[0026] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0028] An embodiment of the present application provides a washer-dryer integrated machine to solve the problem in existing washer-dryers that sewage discharged from the washing machine easily flows back into the dryer during drainage, which will be explained below in conjunction with the accompanying drawings.

[0029] In the embodiments of the present application, Figure 1 As shown, the integrated washer-dryer 100 mainly includes a washing machine 10, a drying machine 20 and a drainage pipe assembly 30.

[0030] The washing machine 10 is used to wash and clean clothes. Figure 2 As shown, Figure 2 The washing machine 10 shown in the figure is a drum type washing machine 10, which is designed to imitate the principle of a hammer hitting clothes. When the drum rotates, it generates huge centrifugal force to perform repeated movements, and the laundry detergent and water work together to clean the clothes. The door of the washing machine 10 is set on the side of the box body, rather than the top of the box body, so that the space on the top of the box body can be used to accommodate other devices such as a dryer 20, and it is also convenient to embed the washing machine 10 into the wall to reasonably arrange the position of the washing machine 10, thereby saving the occupied space of the washing machine 10.

[0031] The washing machine 10 is also provided with a water inlet 12 and a first drain outlet 11, wherein the water inlet 12 can be divided into a hot water inlet 121 and a cold water inlet 122, so that hot water or cold water can be introduced to wash clothes as needed, and the sewage generated during the washing process is discharged through the first drain outlet 11.

[0032] like Figure 3As shown, the dryer 20 is arranged on the top of the washing machine 10, and the dryer 20 is mainly used to dry the clothes. The dryer 20 can be an electric heating drying device, that is, the air is heated by the heating element to enter the inner drum, and the air is heat-exchanged with the clothes in the inner drum to continuously discharge the moisture in the clothes, thereby drying the clothes. The dryer 20 can also be a heat pump drying device, that is, the heat pump drying device exchanges heat with the moisture in the clothes under the circulation of the compressor, condenser and other components, thereby continuously discharging the moisture in the clothes, thereby achieving the drying of the clothes.

[0033] In short, the type of dryer 20 can be flexibly selected according to needs, and this application does not make specific limitations. Of course, in other embodiments, the dryer 20 can also be configured with sterilization, disinfection, incense and other care functions to care for foreign objects and meet the needs of users.

[0034] The dryer 20 is generally also provided with a condenser and a water storage box 21. The moisture discharged from the clothes condenses into water droplets after contacting the condenser, and the water droplets then flow along the surface of the condenser into the water storage box 21. At the same time, a second drain port 211 is provided on the water storage box 21 to facilitate timely discharge of the condensed water.

[0035] like Figure 4 As shown, the drainage pipe assembly 30 is provided with a first water opening 311, a second water opening 321 and a third water opening 331. Figures 1 to 3 The first water opening 311 is connected to the first drain opening 11, the second water opening 321 is connected to the second drain opening 211, and the third water opening 331 is used to communicate with the external environment of the washing and drying integrated machine 100, and the specific external environment can be a floor drain, a drain tank, etc. Therefore, after the first drain opening 11 of the washing machine 10 and the second drain opening 211 of the drying machine 20 drain the water, the water is then drained to the floor drain, the drain tank, etc. through the drain pipe assembly 30.

[0036] Specifically, Figure 4 The drain pipe assembly 30 shown mainly includes a tee pipe 34, a first drain pipe 31, a second drain pipe 32 and a third drain pipe 33. The tee pipe 34 is fixed to the washing machine 10, one end of the first drain pipe 31 is provided with a first water opening 311, and the other end is connected to the tee pipe 34; one end of the second drain opening 211 is provided with a second water opening 321, and the other end is connected to the tee pipe 34; one end of the third drain pipe 33 is provided with a third water opening 331, and the other end is connected to the tee pipe 34.

[0037] Alternatively, in other embodiments, the drain pipe assembly 30 may also include only two drain pipes, one of which is provided with a first water opening 311 and a third water opening 331 at both ends, and the other drain pipe is provided with a second water opening 321 at one end, and the other end is directly connected to the side of the other drain pipe. In this way, only one floor drain can be used and the three-way pipe 34 can be saved.

[0038] In short, the specific structure of the drain pipe assembly 30 can be flexibly selected according to actual conditions.

[0039] It is understandable that, because both the washing machine 10 and the dryer 20 drain water through the drain pipe assembly 30, and because the drainage volume of the washing machine 10 is generally larger, the sewage discharged by the washing machine 10 may sometimes flow back into the dryer 20 due to insufficient drainage. Over time, stains in the sewage remain and mold, which will cause odor in the dryer 20, thereby causing user complaints.

[0040] Therefore, in this application, please combine Figure 1 , Figure 3 , Figure 5 and Figure 6 , a drain valve 40 is provided between the second drain port 211 and the second water outlet 321, and the drain valve 40 is a one-way valve, and the drain valve 40 allows the fluid to flow out from the second drain port 211, and prevents the fluid from flowing into the second drain port 211. That is to say, when the dryer 20 needs to be drained, the water in the dryer 20 can flow out from the second drain port 211 and flow into the drain pipe assembly 30, and finally flow into the external environment (such as a floor drain) from the third water outlet 331 of the drain pipe assembly 30. When the sewage in the drain pipe assembly 30 flows back to the second water outlet 321 and the drain valve 40 due to poor drainage, the drain valve 40 can prevent the sewage from flowing into the second drain port 211, that is, it can prevent the sewage from flowing back into the dryer 20, so as to avoid the situation where the stains in the sewage remain and mold and cause odor in the dryer 20.

[0041] It should be noted that the type of the drain valve 40 can be a spring-loaded one-way valve, a gravity-loaded one-way valve, a swing-type one-way valve, a plastic diaphragm one-way valve, etc., as long as the drain valve 40 allows the fluid to flow out of the second drain port 211 and prevents the fluid from flowing into the second drain port 211.

[0042] For example, optionally, in one embodiment, Figure 5 and Figure 6As shown, the drain valve 40 is a gravity-type one-way valve, and the drain valve 40 includes a valve body 41 and a valve core 42. The valve body 41 is provided with a valve cavity 411, and the valve cavity 411 has a first cavity opening 4111 connected to the second drain port 211, and a second cavity opening 4112 connected to the second water port 321; the valve core 42 is movably installed in the valve cavity 411, and when the water level in the valve cavity 411 rises, the valve core 42 approaches the first position under the buoyancy of the fluid; when the water level in the valve cavity 411 drops, the valve core 42 moves away from the first position under the action of its own gravity. Figure 6 As shown, when the valve core 42 is in the first position, the valve core 42 blocks the first cavity opening 4111 .

[0043] That is to say, when the sewage in the drain pipe assembly 30 enters the valve cavity 411 through the second water opening 321, the buoyancy of the sewage will drive the valve core 42 to rise until the valve core 42 rises to the first position, at which time the valve core 42 blocks the first cavity 4111, thereby preventing the sewage from entering the second drain port 211 and the dryer 20 through the first cavity 4111. When the water level in the valve cavity 411 drops, the valve core 42 will drop with the sewage under the action of its own gravity, at which time the valve core 42 moves away from the first position and opens the first cavity 4111, thereby ensuring that the condensed water in the dryer 20 can enter the valve cavity 411 through the second drain port 211 and the first cavity 4111, and then enter the drain pipe assembly 30 through the second water opening 321, thereby realizing the discharge of the condensed water in the dryer 20.

[0044] It can be understood that this embodiment sets the drain valve 40 as a gravity one-way valve, which can prevent the sewage in the drain pipe assembly 30 from flowing back into the dryer 20 without affecting the drainage of the dryer 20, and has a simple structure and is easy to produce.

[0045] Optionally, in one embodiment, as Figure 5 and Figure 6 As shown, the valve core 42 is disc-shaped, and the outer diameter of the valve core 42 is larger than the inner diameter of the first cavity 4111 and smaller than the inner diameter of the second cavity 4112. A stopper 43 is also provided at the second cavity 4112. When the water level in the valve cavity 411 drops, the valve core 42 moves away from the first position and approaches the second position under the action of its own gravity. Figure 5 As shown, when the valve core 42 is in the second position, the valve core 42 is supported on the limiting member 43.

[0046] It can be understood that in this embodiment, because the outer diameter of the valve core 42 is larger than the first cavity opening 4111 and smaller than the second cavity opening 4112, when the valve core 42 is in the first position, the valve core 42 can block the first cavity opening 4111 to prevent sewage from flowing into the first drain port 11 through the first cavity opening 4111; and when the valve core 42 is in the second position, the valve core 42 cannot completely cover the second cavity opening 4112 because its outer diameter is smaller than the second cavity opening 4112, and water discharged from the dryer 20 can flow into the second water port 321 and the drain pipe assembly 30 through the second cavity opening 4112, thereby draining the dryer 20.

[0047] Of course, in other embodiments, the outer diameter of the valve core 42 may also be no less than the inner diameter of the second cavity 4112. In this case, a blocking area and a water passing area may be set on the valve core 42. The blocking area is set corresponding to the first cavity 4111 and is used to block the first cavity 4111. The water passing area is set corresponding to the second cavity 4112 and is provided with a water passing hole. Water discharged from the dryer 20 can flow to the second cavity 4112 through the water passing hole, and then flow into the drain pipe assembly 30 through the second water opening 321.

[0048] It should be noted that the stopper 43 is used to limit the valve core 42 from moving further away from the first cavity 4111, so as to prevent the valve core 42 from moving into the drain pipe assembly 30 as the water level drops, and to ensure that the valve core 42 is always in the valve cavity 411. The specific structure of the stopper 43 is not limited, and can be rod-shaped, block-shaped, grid-shaped, etc., as long as it can support the valve core 42 and does not affect the connection between the second cavity 4112 and the second water port 321.

[0049] Optionally, in one embodiment, as Figure 5 and Figure 6 As shown, a guide portion 421 is also provided on the valve core 42, and the guide portion 421 is slidably connected to the valve body 41, and the guide portion 421 is used to make the valve core 42 move along the axial direction of the first cavity 4111, so as to avoid the valve core 42 from deviating to the left and right during the up and down movement, and thus failing to completely block the first cavity 4111, thereby improving the reliability of the drain valve 40.

[0050] It should be noted that the structure and position of the guide portion 421 can be set in a variety of ways, for example, the guide portion 421 can be a guide through hole, and the guide through holes are provided with at least two, and the guide through holes are arranged near the edge of the valve core 42. A guide slide bar is arranged at a position corresponding to the guide through hole in the valve body 41, and the guide slide bar penetrates into the guide through hole and extends parallel to the axial direction of the first cavity 4111. In this way, the valve core 42 can be guided to ensure that the valve core 42 moves along the axial direction of the first cavity 4111.

[0051] For example, in another embodiment, Figure 5 and Figure 6 As shown, the limiting member 43 has a guide hole 431 extending therethrough, and the guide hole 431 can be coaxially opposite to the first cavity opening 4111, and the guide portion 421 is rod-shaped and slidably installed in the guide hole 431, so that the up and down movement of the valve core 42 can also be guided and limited, and because the guide hole 431 is directly opened in the limiting member 43, there is no need to additionally set up other structures that cooperate with the guide portion 421, so that the structure of the drain valve 40 is relatively simple and easy to produce.

[0052] Further, such as Figure 5 As shown, because the stopper 43 is located at the second cavity 4112, when the valve core 42 is in the second position, the guide portion 421 also passes through the second water opening 321 and extends into the tube body of the drain pipe assembly 30. It can be understood that because the guide portion 421 extends into the tube body of the drain pipe, before the sewage in the drain pipe assembly 30 flows upward into the valve cavity 411, the guide portion 421 can form a certain flow resistance and disturbance to the sewage, thereby reducing the kinetic energy of the sewage, so that the sewage can enter the valve cavity 411 more smoothly, and avoid the situation where the sewage first flows to the first cavity 4111 before the valve core 42 closes the first cavity 4111.

[0053] Optionally, in one embodiment, as Figure 4 As shown, the drain pipe assembly 30 includes a tee pipe 34, a first drain pipe 31, a second drain pipe 32 and a third drain pipe 33. The tee pipe 34 is fixed to the washing machine 10. One end of the first drain pipe 31 is provided with a first water outlet 311, and the other end is connected to the tee pipe 34; one end of the second drain port 211 is provided with a second water outlet 321, and the other end is connected to the tee pipe 34; one end of the third drain pipe 33 is provided with a third water outlet 331, and the other end is connected to the tee pipe 34. That is, the three ports of the tee pipe 34 are respectively connected to the first drain pipe 31, the second drain pipe 32 and the third drain pipe 33. When the washing machine 10 discharges sewage, the sewage passes through the first drain port 11, the first water outlet 311, the first drain pipe 31, the tee pipe 34 and the third drain pipe 33 in sequence, and finally flows to a specific drainage position such as a floor drain or a sink through the third water outlet 331. When the dryer 20 discharges condensed water, the condensed water passes through the second drain port 211, the drain valve 40, the second water port 321, the second drain pipe 32, the three-way pipe 34 and the third drain pipe 33 in sequence, and finally flows to a specific drainage location such as a floor drain or a sink through the third water port 331.

[0054] What should be emphasized in the present embodiment is that the second drain pipe 32 extends in a bent shape, so that the sewage flowing into the second drain pipe 32 can be buffered to a certain extent through the bending position of the second drain pipe 32, so that the water level in the second drain pipe 32 and the valve cavity 411 can rise smoothly, thereby preventing the sewage from directly impacting the first cavity opening 4111 before the valve core 42 closes the first cavity opening 4111.

[0055] It should be noted that the bending mode of the second drain pipe 32 can be flexibly set according to needs. For example, in one embodiment, Figure 4 As shown, the second drain pipe 32 includes a first vertical section 322, a first inclined section 323 and a second vertical section 324 which are connected in sequence. The first vertical section 322 and the second vertical section 324 both extend along the direction of gravity, and one end of the first vertical section 322 is connected to the three-way pipe 34, and the other end is connected to the first inclined section 323; one end of the second vertical section 324 is provided with a second water outlet 321, and the other end is connected to the first inclined section 323; the first inclined section 323 extends obliquely between the first vertical section 322 and the second vertical section 324, so that bends are formed between the first inclined section 323 and the first vertical section 322, and between the first inclined section 323 and the second vertical section 324.

[0056] It can be understood that the first vertical section 322 and the second vertical section 324 are conducive to the condensed water in the dryer 20 to flow quickly into the drain pipe assembly 30, making the drainage smoother; the first inclined section 323 can make the second drain pipe 32 form at least two bends, thereby forming a buffer for the upwelling sewage, and the overall structure of the second drain pipe 32 is relatively simple and easy to produce.

[0057] Optionally, in one embodiment, as Figure 1 As shown, the washing machine 10 is also equipped with a water inlet valve 13, and two water inlet valves 13 are provided, one of which is a hot water inlet valve 131 and the other is a cold water inlet valve 132. The two water inlet valves 13 are arranged side by side along the width direction of the washing machine 10, and the first inclined section 323 of the second drain pipe 32 is inclined toward the side away from the water inlet valve 13, for example, Figure 1 In the structural scheme shown in FIG. 1 , the second vertical section 324 of the second drain pipe 32 is located on the left side of the water inlet valve 13, and the first inclined section 323 is inclined to the left. It can be understood that this can avoid the water inlet valve 13, thereby preventing the water inlet pipe and the drain pipe from being too close or interfering with each other, and facilitating the assembly of the water inlet pipe and the drain pipe assembly 30.

[0058] Furthermore, in one embodiment, if Figure 4As shown, the third drainage pipe 33 includes a second inclined section 332 and a third vertical section 333 connected to each other, one end of the second inclined section 332 is connected to the three-way pipe 34, and the other end is inclined downward and connected to one end of the third vertical section 333, and the other end of the third vertical section 333 is provided with a third water outlet 331. It can be understood that the second inclined section 332 can buffer the formation of the upwelling sewage, further reduce the kinetic energy of the sewage, and avoid the situation where the sewage quickly upwells and flows into the first cavity 4111 before the valve core 42 blocks the first cavity 4111; the third vertical section 333 can enable the sewage or condensed water to be discharged quickly, making the drainage smoother.

[0059] Optionally, in one embodiment, the integrated washing and drying machine 100 further includes a main control board (not shown), which is at least used to control the first drain port 11 to switch between a drain state and a water-stopping state. Specifically, a second drain valve (not shown) can be provided at the first drain port 11 in the washing machine 10, and the second drain valve is connected to the main control board for communication, which can be wireless communication or wired communication. The main control board controls the opening and closing of the second drain valve, and when the second drain valve is opened, the first drain port 11 switches to a drain state capable of draining water; when the second drain valve is closed, the first drain port 11 switches to a water-stopping state that prevents sewage from being discharged.

[0060] like Figure 3 As shown, the dryer 20 is also provided with a water storage box 21, a second drain port 211 is provided at the bottom of the water storage box 21, and a liquid level sensor 50 is provided in the water storage box 21, and the liquid level sensor 50 is connected to the main control board for communication, which can be wireless communication or wired communication. The liquid level sensor 50 is used to send a closing signal to the main control board when the water level in the water storage box 21 reaches a preset value, so that the main control board controls the second drain valve to switch to a closed state, thereby switching the first drain port 11 to a water-stopping state.

[0061] Specifically, in this embodiment, when the washing machine 10 is draining water and the amount of water discharged is large, causing the valve core 42 to block the first cavity 4111, the water level in the water storage box 21 will continue to rise as the condensed water continues to gather. When the water level in the water storage box 21 rises to a preset value, the liquid level sensor 50 will be triggered and send a closing signal to the main control board. The main control board controls the second drain valve in the washing machine 10 to close, so that the first drain port 11 is switched to a water stop state, and the washing machine 10 no longer continues to drain water. At this time, the water level in the valve cavity 411 will gradually drop, and the valve core 42 will open the first cavity 4111 as the water level drops, so that the condensed water in the water storage box 21 is discharged in time, and the condensed water is prevented from overflowing from the water storage box 21 into the drying cavity of the dryer 20.

[0062] Furthermore, within the first time after the washing machine 10 stops draining (for example, the first time may be 20 seconds), if the water level in the water storage box 21 reaches the preset value twice, it means that the water storage box 21 is not draining smoothly. At this time, an alarm for poor drainage may be issued, and the first drain port 11 of the washing machine 10 is kept in a water-stopping state, prompting the user to perform manual intervention and confirmation according to the processing plan in the instruction manual.

[0063] Furthermore, in order to improve the drainage efficiency and prevent the washing machine 10 from stopping drainage for too long, the main control board can also actively control the second drain valve in the washing machine 10 to switch to an open state after a certain period of time, so that the washing machine 10 continues to drain.
