The washing machine is widely used in daily life as a household appliance, replaces the traditional mode of washing clothes by hands, and greatly liberates the hands of people.

Based on this, as shown in fig. 1, the present application provides a washing machine 10 including a cabinet 100, a tub 200, and a drum 300, the tub 200 being disposed in the cabinet 100, and the drum 300 being disposed in the tub 200.

With the above arrangement, when the laundry needs to be washed, the laundry is placed in the drum 300, then the washing machine 10 is started, the drum 300 starts to rotate to clean the laundry, after the washing is finished, the water in the drum 300 is automatically discharged to the outside of the cabinet 100, and then the drum 300 rotates again to perform the dewatering treatment on the laundry.

It can be understood that, in order to enable external water to enter the drum 300, a water inlet hole is formed on the outer tub 200, the washing machine 10 provided by the present application further includes a water inlet pipe 920, a water inlet end of the water inlet pipe 920 is used for communicating with an external water source, generally communicating with a water tap, a water outlet end of the water inlet pipe 920 is communicated with the water inlet hole, and due to the numerous through holes formed in the drum 300, water in the water inlet pipe 920 can enter the outer tub 200 through the water inlet hole, and then enter the inner tub through the through holes. An external water source is communicated with the drum 300 through the water inlet tube 920 to introduce water into the drum 300.

After the washing machine 10 dehydrates the laundry, although most of the moisture is removed from the laundry, the laundry is very wet and cannot be put on immediately.

In order to solve the above problem, as shown in fig. 2, the washing machine 10 of the present application further includes a drying air duct 400, as shown in fig. 3, a heating device 500 and a fan 600, wherein the drying air duct 400 is formed between the tub 200 and the cabinet 100 (not shown in the figure), and two ends of the drying air duct 400 are respectively communicated with the drum 300 and form a circulation loop; the heating device 500 is disposed in the drying air duct 400, and the blower 600 is disposed in the drying air duct 400.

In this way, after the washing machine 10 finishes dewatering, the fan 600 and the heating device 500 are started, air is driven by the fan 600 to flow between the drying air duct 400 and the drum 300 in a circulating manner, and since the air is heated when passing through the heating device 500, hot air flows between the drum 300 and the drying air duct 400 in a circulating manner, so as to dry the clothes in the drum 300. So that the user can put on the laundry after the laundry is washed by the washing machine 10.

It can be understood that, as shown in fig. 3, the blower 600 may be disposed at the air inlet end of the drying duct 400, so as to better suck out the air in the drum 300.

The heating device 500 may be a heating pipe, but may also be any other suitable heating device 500, which is not limited in this application.

In addition, in order to drive air to flow between the drying air duct 400 and the drum 300 by using the fan 600, the fan 600 includes a motor and an impeller, the motor is fixed in the drying air duct 400, and the impeller is in transmission connection with the motor. The impeller is driven by a motor to rotate, and the impeller drives air to flow between the drying air duct 400 and the drum 300.

For example, in order to connect the drying air duct 400 with the drum 300 and form a circulation loop, as shown in fig. 4, a drying through hole 210 is formed on the outer tub 200, and the drying through hole 210 is connected with the drum 300, for example, the drying through hole 210 may be formed at a rear portion of the outer tub 200 along an axial direction thereof, an air inlet end of the drying air duct 400 is fastened at the drying through hole 210, so that the drying through hole 210 is connected with the drying air duct 400, an air outlet end of the drying air duct 400 is fastened at a position of a door seal of the washing machine 10 or a front portion of the outer tub 200, and a through hole is formed on a side wall or the door seal of the outer tub 200, so that the air inlet end and the air outlet end of the drying air duct 400 are respectively connected with two ends of the outer tub 200 along the axial direction thereof.

Because the inner cylinder is rotatably disposed in the outer cylinder 200 and has a plurality of water inlets (when the laundry is stirred, water can enter the drum 300 through the water inlets), the water inlets can serve as a pore passage for communicating the drying air duct 400 with the drum 300, thereby achieving communication between the drying air duct 400 and the drum 300.

In addition, along the direction parallel to the axis of the drum 300, since the drying through hole 210 is opened at the rear end of the outer tub 200, and the air inlet end of the drying air duct 400 is connected to the front end of the outer tub 200, hot air can enter from the front end of the drum 300, pass through the whole drum 300, and then be discharged from the rear end of the drum 300, so that the hot air can be fully contacted with the clothes, and the drying efficiency is improved.

Since the tub 200 is cylindrical, it is necessary to prevent air leakage at a connection position of the air inlet end of the drying duct 400 and the drying through hole 210 when the air inlet end is communicated with the drying through hole. Therefore, as shown in fig. 5, the washing machine 10 provided by the present application further includes a protrusion 800, the protrusion 800 is fixed on the outer wall of the outer tub 200 and surrounds the drying through hole 210 for a circle, a groove 810 is formed on the protrusion 800, the groove 810 surrounds the drying through hole 210 for a circle, and the edge of the air inlet end of the drying air duct 400 is clamped in the groove 810.

Therefore, when the drying air duct 400 is installed on the outer tub 200, the air inlet end of the drying air duct 400 can be inserted into the groove 810 from top to bottom (in the direction of the arrow in fig. 5), the air inlet end of the drying air duct 400 is clamped on the outer tub 200 by using the groove 810, and the protrusion 800 surrounds the drying through hole 210 for a circle, so that when the air inlet end of the drying air duct 400 is clamped in the groove 810, the protrusion 800 can prevent the wind from flowing out from the joint of the air inlet end of the drying air duct 400 and the outer tub 200, and the wind leakage at the joint of the air inlet end of the drying air duct 400 and the outer tub 200 can be avoided.

It should be explained that the air inlet end of the drying air duct 400 is clamped in the groove 810, which means that the air duct wall of the air inlet end of the drying air duct 400 extends into the groove 810.

In order to facilitate the clamping of the air inlet end of the drying air duct 400 in the groove 810, the notch of the groove 810 faces the side of the outer tub 200 far away from the roller 300, so that the air inlet end of the drying air duct 400 can be clamped in the groove 810.

Illustratively, to form the drying duct 400, as shown in fig. 6, the washing machine 10 provided by the present application includes a first duct section 410 and a second duct section 420, the first duct section 410 extends in a direction perpendicular to an axis of the drum 300 (X direction in fig. 6), the second duct section extends in a direction parallel to the axis of the drum 300 (Y direction in fig. 6), a first end of the first duct section 410 communicates with the drum 300, a second end of the first duct section 410 communicates with a first end of the second duct section 420, and a second end of the second duct section 420 communicates with the drum 300.

Since the first pipe section 410 extends in a direction perpendicular to the axis of the drum 300, it is more convenient to clamp the first end of the first pipe section 410 (the air inlet end of the drying duct 400) to the outer wall of the outer tub 200, in which case the first pipe section 410 can serve as a reversing channel.

In addition, since the second pipe segment 420 extends along a direction parallel to the axis of the drum 300, i.e., along a straight line, the second pipe segment 420 is not bent, so that the impact between the hot air and the inner wall of the second pipe segment 420 is reduced, the loss of the air volume is reduced, the drying efficiency is improved, and the material for forming the second pipe segment 420 can be saved.

In this case, as shown in fig. 6, the blower 600 may be disposed in the second pipe section 420, and in order to save space, the blower 600 may be horizontally disposed in the second pipe section 420 such that the axis of the impeller is perpendicular to the axis of the drum 300, so that the size of the washing machine 10 in the height direction may be reduced, and the washing machine 10 may be miniaturized as a whole.

In addition, the first pipe segment 410 and the second pipe segment 420 may be formed as an integral structure, so that the connection strength between the two can be enhanced.

Or, the first pipe section 410 and the second pipe section 420 may be of a separate structure, and on this basis, in order to facilitate the connection between the first end of the second pipe section 420 and the second end of the first pipe section 410 and prevent air leakage at the connection between the two, as shown in fig. 7, a protruding portion 411 is provided at the second end of the first pipe section 410, the protruding portion 411 is provided around the second end of the first pipe section 410, a recessed portion 412 is provided on the protruding portion 411, the recessed portion 412 is provided around the second end of the first pipe section 410, and the first end of the second pipe section 420 is extended into the recessed portion 412.

Therefore, when the second pipe section 420 is connected to the first pipe section 410, the first end of the second pipe section 420 can be inserted into the recess 412 from top to bottom (in the X direction in fig. 7), the recess 412 is used to clamp the first end of the second pipe section 420 to the first pipe section 410, and the protrusion 411 surrounds the second end of the first pipe section 410 for a circle, so that when the first end of the second pipe section 420 is clamped to the recess 412, the protrusion 411 can block the wind from flowing out from the connection between the first end and the second end, thereby reducing the loss of wind volume and saving energy.

It can be understood that the fitting between the recess 412 and the second pipe section 420 is only for preventing air leakage, and in order to stably connect the first pipe section 410 and the second pipe section 420 together, the first pipe section 410 and the second pipe section 420 can be fixed together by means of screw fastening, for example, as shown in fig. 8, a plurality of fixing plates 421 are provided on the outer wall of the second pipe section 420, screw holes are opened on the fixing plates 421, and the fixing plates 421 are fixed on the first pipe section 410 by means of screw fastening and the like, so as to fix the first pipe section 410 and the second pipe section 420 together.

On this basis, in order to facilitate the placement of the fan 600, as shown in fig. 9, the second pipe section 420 includes an upper cover 422 and a lower cover 423, the lower cover 423 is fixed to the first pipe section 410, and the upper cover 422 and the lower cover 423 are fastened to form the second pipe section 420. Set up second pipe section 420 into two parts, so when setting up fan 600, can separate the back with lower cover 423 and upper cover 422, then set up fan 600 on lower cover 423, again with upper cover 422 lock on lower cover 423 to realize fan 600's installation, when dismantling, take off upper cover 422, alright take out fan 600, so be convenient for fan 600's dismantlement and installation.

It can be understood that, in order to facilitate the setting of the fan 600 and enable the fan 600 to drive the air to flow in the second pipe segment 420, the motor may be fixed on the upper cover 422, the impeller is disposed on one side of the motor close to the lower cover 423, and then the air inlet of the first pipe segment 410 is disposed on the lower cover 423, so that the impeller is directly opposite to the air inlet of the first pipe segment 410, thereby ensuring the normal implementation of the drying function.

Along with the increase of the number of times of drying, on fan 600 and can deposit debris such as batting in the stoving wind channel 400, if can not in time clear up, can make stoving wind channel 400 block up, fan 600 load aggravates to influence the realization of stoving function.

It can be understood that, in order to extend the spraying column 730 into the drying air duct 400, the shape of the spraying column 730 may be adjusted according to actual conditions, for example, the spraying column 730 may be designed according to the extending direction, the bending degree, and the like of the drying air duct 400, so as to extend into the drying air duct 400.

On the basis, in order to form the spray column 730, as shown in fig. 14, the spray column 730 includes a first housing 731 and a second housing 732, and a first groove 7311 is opened inside the first housing 731; the second housing 732 has a second groove 7321 (facing the first groove 7311) formed therein, the second housing 732 is fastened to the first housing 731, for example, by fastening with screws or gluing, and the first groove 7311 is fastened to the second groove 7321 to form the flow channel 720.

Therefore, when the spray column 730 is processed, two shells (the first shell 731 and the second shell 732) can be processed, and then the first shell 731 and the second shell 732 are fastened together to form the spray column 730, so that the spray column 730 with complex lines can be processed conveniently, and a flow channel is conveniently arranged in the spray column 730 with complex lines, thereby reducing the processing difficulty.

Certainly, the spray post 730 can also be integrally formed, so that the overall structural strength of the spray post 730 can be increased, and because the spray post 730 is of an integrally formed structure, no gap is formed in the whole spray post 730 except for the spray holes 711, so that water leakage of the spray member 700 at other positions besides water spraying at the spray holes 711 can be avoided.

Alternatively, the spray assembly 700 may also include a spray ball, with a plurality of spray holes 711 disposed around the center of the spray ball to form the spray hole group 710. Of course, the spray member 700 may have any other suitable shape, which is not specifically disclosed herein.

In some embodiments, as shown in fig. 11, the spraying member 700 is disposed on the air inlet side of the fan 600 such that at least a portion of the spraying member 700 protrudes into the air inlet of the impeller, and at least a portion of the spraying member 700 has spraying holes 711. Therefore, the spraying member 700 can flush the impeller, and since the spraying member 700 is located on the air inlet side of the fan 600, when the spraying member 700 sprays water, the water on the impeller can be thrown onto the inner wall of the drying air duct 400 under the driving of the impeller, and since the rotating speed of the impeller is high, the speed of the water thrown into the drying air duct 400 is high, and the drying air duct 400 can be better cleaned.

Of course, the spraying member 700 may be disposed on the air outlet side of the fan 600.

In some embodiments, as shown in fig. 15, the spraying member 700 extends into the drying duct 400 through the drying through hole 210, and at least a portion of the spraying hole 711 faces the protrusion 800. In this way, the water sprayed from the spraying holes 711 can also clean the protrusions 800 to remove dirt at the contact position between the protrusions 800 and the air inlet end of the drying air duct 400.

On this basis, in order to control the opening and closing of the spraying member 700, as shown in fig. 16, the washing machine 10 of the present application further includes a spraying pipe 900 and a water inlet valve 910, the spraying pipe 900 is fixedly connected with the spraying member 700, a water outlet end of the spraying pipe 900 is communicated with the flow passage 720, and a water inlet end of the spraying pipe 900 is used for being communicated with an external water source; the water inlet valve 910 is connected to the spray pipe 900 and is used for controlling the spray pipe 900 to be opened or closed.

Through the arrangement, the water inlet valve 910 is used for controlling the on-off of the spraying pipeline 900, and the spraying pipeline 900 is communicated with the flow channel 720, so that the water inlet valve 910 can control the spraying and non-spraying of the spraying piece 700, so that the spraying piece 700 sprays water when in proper time and does not spray water when not in proper time.

For example, when the heating device 500 is activated, that is, when the washing machine 10 enters the drying mode, the water inlet valve 910 is closed, and the spraying member 700 cannot spray water, so as to ensure the normal operation of the drying mode of the washing machine 10, and ensure the drying efficiency and effect thereof.

For another example, after the dewatering mode and/or the draining mode are/is started and/or before the drying program is started, the blower 600 is started, the water inlet valve 910 is opened to flush the impeller and the drying air duct 400, so that other operation modes of the washing machine 10 are not affected when water is sprayed each time. For example, the water can be sprayed for 3-4 seconds at a time.

Wherein, the spray pipe 900 and the spray member 700 may be an integrally formed structure. Therefore, the two structures are integrated, the pipeline connection is not needed, the manual processing cost is reduced, and in addition, the structural strength of the two structures can be increased. Of course, the spray pipe 900 and the spray member 700 may be separate structures, and the spray pipe 900 and the spray member 700 are separately processed and then communicated together.

On this basis, since inlet pipe 920 needs to be in communication with a water source, and shower pipe 900 also needs to be in communication with a water source, as shown in fig. 17, the inlet end of shower pipe 900 is in communication with inlet pipe 920. The water inlet end of the spraying pipeline 900 is communicated with the water inlet pipe 920, so that the water inlet pipe 920 has two purposes by one pipe when water is fed, and the arrangement of pipelines is reduced.

In this case, in order to facilitate the communication of the water inlet end of the shower pipe 900 to the water inlet pipe 920, the water inlet pipe 920 and the shower pipe 900 may be fixed together, and the connection stability therebetween may be ensured.

Since the water inlet pipe 920 is generally connected to a tap water source, the tap water may have a high water pressure, and as shown in fig. 18, at least one pressure relief hole 740 is formed in the spray member 700, and the pressure relief hole 740 is connected to the flow passage 720. Through setting up pressure release hole 740, avoid getting into the too high water pressure in the runner 720, reduce the noise of collision between water and fan 600, water and the inner wall of stoving wind channel 400.

It will be appreciated that the pressure relief holes 740 may be made slightly larger, for example slightly larger than the spray holes 711, in order to have a good pressure relief effect.

The pressure relief hole 740 may be a circular hole or a square hole, which is not limited in this application.

For a clearer understanding of the operation principle of the washing machine 10 in the present application, the operation thereof will be described in detail below.

In washing, firstly, a washing process is performed to put the laundry in the drum 300, and then the washing machine 10 is started, water is introduced into the drum 300, and the drum 300 is rotated to wash the laundry.

After the washing is finished, a dewatering process is performed, the drum 300 rotates fast to dewater the clothes, in the dewatering process, the water inlet valve 910 and the impeller are opened, so that water in the water inlet pipe 920 enters the spraying pipeline 900 and further enters the spraying part 700, then the drying air duct 400 and the impeller are washed, and the washed water flows back into the drum 300 from outlets at two ends of the drying air duct 400 and is discharged to the outside.

After the dehydration process is completed, the water inlet valve 910 is closed, the spraying member 700 stops spraying water, at this time, the drying process is performed, and the impeller and the heating device 500 are activated, so that hot air circulates between the drum 300 and the drying duct 400 to dry the laundry in the drum 300.

Finally, after the drying process is completed, the washing machine 10 is turned off and the laundry is taken out.

The clothes are cleaned through three procedures of washing, dewatering and drying, so that the clothes are in a dry and clean state after being cleaned, and can be worn immediately.

The above description is only an embodiment of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions within the technical scope of the present disclosure should be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
