Through the second air duct 500, in the washing process of the washing liner 100, air in the washing liner 100 can be discharged through the second air duct 500, or communication with the outside is realized. Can effectively bypass fan 200 and negative pressure connecting piece 300 through second wind channel 500, guarantee the stability of circulation of air in the washing courage 100 in the washing process.

In other embodiments, the first air duct 400 may be separated from the second air duct 500, and one end of the second air duct 500 is separately communicated with the washing tub 100. The other end of the second air duct 500 is provided separately from the first air duct 400, as long as the air in the washing tub 100 can stably circulate through the second air duct 500 in the washing process.

Referring to fig. 5 and 6, in another embodiment, one end of the second air duct 500 is connected to the air inlet pipe 410, and the other end is separated from the air outlet pipe 420. Because the exhaust pipe 420 is separated from the other end of the second air duct 500, the residual water discharged from the exhaust pipe 420 can be further prevented from entering the second air duct 500.

Specifically, the drainage assembly further includes a connection pipe 430, the second air duct 500 is located above the exhaust duct 420, one end of the connection pipe 430 is connected to the exhaust duct 420, and the other end of the connection pipe 430 is connected to the other end of the second air duct 500. Because the exhaust pipe 420 is located above the second air duct 500, and then in the process of discharging the residual water, the fan 200 blows and drives the residual water, so that the residual water can flow into the exhaust pipe 420 by self weight and be discharged. The air blown by the blower 200 can enter the second air duct 500 through the connecting pipe 430, and the air is exhausted through the second air duct 500. The effect of a certain separation of air discharge and water discharge is achieved by the connection pipe 430, thereby facilitating the improvement of the water discharge effect.

In this embodiment. The connection pipe 430 is inclined from the exhaust pipe 420 to the second air duct 500 in a direction away from the blower 200. Because the air blown by the fan 200 can be blown into the second air duct 500 through the connecting pipe 430, and further possibly carrying part of the residual water into the connecting pipe 430, the connecting pipe 430 is arranged obliquely, on one hand, the air can flow along the flowing time of the long wind in the connecting pipe 430, and further, the residual water can be conveniently contacted with the pipe wall of the connecting pipe 430 and further condensed; on the other hand, the condensed residual water can flow back to the exhaust pipe 420 along the pipe wall of the connecting pipe 430 and is discharged from the exhaust pipe 420.

Optionally, one end of the connection pipe 430 is in communication with the second tuyere 312. By communicating the connection pipe 430 with the second air opening 312, the blower 200 can blow air into the connection pipe 430 effectively, and the possibility of blowing air into the exhaust duct 420 is reduced.

Referring to fig. 3 and 4, in an embodiment, the drainage assembly further includes a blocking member 600, the blocking member 600 is disposed in the exhaust duct 420 and located at a communication position between the second air duct 500 and the exhaust duct 420, and the blocking member 600 is movably connected to the exhaust duct 420 to block the exhaust duct 420 or block the second air duct 500. As shown in fig. 3, when the washing tub 100 washes the articles, the blocking member 600 blocks the exhaust duct 420, so that the air in the washing tub 100 can effectively circulate through the second air duct 500. As shown in fig. 4, when it is necessary to dry or discharge residual water, the blocking member 600 blocks the second air duct 500, the blower 200 is started, and the wet air in the washing tub 100 is pumped out through the air inlet pipe 410 and enters the exhaust pipe 420 through the negative pressure passage, at this time, since the blocking member 600 blocks the second air duct 500, the wet air is prevented from flowing back into the second air duct 500, and the wet air is effectively discharged. Meanwhile, by forming a negative pressure at the first inlet port 330, the remaining water is introduced into the negative pressure passage and stably discharged by the exhaust duct 420.

Specifically, the other end of the second air duct 500 is connected to the upper side of the exhaust duct 420, and one side of the blocking member 600 is rotatably disposed at the communication position between the second air duct 500 and the exhaust duct 420. As shown in fig. 3, when the blower 200 is not started, the blocking member 600 rotates at the communication position between the second air duct 500 and the exhaust duct 420 due to the self-weight of the blocking member 600, and the exhaust duct 420 is located below, so that the exhaust duct 420 can be covered by the blocking member 600. As shown in fig. 4, after the blower 200 is started, since the blower 200 blows air to the exhaust pipe 420, the blocking member 600 can be blown up from the exhaust pipe 420 to blow to the second air duct 500, so as to block the second air duct 500. The blocking piece 600 can automatically control the blocking of the exhaust pipe 420 and the second air duct 500, so that the manual operation is avoided, and the labor cost is increased.

In this embodiment, the blocking member 600 is a plate-shaped structure, one side of the plate-shaped structure is rotatably disposed at a communication position between the second air duct 500 and the exhaust duct 420, and one side of the plate-shaped structure is disposed near the air inlet duct 410. By setting the blocking member 600 to have a plate-like structure, the blocking effect on the exhaust duct 420 and the second air duct 500 can be more conveniently achieved.

Referring to fig. 5 and 6, in another embodiment, the blocking member 600 is disposed in the second air duct 500 and located at a communication position between the second air duct 500 and the connecting pipe 430, and the blocking member 600 is movably connected to the second air duct 500 to block the connecting pipe 430 or the second air duct 500. As shown in fig. 5, when the washing tub 100 washes the articles, the blocking member 600 blocks the connecting pipe 430, so that the air in the washing tub 100 can effectively circulate through the second air duct 500. As shown in fig. 6, when it is necessary to dry or discharge residual water, the blocking member 600 blocks the second air duct 500, the blower 200 is started, and the wet air in the washing tub 100 is pumped out through the air inlet pipe 410, enters through the negative pressure channel, and is discharged out through the second air duct exhaust pipe 420 through the connection pipe 430, at this time, since the blocking member 600 blocks the second air duct 500, the wet air is prevented from flowing back into the washing tub 100 through the second air duct 500.

Referring to fig. 3 and 7, in an embodiment, the drainage assembly further includes a separating member 700, the separating member 700 forms a separating cavity 710, an exhaust port 720 communicated with the separating cavity 710 is formed on a top wall of the separating member 700, a drain 730 and a second inlet 740 communicated with the separating cavity 710 are further formed on the separating member 700, the drain 730 is disposed on a bottom wall of the separating cavity 710 or is disposed at a position close to the bottom wall of the separating cavity 710, and the second inlet 740 is communicated with the second inlet 312. Since the second inlet 740 is communicated with the second air inlet 312, the air or water blown out from the second air inlet 312 can effectively enter the separation chamber 710, and since the air is located above the separation chamber 710, the air or water can be discharged from the air outlet 720 on the top wall of the separation chamber 710. The water is discharged from the drain 730 on or near the bottom wall of the separation chamber 710 due to the gravity of the water, which is located below the separation chamber 710. The water and gas separation is effectively achieved by the separator 700. In other embodiments, the separator 700 may also be omitted.

Specifically, an end of the exhaust duct 420 remote from the intake duct 410 communicates with the second inlet port 740. In the above embodiment, the other end of the second air duct 500 is connected to the exhaust pipe 420, and the exhaust pipe 420 is further communicated with the second inlet 740, so that the first air duct 400 and the second air duct 500 are both separated from water and then discharged respectively through the same separating member 700, and the separating member 700 is not arranged on the first air duct 400 and the second air duct 500, which increases the structural cost and increases the structural size of the washing device.

Optionally, the bottom wall of the separation chamber 710 is inclined downwards from the second inlet 740 to the drain 730. When the water and wind exhausted by the exhaust duct 420 enter the separation chamber 710, the water falls on the bottom wall of the separation chamber 710 due to the gravity, and the bottom wall of the separation chamber 710 is inclined downward from the second inlet 740 to the drain 730, so that the water in the separation chamber 710 can effectively flow to the drain 730 and be discharged, and the drainage efficiency is improved.

In this embodiment, the bottom wall of the separation chamber 710 may be a flat surface. In other embodiments, the bottom wall of the separation chamber 710 may also be a curved surface, so long as the bottom wall of the separation chamber 710 tends to be disposed downward from the second inlet 740 to the drain 730.

In one embodiment, an air baffle 750 is disposed in the separation chamber 710, a distance is provided between the air baffle 750 and the bottom wall of the separation chamber 710, the air outlet 720 and the second inlet 740 are located on the same side of the air baffle 750, and the water outlet 730 is located on the other side of the air baffle 750 opposite to each other. Can effectively keep off the windage that exhaust pipe 420 blew out in the one side of air baffle 750 towards second inlet port 740 through setting up air baffle 750 for wind is discharged by gas vent 720 steadily, and rivers can flow out by outlet 730 through the interval between the diapire of air baffle 750 and separation chamber 710, further improve the stability of aqueous vapor separation.

Referring to fig. 2, 3 and 8, in an embodiment, the method for draining water of a washing apparatus in any of the above embodiments includes the following steps:

step S110: detecting residual water in the washing tank 100; specifically, a detection sensor 130 is disposed on the bottom wall of the washing tub 100, and the detection of the residual water in the washing tub 100 is realized by the detection sensor 130, so that it can be determined whether the subsequent steps are required to be performed.

Step S120: triggering a residual water draining signal; specifically, when the detection sensor 130 detects the residual water, the residual water discharge signal is triggered. In the present embodiment, in order to ensure the detection accuracy, the detection sensor 130 is disposed on the bottom wall of the washing tub 100 or at a position close to the bottom wall, so that the residual water can be more accurately detected.

And starting the fan 200 according to the residual water discharge signal.

In the drainage method of the washing equipment, the residual water in the washing container 100 is detected, when the residual water in the washing container 100 is detected, the residual water drainage signal is triggered, and the fan 200 is started according to the residual water drainage signal, so that the fan 200 blows air to the negative pressure channel through the first air opening 322 of the shrinkage tube 320 and blows out the air from the second air opening 312 of the diffusion tube 310. Because the size of the cross section of the contraction tube 320 tends to decrease towards the direction of the diffusion tube 310, the size of the cross section of the diffusion tube 310 tends to increase towards the direction away from the contraction tube 320, and then the wind entering the negative pressure channel passes through the contraction tube 320 to enable the pressure of the wind to gradually increase, and after passing through the communication part of the contraction tube 320 and the diffusion tube 310, the pressure of the wind is suddenly reduced, so that negative pressure can be formed at the first inlet port 330 at the communication part of the contraction tube 320 and the diffusion tube 310, and residual water in the washing container 100 is sucked into the first water inlet port through the residual water discharge port 120 and enters the negative pressure channel under the action of the negative pressure. The remaining water is further discharged from the second tuyere 312 of the diffusion tube 310 by the blower fan 200. Can effectively avoid the residual water to remain in washing courage 100 through above-mentioned drainage assembly, and then can effectively avoid the bacterial growing that the residual water caused, guarantee next washing in-process, the article of being washed is not contaminated.

In one embodiment, the step of detecting the water level in the washing tub 100 further includes:

step S130: if the washing container 100 finishes washing, a drying signal is triggered; specifically, in the using process, the articles are washed by the washing container 100, and then after the washing container 100 finishes washing, a drying signal is triggered, so that the inside of the washing container 100 enters a drying state, and the washed articles are dried.

The blower 200 is started according to the drying signal. Specifically, after starting fan 200, on the one hand can be through taking away the humid air in the washing courage 100, realize the drying to the interior article of washing courage 100, and on the other hand passes through negative pressure connecting piece 300, can realize the discharge to the interior residual water of washing courage 100, realizes the purpose of killing two birds with one stone, practices thrift fan 200 cost, practices thrift the electric energy, improves user's use and experiences.

In another embodiment, the step "triggering a drying signal if the washing bladder 100 finishes washing; starting the fan 200 "according to the drying signal may also be omitted, if the washing tub 100 finishes washing, this directly detects the residual water in the washing tub 100 and performs the subsequent steps.

In an embodiment, the step of starting the blower 200 according to the drying signal further includes: and detecting the residual water in the washing container 100 if the washing container 100 is dried. That is, after the drying of the washing tub 100 is completed, the step S110 is performed. Because the fan 200 keeps the starting state in the drying process of the washing container 100, the residual water in the washing container 100 can be discharged in the drying process. And then after the drying is finished, whether residual water exists in the washing container 100 needs to be judged, and if the residual water is detected, the fan 200 is ensured to be continuously started. When the residual water is not detected, the blower 200 may be controlled to stop, completing the steps of discharging the residual water and drying.
