the water outlet hole (11), and then the waste wash water is drained via a drainage pipe (3) in communication with the outer drum (2). Detection is performed on a water level in the outer drum (2). When the water level in the outer drum (2) exceeds a preset water level, the water outlet hole (11) is closed. The above arrangement ensures that a washing machine can operate normally while preventing occurrence of an internal overflow in the washing machine, thereby protecting an internal structure of the washing machine, and extending service life of the washing machine. Moreover, multiple types of alarms are used to inform a user of a blockage and a degree of the blockage in a washing process performed by a washing machine, such that the user can make a timely check and resolve the blockage. The washing machine has a simple structure and enhanced operability.

如图1所示,本实施例中介绍了一种洗衣机,其包括内桶1,在洗衣机执行洗涤程序时形成盛水容器的内桶1;内桶1外设有外桶2,内桶1设有供洗涤水流向外桶2的出水孔11,出水孔11处安装有控制其开闭的控制阀12,外桶上设置有用以检测外桶内水位高度的水位检测装置,洗衣机通过水位检测装置检测的水位高度,并通过控制阀12控制出水孔11的启闭,通过控制阀12控制出水孔11的关闭,阻止洗涤水从内桶1排至外桶2中,外桶2底面连接有排水管3,出水孔11打开时内桶1、外桶2和排水管3连通,其中排水管3的内管直径应大于出水孔11的直径,当洗衣机进行排水的时候,洗衣机通过控制阀12将出水孔11打开,内桶1中的洗涤水通过出水孔11流至外桶2中,并沿排水管3排出,当排水管3被挂起或是排水管3堵塞等情况的时候,水流无法顺利的从排水管3中排出,外桶2中的水会越积越多,且由于外桶2高度远低于内桶1高度,外桶2中的水很快便会溢出外桶2,造成洗衣机的溢水,洗衣机内部被水浸泡,由于洗涤水中夹杂着大量的杂物,如用户没有及时清理干净,很容易对洗衣机内部结构以及壳体造成腐蚀,同时洗涤水流出洗衣机外,还会对周围的环境造成污染,需要用户去清理干净,通过在外桶2上设置的水位检测装置,洗衣机能够实时的监控外桶2内的水位高度,同时适时的开启或关闭出水孔11,阻止洗涤水从内桶1排至外桶2中,断绝外桶2中水流来源,避免发生溢水的情况。As shown in Figure 1, this embodiment introduces a washing machine, which includes an inner tub 1, which forms an inner tub 1 for a water container when the washing machine executes a washing procedure; an outer tub 2 is provided outside the inner tub 1, and an inner tub 1 is provided for washing Water flows to the water outlet 11 of the outer tub 2. A control valve 12 is installed at the outlet 11 to control its opening and closing. The outer tub is equipped with a water level detection device for detecting the water level in the outer tub. The washing machine detects the water level through the water level detection device. The height of the water outlet 11 is controlled by the control valve 12, and the closing of the water outlet 11 is controlled by the control valve 12 to prevent the washing water from draining from the inner tub 1 to the outer tub 2. The bottom surface of the outer tub 2 is connected with a drain pipe 3 to discharge water. When the hole 11 is opened, the inner tub 1, the outer tub 2 and the drain pipe 3 are connected. The inner pipe diameter of the drain pipe 3 should be larger than the diameter of the water outlet hole 11. When the washing machine is draining water, the washing machine opens the water outlet hole 11 through the control valve 12, The washing water in the inner tub 1 flows into the outer tub 2 through the water outlet 11 and is discharged along the drain pipe 3. When the drain pipe 3 is hung up or the drain pipe 3 is blocked, the water cannot flow smoothly from the drain pipe 3. The water in the outer tub 2 will accumulate more and more, and because the height of the outer tub 2 is much lower than the height of the inner tub 1, the water in the outer tub 2 will quickly overflow the outer tub 2, causing the washing machine to overflow and the inside of the washing machine Soaked in water, because there are a lot of debris in the washing water, if the user does not clean it in time, it is easy to cause corrosion to the internal structure and shell of the washing machine. At the same time, the washing water flowing out of the washing machine will also pollute the surrounding environment. The user cleans it up. Through the water level detection device set on the outer tub 2, the washing machine can monitor the water level in the outer tub 2 in real time, and open or close the water outlet 11 in a timely manner to prevent the washing water from draining from the inner tub 1 to the outer tub 2. In the middle, cut off the source of water flow in the outer barrel 2 to avoid overflow.
如图1所示,本实施例中,外桶2顶部高于内桶1底部、外桶2底部低于内桶1底部,外桶2顶部低于内桶1高度的一半,外桶2顶部高于内桶1底部、外桶2底部低于内桶1底部,避免了出水孔11内排出的水落入外桶2时造成飞溅,溅至外桶2外,时间长了也会对洗衣机内部的结构造成损坏,同时外桶2的高度也不宜过高,避免在排水管3堵塞时,外桶2内部的积水过高,浸泡内桶1的外壁,而内桶1的外壁不容易清理,时间长了容易滋生大量的细菌。As shown in Figure 1, in this embodiment, the top of the outer barrel 2 is higher than the bottom of the inner barrel 1, the bottom of the outer barrel 2 is lower than the bottom of the inner barrel 1, the top of the outer barrel 2 is lower than half of the height of the inner barrel 1, and the top of the outer barrel 2 is higher than the inner barrel. 1 The bottom and the bottom of the outer tub 2 are lower than the bottom of the inner tub 1, avoiding splashing when the water discharged from the water outlet 11 falls into the outer tub 2, and splashing out of the outer tub 2, which will damage the internal structure of the washing machine after a long time. At the same time, the height of the outer barrel 2 should not be too high, to avoid that when the drain pipe 3 is blocked, the water inside the outer barrel 2 is too high, soaking the outer wall of the inner barrel 1, while the outer wall of the inner barrel 1 is not easy to clean, and it is easy to breed after a long time. A lot of bacteria.
如图1所示,本实施例中,在距离外桶2底面高度h1处设置有第一水位21,其中外桶2的作用是避免排水管3直接与出水孔11连接,在内桶1转动的过程中,排水管3随着内桶1转动,并随之甩动,将排水管3连接到固定的外桶2上,由于外桶2是固定设置,所以在洗衣机进行洗涤的过程中,排水管3也不会转动,在排水过程中,由于内桶1桶底部分伸入至外桶2的敞口内,自出水孔11中流出的水流落至外桶2中,飞溅其的水被外桶2的侧壁拦截,不会由于内桶1与外桶2的高度差飞溅至外桶2外,进一步保证了洗衣机内不会被洗涤水腐蚀。As shown in Figure 1, in this embodiment, a first water level 21 is set at a height h1 from the bottom surface of the outer tub 2. The function of the outer tub 2 is to prevent the drain pipe 3 from being directly connected to the water outlet 11 and rotating the inner tub 1 During the process, the drain pipe 3 rotates with the inner tub 1 and shakes accordingly, connecting the drain pipe 3 to the fixed outer tub 2. Since the outer tub 2 is fixed, the drain pipe 3 is fixed during the washing process of the washing machine. 3 will not rotate. During the draining process, since the bottom of the inner tub 1 extends into the opening of the outer tub 2, the water flowing out of the outlet hole 11 falls into the outer tub 2, and the splashed water is absorbed by the outer tub 2. The side wall of the washing machine is intercepted and will not splash out of the outer tub 2 due to the height difference between the inner tub 1 and the outer tub 2, which further ensures that the inside of the washing machine will not be corroded by the washing water.
如图1所示,本实施例中,第一水位21的高度h1小于内桶1桶底至外桶2底面之间距离,由于内桶1桶底部分伸入外桶2的敞口内,若h1大于内桶1桶地至外桶2底面之间的距 离,在排水过程中,若排水管3被挂起或发生堵塞,造成排水不畅时,外桶2内洗涤水的水位会越来越高,当洗涤水没过内桶1桶底,并长时间浸泡会对内桶1外壁造成腐蚀,且内桶1外壁极不易清理,用户在使用过程中,能够发现内桶1内壁山的残留污渍,但是无法观察到内桶1外壁上的残留污渍,衣物上的细菌以及其他杂质附着在内桶1外壁上,时间长了极易损伤内桶1外壁,所以将第一水位21的高度h1小于内桶1桶底至外桶2底面之间距离,在外桶2内的水位未达到第一水位21的时候,持续排水,即使排水管3被挂起或发生堵塞,造成排水不畅,水位缓慢上升,当到达第一水位21的时候,洗衣机控制出水孔11关闭,防止外桶2中的洗涤没过内桶1底部,进一步延长了洗衣机的寿命,减少了洗衣机的故障率。As shown in Figure 1, in this embodiment, the height h1 of the first water level 21 is less than the distance between the bottom of the inner tub 1 and the bottom surface of the outer tub 2. Since the bottom of the inner tub 1 extends into the opening of the outer tub 2, if h1 is greater than The distance between the ground of the inner tub 1 and the bottom surface of the outer tub 2. During the drainage process, if the drain pipe 3 is hung or blocked, causing poor drainage, the washing water level in the outer tub 2 will become higher and higher. When the washing water has submerged the bottom of the inner tub 1 and soaked for a long time, it will corrode the outer wall of the inner tub 1, and the outer wall of the inner tub 1 is extremely difficult to clean. The user can find the residual dirt on the inner wall of the inner tub 1 during use, but the inner tub cannot be observed. 1 Residual stains on the outer wall, bacteria and other impurities on the clothes adhere to the outer wall of the inner tub 1, and it is easy to damage the outer wall of the inner tub 1 for a long time, so the height h1 of the first water level 21 is smaller than the bottom of the inner tub 1 to the bottom of the outer tub 2 When the water level in the outer bucket 2 does not reach the first water level 21, continue to drain, even if the drain pipe 3 is hung or blocked, causing poor drainage, the water level rises slowly, and when it reaches the first water level 21 , The washing machine controls the water outlet 11 to close to prevent the washing in the outer tub 2 from surpassing the bottom of the inner tub 1, further extending the life of the washing machine and reducing the failure rate of the washing machine.
本实施例中,介绍了一种洗衣机的控制方法,In this embodiment, a method for controlling a washing machine is introduced.
包括如下步骤Including the following steps
步骤S1:洗衣机开始排水,并开启出水孔,内桶1中的水通过出水孔11流至外桶2内并通过排水管3排出;Step S1: The washing machine starts to drain water and opens the water outlet. The water in the inner tub 1 flows into the outer tub 2 through the water outlet 11 and is discharged through the drain pipe 3;
步骤S2:水位检测装置启动并检测外桶2中的水位高度;Step S2: the water level detection device is activated and detects the water level in the outer barrel 2;
步骤S3:若外桶2内水位高度达到外桶2最高高度,则将水位高度信号反馈至洗衣机,洗衣机控制出水孔11关闭。Step S3: If the water level in the outer tub 2 reaches the highest height of the outer tub 2, the water level signal is fed back to the washing machine, and the washing machine controls the water outlet 11 to close.
其中外桶2内的水位高度如果超过了外桶2的最高高度,则说明排水管3被挂起或者堵塞了造成了外桶2内的洗涤水无法顺利的排出,当外桶2内的洗涤水的水位高度超过了外桶2的最高高度,也就是即将溢出外桶2,此时的水位高度反馈至洗衣机,洗衣机控制出水孔11立即关闭,避免造成更大的损失,这也是一个最简单的技术方案,通过水位检测装置检测外桶2中的水位,当发生外桶2中水溢出时关闭出水孔11,但是也存在一定的技术缺陷,尤其是当出水孔11的出水流速和/或出水流量过大时,即使水位检测装置及时的检测到了外桶2中的水即将溢出外桶2,但是水位高度信号的反馈,以及洗衣机控制出水阀13将出水孔11的关闭都需要一定的操作时间,所以多少都会有水溢出外桶2。If the water level in the outer tub 2 exceeds the highest height of the outer tub 2, it means that the drain pipe 3 is hung or blocked, causing the washing water in the outer tub 2 to be unable to drain smoothly. The water level exceeds the maximum height of the outer tub 2, that is, it will overflow the outer tub 2. At this time, the water level is fed back to the washing machine, and the washing machine controls the water outlet 11 to close immediately to avoid greater losses. This is also the simplest In the technical solution, the water level in the outer barrel 2 is detected by a water level detection device, and the outlet hole 11 is closed when the water in the outer barrel 2 overflows. However, there are also certain technical defects, especially when the water outlet flow rate and/or the outlet hole 11 When the outlet water flow is too large, even if the water level detection device detects that the water in the outer tub 2 is about to overflow the outer tub 2 in time, the feedback of the water level signal and the washing machine controlling the water outlet valve 13 to close the water outlet 11 require certain operations. Time, so some water will overflow the outer bucket 2.
本实施例中,上述步骤S3中,若水位检测装置检测外桶2中水位高度低于第一水位21,则持续排水,在水位未达到第一水位21之前,说明排水管3能够正常排水,排水管3未被堵塞,或即使排水管3发生了堵塞,其堵塞程度也暂时也不会影响到排水,出水孔11排至外桶2中的水大部分还是能够通过排水管3排出的,外桶2内也不会发生积水过多的情况,短时间内不会发生溢水等情况的发生,能够在一段时间内维持外桶2中的水位以较慢的速度增长,所以可以持续的进行排水工作。In this embodiment, in the above step S3, if the water level detecting device detects that the water level in the outer tub 2 is lower than the first water level 21, the water will continue to drain. Before the water level reaches the first water level 21, it is indicated that the drain pipe 3 can drain normally. The drain pipe 3 is not blocked, or even if the drain pipe 3 is blocked, the degree of blockage will not affect the drainage temporarily. Most of the water discharged from the water outlet hole 11 into the outer tub 2 can still be discharged through the drain pipe 3. There will be no excessive accumulation of water in the outer barrel 2, and no overflow in a short period of time. The water level in the outer barrel 2 can be maintained at a slower rate for a period of time, so it can be sustained Perform drainage work.
本实施例中,上述步骤S3中,在外桶2上距离外桶2底面高度h2处设置有第二水位22,且第二水位22距离外桶2底面的高度h2高于第一水位距离外桶底面的高度h1,当水位检测装置检测外桶2中水位高度高于第一水位21且低于第二水位22时,将该水位高度信号反馈至洗衣机,洗衣机控制出水孔11关闭,上述实施例中将触发洗衣机控制出水孔11关闭的水位高度设置为外桶2中水位达到最高高度,但是在实际使用过程中,出水孔11中持续排出洗涤水,此时由于排水管3完全失去排水功能或部分失去排水功能导致的水位上升,即使水位检测装置检测到水位达到外桶2内的最高高度,但是将水位高度信号反馈至控制板、控制板控制将出水孔11关闭信号发出、出水孔11关闭,这一系列的工作无法在检测出水位高度的瞬间完成,所以此时水位还会发生部分的上涨,外桶2中的水则会溢出外桶2,为了避免这一情况的发生,将第一水位21设置为洗衣机控制出水孔11关闭的水位,进一步防止溢水的情况发生。In this embodiment, in the above step S3, a second water level 22 is set on the outer tub 2 at a height h2 from the bottom surface of the outer tub 2, and the height h2 of the second water level 22 from the bottom surface of the outer tub 2 is higher than the first water level from the outer tub 2 The height h1 of the bottom surface. When the water level detecting device detects that the water level in the outer tub 2 is higher than the first water level 21 and lower than the second water level 22, the water level signal is fed back to the washing machine, and the washing machine controls the water outlet 11 to close, as in the above embodiment The water level that triggers the closing of the water outlet 11 of the washing machine is set as the water level in the outer tub 2 reaches the highest height, but in actual use, the water outlet 11 continues to drain the washing water. At this time, the drain pipe 3 completely loses its drainage function or The water level rise caused by partial loss of drainage function, even if the water level detection device detects that the water level reaches the highest height in the outer bucket 2, the water level height signal is fed back to the control board, and the control board controls the water outlet 11 to close the signal and the water outlet 11 to close , This series of work cannot be completed at the moment the water level is detected, so at this time the water level will rise partially, and the water in the outer bucket 2 will overflow the outer bucket 2. In order to avoid this situation, the first A water level 21 is set as the water level at which the washing machine controls the water outlet 11 to close, so as to further prevent the occurrence of water overflow.
其中第一水位21和第二水位22的高度可以根据不同型号的洗衣机进行相应的调整,例如第一水位21和第二水位22分别设置在外桶2的三分之一和三分之二处,而这个高度设置的方案为当水位达到第一水位21时,出水孔11关闭的过程中也会有部分水排至外桶2中,但是外桶2中的水位不会达到第二水位22,进一步保证了在关闭出水孔11的过程中,外桶2中的水不会溢出,且第二水位22的设置也是避免水位检测装置出现故障导致未及时的检测到水位已经达到第一水位21的高度,当水位超过第二水位22时,若此时出水孔11未处于关闭状态,则洗衣机控制出水孔11关闭,同样的,再关闭出水孔11的过程中,外桶2中的水位上涨,同样不会达到外桶2的最高高度,避免了外桶2中的水溢出,进一步保证了外桶2中的水不会溢出外桶2,以上的举例仅为一种实施方式,实际情况需要根据不同机型进行相应的调整。The heights of the first water level 21 and the second water level 22 can be adjusted according to different types of washing machines. For example, the first water level 21 and the second water level 22 are set at one-third and two-thirds of the outer tub 2, respectively. And this height setting solution is that when the water level reaches the first water level 21, part of the water will be discharged into the outer bucket 2 when the water outlet 11 is closed, but the water level in the outer bucket 2 will not reach the second water level 22. It is further ensured that in the process of closing the water outlet 11, the water in the outer tub 2 will not overflow, and the setting of the second water level 22 is also to avoid the failure of the water level detection device and the failure to detect that the water level has reached the first water level 21 in time When the water level exceeds the second water level 22, if the water outlet 11 is not closed at this time, the washing machine controls the water outlet 11 to close. Similarly, when the water outlet 11 is closed again, the water level in the outer tub 2 rises. Similarly, it will not reach the highest height of the outer barrel 2, avoiding the overflow of water in the outer barrel 2, and further ensuring that the water in the outer barrel 2 will not overflow the outer barrel 2. The above example is only an implementation method, and the actual situation requires Make corresponding adjustments according to different models.
本实施例中,出水孔11关闭后,若水位高度持续高于第一水位21的时间大于t1,则发出溢水警报,此时出水孔11已经关闭,内桶1中的洗涤水不会再排入外桶2中,但是水位高度迟迟不下降的原因是由于排水管3被挂起或排水管3彻底堵塞,导致了排水管3中无法排水,外桶2中的洗涤水一直积存在外桶2中,或是排水管3堵塞的情况十分严重,倒是即使外桶2中的洗涤水有很少的一部分被排出,但是排出的水量过少,水位还是在第一水位21之上,水位并没有在t1时间内下降至第一水位21之下,此时向用户发出溢水警报,提醒用户外桶2内水位异常的同时也提醒了用户排水管3被挂起或是被彻底堵塞,失去了排水功能,此时需要用户及时检查排水管3是否被挂起,如果排水管3不是处于挂起的状态,则需要用户检查排水管3的堵塞情况,并及时疏通。In this embodiment, after the water outlet 11 is closed, if the water level continues to be higher than the first water level 21 for a time greater than t1, an overflow alarm is issued. At this time, the water outlet 11 has been closed, and the washing water in the inner tub 1 will no longer be discharged The reason why the water level in the outer tub 2 does not drop slowly is that the drain pipe 3 is hung or the drain pipe 3 is completely blocked, causing the drain pipe 3 to fail to drain, and the washing water in the outer tub 2 has been accumulated in the outer tub 2 Or the drain pipe 3 is blocked very seriously. Even though a small part of the washing water in the outer tub 2 is discharged, but the amount of water discharged is too small, the water level is still above the first water level 21, and the water level is not It drops below the first water level 21 within t1. At this time, an overflow alarm is issued to the user, reminding the user that the water level in the outer bucket 2 is abnormal, and also reminding the user that the drain pipe 3 is hung up or completely blocked, and the drain is lost. In this case, the user needs to check whether the drain pipe 3 is suspended in time. If the drain pipe 3 is not in a suspended state, the user needs to check the blockage of the drain pipe 3 and unblock it in time.
本实施例中,出水孔11关闭后,若平外桶2内的水位在t1时间内下降至第一水位之下,但是在t2时间内仍未达到将外桶2中的水全部排空的排空水位,则发出排水超时警报,此时出水孔11处于关闭状态,内桶1中的洗涤水不会再排入外桶2中,水位的下降,说明排水管3并未彻底被堵塞,其还具有一定的排水功能,但是由于部分被堵塞,所以排水能力下降,水流量减小,无法在短时间内将外桶2内的洗涤水排空,所以,在t1时间内水位下降至第一水位21之下,但是未达到排空水位,此时发出排水超时警报,告知用户排水管3正常与下水管道连接,但是其部分堵塞,需要清理后继续洗衣。In this embodiment, after the water outlet 11 is closed, if the water level in the flat outer tub 2 drops below the first water level within t1, but it has not reached the level of emptying all the water in the outer tub 2 within t2. When the water level is emptied, a drain overtime alarm is issued. At this time, the water outlet 11 is closed, and the washing water in the inner tub 1 will not be discharged into the outer tub 2. The drop of the water level indicates that the drain pipe 3 is not completely blocked. It also has a certain drainage function, but due to partial blockage, the drainage capacity is reduced, and the water flow is reduced. It is impossible to empty the washing water in the outer tub 2 in a short time. Therefore, the water level drops to the first within t1.
