As shown in fig. 1, the ironing machine 01 comprises a machine body 20, a water tank 30, a two-way box 10 of the ironing machine, a heating pan 40, an ironing head or a steam outlet, which are arranged in the machine body and communicated with each other in sequence, wherein cold water is filled in the water tank 30. As shown in fig. 2, cold water in the water tank 30 enters the heating pan 40 through the two-way box 10. The heating pan 40 is used for heating cold water, and the cold water is heated in the heating pan 40 to form hot water and hot steam. The machine body is provided with an air outlet 11, the air outlet 11 is connected with the ironing head or a steam outlet through a hose, and hot steam enters the ironing head or the steam outlet and is discharged from the ironing head or the steam outlet to perform ironing operation.

As shown in fig. 1 and 4, a two-way cartridge 10 for an ironing machine according to one embodiment of the present application is shown. The two-way box 10 of the ironing machine is connected with the water tank 30 and the heating pan 40. As shown in fig. 2 and 3, in the ironing machine 01, the two-way box 10 of the ironing machine is used for communicating the water tank 30 and the heat-generating pot 40, so that the cold water in the water tank 30 enters the heat-generating pot 40 through the two-way box 10 of the ironing machine, and the hot water and/or the hot steam in the heat-generating pot 40 are prevented from flowing back into the water tank 30. The specific structure of the two-way box 10 of the ironing machine is as follows.

As shown in fig. 5, the two-way box 10 of the ironing machine includes a box body 100, a box cover 200, and a flap 300. The cartridge 100 includes sidewalls 110 and a top wall 120. The top wall 120 is opened with a first opening 121. The first opening 121 is used to facilitate the installation of the swing piece 300 into the case 100; after the swing piece 300 is mounted in the case body 100, the cover 200 is closed over the first opening 121. The sidewall 110 is provided with a water inlet 111 and a water outlet 112. In particular arrangements, the cartridge 100 includes side walls 110, a top wall 120, and a bottom wall 130. The side walls 110, the top wall 120 and the bottom wall 130 may be integrally formed by a casting process, or the side walls 110, the top wall 120 and the bottom wall 130 may be manufactured by an injection molding process. Of course, the cartridge 100 is not limited to the above-mentioned structure and manufacturing process, and other structures and manufacturing processes satisfying the requirements may be adopted.

As shown in fig. 2, 3 and 6, the flap 300 is provided inside the case 100, and the flap 300 can swing inside the case 100 toward or away from the water inlet 111. The flap 300 will cover the inlet 111 when it swings to a maximum extent towards the inlet 111. In this way, the flap 300 can be used to control the opening and closing of the water inlet 111. When no external force is applied, the flap 300 naturally hangs down and is spaced from the sidewall 110, and gaps are formed between the flap 300 and the water inlet 111 and between the flap 300 and the water outlet 112, and the water inlet 111 is opened. When an external force (for example, the pressure of cold water entering the water inlet 111 from the water tank 30 and/or the pressure of hot water and hot steam reversely flowing from the heat-generating pot 40 to the water outlet 112) is applied toward the water inlet 111, the flap 300 can swing with respect to the top wall 120, and when the flap 300 swings toward the water inlet 111 to the maximum extent, the flap 300 covers the water inlet 111 so that the water inlet 111 is closed. The specific working process is as follows: when no external force is applied, the flap 300 naturally droops, the flap 300 is spaced apart from the sidewall 110, the water inlet 111 is opened, and cold water enters from the water inlet 111. The swinging piece 300 swings toward the water outlet 112 under the hydraulic pressure of the cold water but does not cover the water outlet 112, so that the cold water enters the box body 100 of the two-way box 10 and is then discharged from the water outlet 112. When hot water flows backwards, hot water and/or hot steam enters the box body 100 from the water outlet 112, the swinging piece 300 swings towards the water inlet 111 under the pressure action of the hot water and/or the hot steam, and the swinging piece 300 covers the water inlet 111 when swinging to the maximum amplitude under the pressure action, so that the hot water and/or the hot steam is prevented from overflowing from the water inlet 111 and even flowing backwards to the water tank 30. Therefore, the water inlet 111 can be opened and closed by arranging the swinging sheet 300, so that hot water and/or hot steam can be prevented from overflowing from the water inlet and even flowing into the water tank 30, the water tank 30 of the ironing machine 01 can be always kept in a cold water state, and the customer experience and the safety of the ironing machine 01 are improved.

In addition, when the air outlet of the iron head or the steam outlet is not smooth (for example, when the iron head is attached to the clothes during ironing clothes), the hot water and/or the hot steam of the heat-generating pot 40 also reversely flow into the box body 100, and the pendulum piece 300 swings toward the water inlet 111 under the pressure of the hot water and the pressure of the hot steam reversely flowing in the heat-generating pot 40. When the swing is maximum, the flap 300 covers the water inlet 111, so that the water inlet 111 is closed. After the swinging piece 300 is covered on the water inlet 111, the hot water and/or the hot steam flowing reversely from the heating pot 40 continuously enters into the box body 100, so that the pressure in the box body 100 can be gradually increased, the air pressure of the water outlet 112 and the air outlet of the ironing machine 01 is increased, the automatic pressurization effect of the ironing machine is realized, the spraying pressure of the hot steam is improved, the ironing machine 01 can be used for hanging ironing and ironing, and the application range and the ironing effect of the ironing machine 01 are expanded.

In addition, as described above, as the swing piece 300 continuously swings, the scale caused by the backflow of the hot water continuously flows, thereby preventing the scale from blocking the swing piece 300 and blocking the water inlet 111, and further improving the working stability and reliability of the ironing machine.

As shown in fig. 6, in one embodiment, the extending direction of the bottom wall 130 and the extending direction of the top wall 120 form a first included angle θ, and the height of the bottom wall 130 at the end close to the water inlet 111 is greater than the height of the bottom wall 130 at the end close to the water outlet 112 along the direction from the side wall 110 to the top wall 120, so that the bottom wall 130 is disposed obliquely with respect to the top wall 120. In this case, the water outlet 112 is located at the lowest position of the box body 100, so that on one hand, the entry of cold water can be facilitated; on the other hand, the inclined bottom wall 130 helps to quickly discharge the scale flowing back into the box 100 with the hot water through the water outlet 112, and prevents the scale from being accumulated in the box 100, which is beneficial to the fact that the scale generated by the heating pan 40 after a long time of operation will quickly leave the box 100 instead of being accumulated in the box 100 although the hot water flows back into the box 100, which reduces the probability that the swinging piece 300 is stuck by the scale and cannot swing.

In order to ensure smooth discharge of scale, the first angle θ may be, specifically, 15 ° to 25 °. In the two-way box 10 of the ironing machine, the first included angle theta is limited to be 15-25 degrees, so that the difference between the water inlet 111 and the water outlet 112 is large. The scale in the box body 100 can be smoothly flushed out of the box body 100 along with the cold water, so that the accumulation of the scale in the box body 100 is reduced, and the working stability and reliability of the water inlet 111 and the swinging piece 300 are ensured, thereby ensuring that the box body 100 is always in an environment with the best working effect; meanwhile, the swinging period of the swinging piece 300 is prevented from being prolonged due to the fact that the swinging piece 300 is clamped by water scale, the phenomenon that the swinging piece 300 swings to the water inlet 111 for a long time is avoided, the situation that the swinging piece 300 cannot be covered on the water inlet 111 in time when hot water flows back is avoided, the risk of water overflow is reduced, and the service life is prolonged. When specifically arranged, the first included angle θ may be 15 °, 16 °, 17 °, 18 °, 19 °, 20 °, 21 °, 22 °, 23 °, 24 °, 25 °. Of course, the first included angle θ is not limited to the above range, and the first included angle θ may have other values within the range of 15 ° to 25 °, and the specific value of the first included angle θ may be determined according to the actual condition of the two-way box 10 of the ironing machine. In other embodiments, the first included angle θ may be out of the range of 15 ° to 25 °, as long as it can achieve the above technical effect.

In one embodiment, the inlet 111 is substantially opposite the outlet 112. For example, the water inlet 111 and the water outlet 112 may be disposed opposite to each other on the side wall 110, which can facilitate the entry of cold water and reduce the backflow of hot water. Of course, the arrangement positions of the water inlet 111 and the water outlet 112 are not limited to this, for example, the water inlet 111 and the water outlet 112 may be arranged on the side wall 110 in a non-opposite way, which enables the structure of the two-way box 10 of the ironing machine to be varied and is suitable for ironing machines 01 with different structural sizes.

In a preferred embodiment, the height of the water inlet 111 is greater than the height of the water outlet 112 in a direction from the side wall 110 toward the top wall 120. In the two-way box 10 of the ironing machine, the height of the water inlet 111 is greater than that of the water outlet 112 by limiting the height of the water inlet 111 along the side wall 110 towards the top wall 120, so that a height difference exists between the water inlet 111 and the water outlet 112, and the cold water flows downwards from the water inlet 111 rapidly, which helps to further facilitate the entry of the cold water. When hot water and/or hot steam enter the box body 100 from the water outlet 112, the backflow difficulty of the hot water and/or the hot steam is increased due to the fall between the water inlet 111 and the water outlet 112, so that the backflow of the hot water can be reduced.

In order to easily cover the swing piece 300 and the water inlet 111, as shown in fig. 6, in an embodiment, the water inlet 111 has a first end surface 113 facing the water outlet 112, and the first end surface 113 forms a second included angle α with the perpendicular direction Y of the box cover 200. Of course, the structure that can cover the flap 300 and the water inlet 111 is not limited to this, and other structure that can meet the requirement may also be used, for example, a wedge block is disposed on a side of the flap 300 facing the water inlet 111, and a surface of the wedge block facing the water inlet 111 is parallel to the first end surface 113 and covers the first end surface 113 (or the water inlet 111) when the flap 300 swings to the water inlet 111 to the maximum extent.

In the two-way box 10 of the ironing machine, the first end surface 113 facing the water outlet 112 of the water inlet 111 and the perpendicular direction Y of the box cover 200 are limited to form a second included angle α, so that the swinging piece 300 can be abutted to the first end surface 113 when swinging towards the water inlet 111 to the maximum extent, and the swinging piece 300 can be conveniently covered on the water inlet 111 to close the water inlet 111. When the box cover is specifically arranged, a second included angle α is formed between the first end surface 113 and the perpendicular direction Y of the box cover 200, and an angle formed between the swing sheet 300 and the perpendicular direction Y of the box cover 200 when the swing sheet 300 swings to the maximum amplitude is the same as the second included angle α, so that the surface of the swing sheet 300 close to the water inlet 111 when the swing sheet 300 swings to the maximum amplitude is parallel to the first end surface 113 and abuts against the first end surface 113.

In order to improve the reliability of the structure, the second angle α may be, in particular, 10 ° to 20 °. Of course, the second included angle α is not limited to the above range, and may be other values within a range that can satisfy the requirement.

In the two-way box 10 of the ironing machine, it is unexpectedly found that the swinging sheet 300 can cover the water inlet 111 in time when hot water flows back by limiting the second included angle alpha to be 10-20 degrees, so as to reduce the risk of water overflow. In a specific arrangement, the second included angle α may be 10 °, 11 °, 12 °, 13 °, 14 °, 15 °, 16 °, 17 °, 18 °, 19 °, 20 °, although the second included angle α is not limited to the above range, and the second included angle α may also be other values within the range of 10 ° to 20 °, and the specific value of the second included angle α may be determined according to the actual conditions of the two-way box 10 of the ironing machine.

In order to limit the swing amplitude of the swing piece 300, in a preferred embodiment, as shown in fig. 6 and 7, a stop rib 240 is disposed on the surface of the box cover 200 facing the bottom wall 130, the stop rib 240 is located on the side of the swing piece 300 close to the water outlet 112, and the stop rib 240 is used for limiting the swing of the swing piece 300. Specifically, the maximum angle of the swing piece 300 swinging towards one side of the water outlet 112 is 10 degrees to 20 degrees, so that the blocking ribs 240 and the swing piece 300 are arranged at intervals, and the swing piece 300 is abutted to the blocking ribs 240 when the swing piece 300 swings for 10 degrees to 20 degrees.

In the two-way box 10 of the ironing machine, the stop rib 240 is arranged on the surface of the box cover 200 facing the side wall 110, and the stop rib 240 is defined on the side of the swing piece 300 close to the water outlet 112 and the swing pieces 300 are arranged at intervals, so as to limit the swing amplitude of the swing piece 300 facing the water outlet 112. The swinging piece 300 is abutted to the blocking rib 240 when the swinging piece 300 swings for 10-20 degrees, so that the swinging piece 300 can be blocked by the blocking rib 240 when swinging for 10-20 degrees, the situation that the swinging of the swinging piece 300 is too large to cover the water inlet 111 in time when hot water flows back due to too large swinging amplitude is avoided, and the safety of the whole structure is improved. And the swing sheet 300 is abutted against the stop rib 240 without swinging to the water outlet 112, so that the swing sheet 300 cannot cover the water outlet 112, and the swing sheet 300 is prevented from blocking the water outlet 112.

In order to ensure the sealing performance of the pendulum plate 300 when covering the water inlet 111, as shown in fig. 5 and 6, in a preferred embodiment, the pendulum plate 300 includes a body 310 and a first sealing member 320, and the first sealing member 320 is disposed on the body 310. The first seal 320 is, for example, a rubber packing.

In one embodiment, the body 310 is provided with at least one first through hole 311, the first through hole 311 penetrates through the body 310 along a thickness direction of the body 310, and the first sealing element 320 is provided with at least one first protrusion 321. The first seal 320 is disposed on the body 310 by fitting the first protrusion 321 in the first through hole 311. In a specific arrangement, the number of the first through holes 311 may be one, two, three, four, or more than four. In another embodiment, a plurality of first through holes 311 are uniformly disposed on the body 310, and the first through holes 311 are through holes penetrating the body 310 in a thickness direction of the body 310. Accordingly, the number of the first protrusions 321 may be one, two, three, four, or more than four, and the positional relationship of the plurality of first protrusions 321 is the same as the positional relationship of the plurality of first through holes 311, so as to embed the first protrusions 321 in the first through holes 311.

In the two-way box 10 of the ironing machine, the swinging sheet 300 is arranged into the body 310 and the first sealing member 320 arranged on the body 310, so that the first sealing member 320 seals the water inlet 111 when the swinging sheet 300 covers the water inlet 111, and the sealing performance of the swinging sheet 300 covering the water inlet 111 is ensured, thereby avoiding the backflow overflow of hot water and improving the working reliability and safety of the ironing machine. In addition, the first through hole 311 is formed in the body 310, the first protrusion 321 is formed in the first sealing member 320, and the first protrusion 321 is embedded in the first through hole 311, so that the first sealing member 320 can be better embedded in the body 310 no matter cold water enters or hot water flows back, and the stability and reliability of the structure of the pendulum piece 300 are improved. In a specific arrangement, the swing sheet 300 may be a structural form of the body 310 and the first sealing element 320 embedded in the body 310, and may also be other structural forms meeting requirements, for example, the swing sheet 300 may include a silicon rubber layer adhered to the body 310, and the specific structure of the swing sheet 300 is determined according to the actual situation of the two-way box 10 of the ironing machine.

The box cover 200 is disposed on the top wall 120, and the box cover 200 covers the first opening 121, and the box cover 200 completely covers the first opening 121. When the swing piece 300 is damaged, the box cover 200 may be fixed on the top wall 120 through a fastening connection, a concave-convex fit, a screw connection, or other detachable connection methods, so as to be conveniently and timely replaced when the swing piece 300 is damaged. For example, as shown in fig. 5 and 6, the box cover 200 is provided with a hook 210, and the top wall 120 is provided with a slot 122 matching with the hook 210.

In another embodiment, a sealant may be further applied between the box cover 200 and the top wall 120 to seal the box cover 200 on the top wall 120 directly by physical connection methods such as adhesive bonding, sealant connection, etc., so as to ensure the overall air tightness and avoid air leakage.
