When the washing machine needs to drain water, water is injected into the water box, so that the water level in the water box is higher than the siphon opening cover, and a siphon effect is formed among the drain pipe, the water box and the water inlet pipe so as to drain water. However, the above structure has the following problems:

1. when the washing machine drains water, even if the washing machine adopts low-water-level washing, water still needs to be filled into the water box, and the siphon effect can be triggered after the water level is higher than the siphon opening cover, so that a large amount of tap water is wasted, and the water-saving effect of the low-water-level washing of the washing machine is lost;

2. after the main washing and rinsing are finished, water drainage is needed firstly, then dehydration is needed, water drainage is still needed in the dehydration process, and otherwise, the water level can not reach part of clothes again. However, in the above structure, after the first drainage is finished, the siphon effect is already interrupted, water generated in the dewatering process cannot be continuously drained, if the second drainage needs to be performed, a large amount of water is injected into the water box again to trigger the siphon effect, and the injected water contacts with clothes in the outer barrel through the water inlet pipe, so that the previous dewatering work is wasted;

3. after the siphon effect is interrupted, the drain pipe is communicated with a sewer, and dirty air can enter the washing machine through the drain pipe and then enter a room.

Therefore, there is a high necessity for a laundry treating apparatus to solve the above problems.

The present embodiment provides a laundry treating apparatus, as shown in fig. 1, which includes a cabinet 1, an outer tub 2 provided within the cabinet 1, and a drainage mechanism. The outer cylinder 2 is used for containing washing liquid, and after washing is completed and in the dehydration process, the washing liquid in the outer cylinder 2 is discharged through the drainage mechanism.

Wherein, the clothes treatment equipment can be a drum washing machine, a drum drying machine or a washing and drying integrated machine.

In the existing clothes treatment equipment, water is discharged mainly through a water discharge pump or a water discharge valve, so that the water discharge energy consumption is increased; some clothes treatment equipment drains water by using a siphon principle, but water resource waste is serious, and dirty air easily enters a room through a washing machine.

To solve the above problem, the drain mechanism includes a communication container 31, a drain pipe 33, a refill unit 38, and an on-off valve 34 as shown in fig. 1. The communication container 31 is disposed beside the outer tub 2, and the communication container 31 communicates with the bottom of the outer tub 2, so that water in the outer tub 2 can enter the communication container 31, and the liquid level of the communication container 31 is the same as that of the outer tub 2. One end of the drain pipe 33 is positioned in the communicating container 31, and the other end of the drain pipe 33 is bent downward after extending from the upper end of the communicating container 31, and the other end of the drain pipe 33 is used for communicating with the outside of the clothes treating apparatus. The water replenishing assembly 38 is communicated with the drain pipe 33, the joint of the water replenishing assembly 38 and the drain pipe 33 is lower than the highest point of the drain pipe 33 and is positioned on one side of the highest point of the drain pipe 33, which is far away from the box body 1, and the water replenishing assembly 38 is used for replenishing water into the drain pipe 33; an on-off valve 34 is provided at the bottom end of the drain pipe 33, the on-off valve 34 being configured to open when the liquid level in the drain pipe 33 reaches a preset level. It will be appreciated that when the liquid level in the drain pipe 33 does not reach the preset level, the on-off valve 34 is closed, so that the bottom end of the drain pipe 33 is closed.

When water is present in the outer tube 2, the outer tube 2 is communicated with the communication container 31, so that the liquid level in the communication container 31 is the same as the liquid level in the outer tube 2, and one end of the drain pipe 33 extending into the communication container 31 is submerged into the water. When the water needs to be drained, the water pipe 33 is filled with water, and as the amount of water increases, the liquid level in the water pipe 33 reaches a preset liquid level, and the drain valve is opened, so that the water in the water pipe 33 is drained to the outside. This will cause the air pressure in the drain pipe 33 to become small, and since the air pressure in the outer tub 2 is atmospheric pressure, the atmospheric pressure will squeeze the water in the outer tub 2, so that the water enters the drain pipe 33 through the communicating container 31, thereby triggering the siphon effect and realizing the drainage of the outer tub 2.

In the embodiment, the water is drained by utilizing the siphon principle, energy consumption is not required for draining, and the operation cost of the clothes treatment equipment can be reduced. Through setting up ooff valve 34 to moisturizing in to drain pipe 33, can be less because of the diameter of drain pipe 33, the water yield that needs the replenishment when reducing and triggering siphon effect, and ooff valve 34 can be when water level is less than preset liquid level H in drainage later stage drain pipe 33 self-closing, makes to leave certain water in the drain pipe 33, needs the water yield of replenishment when reducing the drainage once more, thereby avoids water waste.

In addition, the switch valve 34 closes the drain pipe 33, so that the drain pipe 33 can be separated from a sewer when drainage is not needed, dirty air is prevented from entering a room through the drain pipe 33 and the outer barrel 2, and the use experience of a user is improved.

Specifically, the switching valve 34 includes a valve body 341, a shutter 342, and an elastic member. The bottom end of the drain pipe 33 extends into the valve body 341, a water outlet is arranged at the bottom of the valve body 341, the shutter 342 is rotatably arranged in the valve body 341, the elastic member is connected with the shutter 342, and the elastic member is configured to drive the shutter 342 to shield the bottom port of the drain pipe 33. When the liquid level in the drain pipe 33 is lower than the preset liquid level H, the driving force of the elastic member to the shutter 342 is greater than the water pressure applied to the shutter 342, so that the shutter 342 can block the bottom port of the drain pipe 33. When the water replenishing assembly 38 replenishes water into the drain pipe 33, the liquid level in the drain pipe 33 gradually rises, the water pressure applied to the shutter 342 gradually increases, and the shutter 342 overcomes the elastic force of the elastic member under the action of the water pressure to open the bottom port of the drain pipe 33, so that the liquid in the drain pipe 33 is discharged.

Alternatively, the elastic member may be a torsion spring or a compression spring.

In order to ensure the sealing effect between the door 342 and the bottom end surface of the drain pipe 33, an elastic sealing layer is disposed on the door 342, and the elastic sealing layer can abut against the bottom end surface of the drain pipe 33 to prevent water in the drain pipe 33 from leaking out through a gap between the door 342 and the drain pipe 33.

As the water level in the outer tub 2 decreases, the water level in the communication container 31 also decreases. In order to ensure that the water in the communicating vessel 31 can be drained, the end of the drain pipe 33 needs to be close to the bottom of the communicating vessel 31, which results in a great reduction in the drainage speed, and also inevitably gets clogged with lint in the washing water, making the drainage more difficult, and even having to be manually handled. If the drain pipe 33 is provided at a high position in the communicating vessel 31, although the drainage speed is increased, the drain pipe is not clogged with the lint in the washing water, but the siphon break is easily generated when the water level in the communicating vessel 31 is low, and the water in the communicating vessel 31 cannot be drained completely, and the water generated in the dehydration stage cannot be continuously drained.

In order to solve the above problem, the drain mechanism further includes a float 32, the float 32 is disposed in the communicating container 31 and can float up and down according to the liquid level change in the communicating container 31, and one end of the drain pipe 33 extending into the communicating container 31 is connected to the float 32. The end of the drain pipe 33 extending into the communicating container 31 can move along with the liquid level change in the communicating container 31 by arranging the floater 32, so that the drainage speed is higher when the water level in the communicating container 31 is higher, and the drainage speed is improved; when the water level is low, the water discharging speed is low, so that the washing water can be sucked dry, and the siphon interruption before the dehydration is started can be avoided.

In addition, the drain pipe 33 floats along with the floater 32, so that the blockage of the thread scraps can be avoided, namely, a thread scrap filter is not needed, and the thread scraps are not needed to be cleaned manually. When the water introduced into the communicating vessel 31 contains lint, part of the lint enters the drain pipe 33 and is discharged with the water, and part of the lint is deposited on the bottom of the communicating vessel 31 as the water level in the communicating vessel 31 is lowered. When the water is drained again, the water level in the communicating container 31 rises, the drain pipe 33 rises along with the floater 32, the accumulated thread scraps are prevented from blocking the pipe orifice of the drain pipe 33, the rising water level can disperse the accumulated thread scraps, and the thread scraps accumulated at the bottom of the communicating container 31 can be drained along with the drainage.

In this embodiment, the float 32 and the communication container 31 are provided with a guide structure so that the float 32 can move up and down with the liquid level but does not rotate relative to the communication container 31 to avoid the flexible tube 332 from being entangled and clogged.

Specifically, the cross-sectional shape of the cavity of the communication container 31 and the cross-sectional shape of the float 32 are non-return patterns to restrict the rotation of the float 32. Alternatively, the cross-sectional shape of the cavity and float 32 may be polygonal, elliptical, or irregular. Illustratively, the cross-sectional shape of both the cavity and the float 32 is rectangular.

In order to ensure that water in the outer barrel 2 can be completely discharged, the outer barrel 2 is connected with the communicating container 31 through the connecting pipe 36, one end of the connecting pipe 36 is connected with the bottom of the outer barrel 2, the other end of the connecting pipe is connected with the communicating container 31, and the connecting pipe 36 is obliquely arranged, so that the height of one end, connected with the outer barrel 2, of the connecting pipe 36 is higher than that of one end, connected with the communicating container 31, of the connecting pipe 36, water in the outer barrel 2 can completely enter the communicating container 31 under the action of gravity, and the water in the outer barrel 2 can be completely discharged.

Further, the bottom of the outer cylinder 2 is provided with a soft joint 21, the soft joint 21 is made of a flexible material, the soft joint 21 is connected with the connecting pipe 36, the soft joint 21 can be conveniently installed on the connecting pipe 36, vibration generated in the washing process is prevented from being directly transmitted to the connecting pipe 36, and accidental damage is avoided.

In this embodiment, the drain pipe 33 includes a siphon head 331, a hose 332, an elbow 333, and a straight pipe 334. The siphon head 331, the hose 332, the elbow 333, and the straight pipe 334 are connected in sequence. The siphon head 331 is provided at the bottom of the float 32 so as to always protrude below the liquid level to avoid interruption of the siphon. The bottom end of the hose 332 is connected to the siphon head 331 so as to be deformed as the float 32 floats, thereby preventing interference with the float 32. The elbow 333 is U-shaped and connects the hose 332 to the straight tube 334 to form the highest point of the drain 33 so that a siphoning effect occurs. Since the inside of the drain pipe 33 is under negative pressure during siphoning, all parts of the drain pipe 33 are pipes which can withstand negative pressure. Illustratively, the flexible tube 332 is preferably a lightweight flexible corrugated tube, and the other tube sections may be rigid tubes.

Optionally, the top of the container 31 is open to provide sufficient space for the hose 332 to deform, thereby facilitating the hose 332 to float with the float 32. Further, the float 32 can function as a top cover, and can prevent water inside the communicating container 31 from splashing.

Optionally, the float 32 is a hollow structure, and a central hole is formed in the float 32, a bottom end of the central hole is connected to the siphon head 331, and a top end of the central hole is connected to the hose 332. Through setting up the centre bore, can make things convenient for the connection of hose 332 and siphon tube head 331 on the one hand, on the other hand can make the focus of float 32 be located the center department, is favorable to siphon tube head 331 to keep vertical state to make siphon tube head 331's bottom can stretch into under the liquid level, avoid siphon to break.

Further, in order to prevent the elbow 333 and the straight pipe 334 in the drain pipe 33 from moving along with the float 32 to affect the drainage effect, the elbow 333 is fixed with the box body 1, and the elbow 333 and the straight pipe 334 are prevented from being affected by the float 32, so that the stability of the drainage mechanism is ensured.

Alternatively, the straight pipe 334 and a portion of the bent pipe 333 may be provided outside the tank 1 to facilitate connection with a sewer.

In other embodiments, the straight pipe 334 and the bent pipe 333 may be provided inside the tank body 1, and only the bottom end of the straight pipe 334 protrudes outside the tank body 1 to be connected to a sewer.

The laundry treating apparatus requires draining after washing (including main washing and rinsing) is finished, and generally performs a dehydration process after the draining is finished, but requires continuous draining although the amount of water generated during the dehydration process is not large. In order to continuously perform siphon drainage between washing and dewatering and avoid water replenishment to the drain pipe 33 for multiple times, in this embodiment, the dewatering process is started when all the water in the outer tub 2 is drained in the drainage stage (at this time, water is present in the connection pipe 36 and the communication container 31), so that at the beginning of the dewatering process, water in the communication container 31 can avoid siphon interruption, and water generated after dewatering starts enters the communication container 31 to be drained, so that washing drainage and dewatering drainage can be connected to avoid siphon interruption.

In order to avoid the situation that after the liquid level in the communicating container 31 is reduced, the siphon head 331 is completely attached to the bottom surface of the communicating container 31 to block siphons, at least two protrusions are arranged on the bottom end surface of the siphon head 331 at intervals and can be abutted against the bottom surface of the communicating container 31 when the liquid level in the communicating container 31 is low, so that a gap is formed between the bottom end surface of the siphon head 331 and the bottom surface of the communicating container 31, and the gap can always ensure that the inside of the siphon head 331 is communicated with the inside of the communicating container 31.

In addition, the end face of the bottom of the siphon head 331 is provided with a protrusion, so that siphon can be interrupted when the amount of water is abnormally small, and after siphon interruption, the outer cylinder 2 and the drain pipe 33 are communicated through the gap, so that the air pressure in the drain pipe 33 is the same as the air pressure in the outer cylinder 2, and the defect that water cannot be filled fully because siphon (siphon is not broken) is automatically generated due to low air pressure in the drain pipe 33 and rising water level in the communicating container 31 when water is filled into the outer cylinder 2 again can be avoided.

Further, a water collecting recess 311 is formed in the bottom surface of the communicating container 31, and the water collecting recess 311 is located right below the siphon head 331. By providing the water collection recess 311, a small amount of water remaining in the communicating vessel 31 can be collected in the water collection recess 311 and discharged through the siphon head 331, thereby ensuring that all the water in the communicating vessel 31 is discharged.

Alternatively, the height of the bottom surface of the communicating container 31 may gradually decrease from the edge to the direction close to the water collecting recess 311, so as to guide the water and facilitate the water collection.

In order to facilitate accurate control of the dehydration timing, the laundry treating apparatus includes a controller, and the drain mechanism further includes a triggering member 372 and a sensing member 371. The trigger 372 is provided on the float 32 to vary in height with the float 32. The sensor 371 is disposed on the outer wall of the communicating container 31 and connected to the controller in a communication manner, the sensor 371 is flush with the lowest point of the outer tub 2, the sensor 371 is configured to be triggered by the trigger 372, and the controller is configured to start the dehydration process after the sensor 371 is triggered. Through the cooperation of response piece 371 and trigger 372 for the clothing treatment facility can begin to dewater when the liquid level in the intercommunication container 31 reduces to the minimum parallel and level with urceolus 2, because of urceolus 2 and intercommunication container 31 intercommunication, at this moment, the water in the urceolus 2 is whole to be discharged, so that in time dewater, avoid siphon to break.

In some embodiments, the height of the sensor 371 may be lower than the lowest point of the outer tub 2, but should be higher than the lowest point of the communicating vessel 31 to ensure that water is in the communicating vessel 31 when dehydration starts.

Illustratively, the sensing element 371 is a reed switch and the triggering element 372 is a magnet. The magnet and the reed switch do not need to be in contact, and the magnet can trigger the reed switch in the communicating container 31 to avoid opening holes in the communicating container 31.

In other embodiments, the sensing element 371 and the triggering element 372 may have other structures, for example, the sensing element 371 is a hall element, in short, as long as the triggering element 372 can trigger the sensing element 371, so that the sensing element 371 transmits a signal to the controller to start the dewatering process in time.

Further, the drainage mechanism further includes a connection pipe 35, and the connection pipe 35 is communicated with the water outlet of the valve body 341. Alternatively, the connection pipe 35 is a bellows pipe which does not collapse during siphon discharge, and can provide siphon power, and particularly, siphon discharge with a low flow rate can be realized when the water level in the communication tank 31 is low.

In this embodiment, the water replenishing assembly 38 includes a water replenishing pipe 382 and a control valve 381, the water replenishing pipe 382 is used for replenishing water to the water discharging pipe 33, and the controller is used for controlling the on-off of the water replenishing pipe 382 so as to start or stop the water replenishing.

When the water is drained, water needs to be added into the drain pipe 33, so that the water level above the on-off valve 34 in the straight pipe 334 reaches a preset water level, and the shutter 342 can open the drain pipe 33 under the action of the water pressure. In order to stop the water supply in time to avoid water waste, the control valve 381 can control the water supply amount by controlling the opening time.

Specifically, the laundry treatment apparatus experimentally measures the water replenishment time when the liquid level in the straight pipe 334 reaches a preset water level before leaving the factory, and stores the preset water replenishment time (e.g., 3S) into the controller by time data. When the drainage is started, the control valve 381 is opened to make the water replenishing pipe 382 replenish water into the drainage pipe 33, and is closed after the control valve 381 is opened for a preset water replenishing time, so that the waste of water resources is avoided.

Further, the preset water replenishing time can be determined according to the data of the time of tap water under the lowest water pressure, so that the shutter 342 can be opened within the preset water replenishing time when the pressure of the tap water in the household of a user is lower.

When the clothes treatment equipment is used for the first time, the straight pipe 334 has no water, and the water replenishing quantity is large when the water is replenished to the preset water level H for the first time; when the clothes treating apparatus needs to drain water again, the water remained after the last drainage remains in the straight pipe 334, so that the water amount needing to be supplemented is less than the water amount for supplementing water for the first time. Therefore, two preset water replenishing times can be stored in the controller, wherein one preset water replenishing time is the first preset water replenishing time during the first use, and the other preset water replenishing time is the second preset water replenishing time during the second use and the subsequent use.

The water discharge process of the laundry treating apparatus in this embodiment is as follows:

when the laundry treating apparatus is used for the first time, the inside of the drain pipe 33 is completely free of water, and the shutter 342 closes the bottom end of the drain pipe 33 by the elastic member.

After the washing process is started, the water level in the communicating container 31 is synchronously raised as water is continuously added into the outer tub 2, the float 32 is raised as the water level in the communicating container 31 rises, and the siphon head 331 is submerged in the water. When the water supply into the outer cartridge 2 is completed, the hose 332 is wound around the float 32.

After the main washing is finished and the water needs to be drained, the controller first energizes the sensor 371 and opens the control valve 381, so that the water replenishing assembly 38 replenishes water into the drain pipe 33. After the water level in the straight pipe 334 reaches the preset water level H, the shutter 342 is pushed open by the water pressure, and the drain pipe 33 is communicated with the sewer to trigger the siphon effect.

Along with the descending of the drainage float 32, the triggering part 372 is driven to trigger the sensing part 371, the sensing part 371 sends a signal to the controller, and the controller starts a dewatering program according to the received signal. The water generated by the dehydration is introduced into the communicating vessel 31 so as to be discharged by the siphon effect.

When the water in the communicating vessel 31 is completely discharged, the water in the drain pipe 33 gradually decreases. After the liquid level in the drain pipe 33 is reduced to the preset water level H, the pressure of the water pressure on the shutter 342 is smaller than the pushing force of the elastic member on the shutter 342, the shutter 342 closes the drain pipe 33 under the action of the elastic member, the drainage is finished, and a section of water column is reserved in the straight pipe 334.

It is understood that the main washing is finished and then the draining and dewatering are performed, the dewatering is finished and then the rinsing is performed at least twice, the draining and dewatering are performed after each rinsing is finished, and the procedures of the draining and dewatering are the same as the above-mentioned procedures, and are not described in detail herein.

The straight pipe 334 is provided with a section of water column after the first drainage is finished, the water column can block dirty air in a sewer from entering a room through the clothes treatment equipment to keep the air of a family fresh on one hand, and on the other hand, the siphon effect can be triggered by only supplementing little water when siphon drainage is triggered each time.

It should be noted here that the water column retained in the straight pipe 334 is substantially different from the residual water retained in the existing drum washing machine. 500-600 ml of water remains in the thread scraps filter and the pipeline after the existing drum washing machine with upper drainage finishes drainage, and the remaining water can be mixed with the water in the main washing stage when the next washing is carried out, but the residual water column in the invention does not participate in the washing completely, thereby being more sanitary.

The clothes treatment equipment of the embodiment drains water through a siphon effect, and compared with draining pump drainage, the residual water in the outer barrel 2 and the communicating container 31 can be thoroughly drained, so that the clothes treatment equipment is ensured to be internally dry when not in use, bacteria breeding is reduced, and the clothes treatment equipment is more sanitary and healthier; can not generate blockage, does not need to be provided with a thread scrap filter or need manual cleaning, and greatly improves the product economy and convenience. The drainage does not need electric energy, can save the cost, the noise reduction too.

It should be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Numerous obvious variations, adaptations, and substitutions will occur to those skilled in the art without departing from the scope of the present invention. This need not be, nor should it be exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
