As shown in fig. 1 to 3, in order to solve the problem that the foam of the existing washing machine is easy to overflow through the water inlet pipeline, the present invention provides a drum washing machine (hereinafter, referred to as washing machine for short), which mainly comprises a machine shell (not shown in the figure), and an outer cylinder 1, an inner cylinder (not shown in the figure) and a detergent box assembly 2 which are arranged in the machine shell, wherein the detergent box assembly 2 is provided with a box outlet pipe 21, the outer cylinder 1 is provided with an outer cylinder pipe 11, and the box outlet pipe 21 is connected with the outer cylinder pipe 11 through a connecting pipe 3 (such as a rubber pipe or a plastic pipe) to achieve the purpose of adding the washing water into the outer cylinder 1 and the inner cylinder. Referring to fig. 3 and 4, a foam overflow preventing unit 4 is further installed between the box-out pipe 21 and the connecting pipe 3, the foam overflow preventing unit 4 includes a housing 41, a water inlet pipe shell 43 connected to the housing 41, a water outlet pipe shell 44, and a moving member 42 disposed in the housing 41, the housing 41 has a water inlet 411 and a water outlet 412, the water inlet pipe shell 43 and the water outlet pipe shell 44 are respectively communicated with the water inlet 411 and the water outlet 412, a diameter-reduced section 4111 is disposed at the water inlet 411, and the moving member 42 can be clamped in the diameter-reduced section 4111 under the action of gravity.

Referring to fig. 3, 4 and 5, in the water inlet stage of the drum washing machine, the washing water enters the detergent box through the water inlet solenoid valve, and enters the outer tub 1 and the inner tub of the washing machine after passing through the box outlet pipe 21, the anti-foam overflow unit 4, the connecting pipe 3 and the outer tub 11 in sequence. When the washing water flows in from the water inlet 411, the movable member 42 is lifted by the washing water to move upwards, so that the water inlet 411 and the water outlet 412 are in a communication state, and the washing water smoothly passes through the foam overflow preventing unit 4; when all the washing water flows out from the water outlet 412, the movable member 42 falls down to the reduced diameter section 4111 under the action of gravity and seals the water inlet 411.

As can be seen from the above description, by providing the foam overflow preventing unit 4 in the box outlet pipe 21 of the drum washing machine, the problems of foam backflow and overflow along the water inlet pipeline generated during the operation of the drum washing machine can be effectively prevented, and the operation safety of the drum washing machine is improved.

It will be understood by those skilled in the art that the drum washing machine obviously includes other parts and structures besides the parts of the washing machine described above, and although not described in the embodiment, the parts should be understood according to the shapes and features of the drum washing machine in the prior art, and the shapes and features should not be construed as limiting the present invention. For example, the drum washing machine may further include a drying system, a damper, a driving motor, a transmission mechanism, and the like.

The foam outflow preventing unit 4 of the present invention will be described in detail with reference to fig. 4 and 5.

As shown in fig. 4 and 5, the left and right sides of the shell 41 of the anti-foam overflow unit 4 are respectively connected with a water outlet pipe shell 44 and a water inlet pipe shell 43, and after connection, a pipe-in-pipe structure is formed. In a preferred embodiment, the water inlet pipe case 43, the water outlet pipe case 44 and the housing 41 are integrally formed, the water inlet pipe case 43 and the water outlet pipe case 44 are tubular structures, and the housing 41 may have a cylindrical structure or a box-type structure. Taking the cylindrical structure as an example, the lower end of the housing 41 is provided with a water inlet 411, and the left end of the housing 41 is provided with a water outlet 412, so that the water inlet direction (i.e. the vertical direction) and the water outlet direction (the horizontal direction) form an included angle of approximately 90 °. The water inlet 411 has a reduced diameter section 4111, the movable member 42 is preferably a ball structure, and an inner ring surface 4112 matching with the surface of the ball structure is disposed on the reduced diameter section 4111, so that the ball structure is embedded in the inner ring surface 4112 under the action of gravity. Wherein, the length of the housing 41 along the outlet direction of the washing water (i.e. the length x indicated in fig. 5) is slightly larger than the diameter of the ball structure, and the diameter of the circle surrounded by the end of the inner ring surface 4112 away from the water inlet 411 (i.e. the diameter d indicated in fig. 5) is smaller than the diameter of the ball structure. In this way, when the ball structure is separated from the inner ring surface 4112, the ball structure can swing left and right along the horizontal direction; when the ball structure is embedded in the inner ring surface 4112, a certain space is formed between the lower half of the ball structure and the reduced diameter section 4111.

With continued reference to fig. 4 and 5, a limiting structure 413, such as a limiting rib extending along the radial direction of the cylindrical housing 41, is further disposed at the water outlet 412 for preventing the ball structure from moving out of the housing 41. The end of the limiting rib extends from the water outlet 412 to the interior of the shell 41 to form a certain guiding inclined plane.

The setting mode has the advantages that: the washing water is jacked up by the washing water when flowing into the water inlet 411 through the ball structure, so that the arrangement mode that the water inlet 411 is communicated with the water outlet 412 can ensure the water inlet fluency and the water inlet efficiency in the water inlet process of the washing machine; through the setting mode that the ball structure seals undergauge section 4111 under the action of gravity behind washing water play delivery port 412, then can realize the complete sealing to the inlet channel after the end of intaking, guarantee that the foam can't follow the inlet channel backward flow and overflow. The interior anchor ring 4112 that sets up on the reducing section 4111 and match with the ball structure plays the effect of direction in the ball structure whereabouts process on the one hand, and on the other hand is more stable when making ball structure embedding interior anchor ring 4112, has increased ball structure embedding interior anchor ring 4112's sealed effect, prevents the excessive effect of foam promptly. The terminal of spacing muscle is by the mode of setting up of delivery port 412 to the inside slope of casing 41, can carry out spacing when the ball structure is jack-up to the ball structure, still is favorable to the installation of ball structure ground, reduces the installation degree of difficulty, only needs gently once to accomplish according to just installing.

In addition, the arrangement mode that the length of the shell 41 in the horizontal direction is larger than the diameter of the ball structure is also beneficial to balancing the pressure in the cylinder. When the door cover of the washing machine is closed, the air pressure inside the inner barrel and the outer barrel 1 is increased instantly, and the increased air pressure can push the ball structure to enable the ball structure to shake left and right in the shell 41, so that the increased air pressure leaks along the water inlet pipeline, and after the air pressure is balanced, the ball structure falls to a sealing state to continue to prevent foam overflow. The diameter of the circle on the upper end of the inner ring surface 4112 is smaller than that of the ball structure, so that a certain space is formed between the lower half part of the ball structure and the reducing section 4111, and the space is formed to facilitate the air pressure to push the ball structure, so that the ball structure is easier to shake.

It should be noted that the above-mentioned embodiments are only used for illustrating the principle of the present invention, and are not intended to limit the protection scope of the present invention, and those skilled in the art can modify the above-mentioned structure so that the present invention can be applied to more specific application scenarios without departing from the principle of the present invention.

For example, in an alternative embodiment, the foam overflow preventing unit 4 may be further disposed between the connection pipe 3 and the outer bobbin 11 in such a manner as to block the foam at the first time when the foam is generated.

For example, in another alternative embodiment, the water inlet pipe shell 43 and the water outlet pipe shell 44 of the anti-foam overflow unit 4 can be omitted, and the corresponding box-out pipe 21 and the corresponding connecting pipe 3 are provided with connecting structures matched with the water inlet 411 and the water outlet 412, so as to realize the installation of the anti-foam overflow unit 4 in the water inlet pipeline.

For example, in an alternative embodiment, the housing 41 may be removably attached, bonded, etc. to the inlet and/or

outlet cartridge

43, 44 to facilitate mounting of the ball structure.

For another example, in another alternative embodiment, the water outlet 412 of the housing 41 may be replaced by a filter screen, a cross-shaped gland, or the like, instead of the limiting rib, which is installed between the water outlet pipe shell 44 and the housing 41.

For another example, in another alternative embodiment, the reduced diameter section 4111 may not have any inner annular surface 4112, or the inner annular surface 4112 may not match with the outer surface of the ball structure, as long as the ball structure falls down to the reduced diameter section 4111 to seal or block the water inlet 411 to effectively prevent foam from overflowing.

For another example, in another alternative embodiment, the included angle between the water inlet 411 and the water outlet 412 may be set to any angle, as long as the angle is set to facilitate the flow of the washing water after the ball structure is jacked up; the number, form and position of the limiting structures 413 are not unique, and a plurality of limiting structures can be arranged, in the form of strip-shaped bulges, on the pipe wall outside the water outlet 412, and the like; the material and form of the ball structure are not exclusive as long as the density of the whole ball structure is less than that of the washing water, for example, the ball structure can also be a hollow ball structure or an oval ball structure, and of course, when the conditions are met, a movable block with a guide inclined surface or a guide conical surface at the lower end or a movable part in other forms can also be used instead.

The operation of the foam-overflow preventing unit 4 will be described with reference to fig. 4 and 5.

Referring to fig. 4 and 5, in one possible embodiment, the water inlet process of the washing machine is as follows: the water source enters the detergent box through the electromagnetic valve and is fused into washing water with the detergent in the detergent box → the washing water enters the water inlet pipe shell 43 through the box outlet pipe 21 and flows to the water inlet 411 of the shell 41 → the ball structure is pushed open by the washing water, so that the water inlet 411 is communicated with the water outlet 412, the washing water passes through the water outlet 412 and sequentially passes through the water outlet pipe shell 44, the connecting pipe 3 and the outer bobbin 11 to enter the outer barrel 1 and the inner barrel → all the washing water flows out of the shell 41, the ball structure falls under the action of gravity and is embedded into the inner annular surface 4112 under the guide of the inner annular surface 4112, and the sealing of the water inlet pipeline is realized.

Finally, it should be noted that although the embodiment is described by taking a drum washing machine as an example, the anti-foam overflow unit of the present invention can be obviously applied to other clothes treating apparatuses as long as the clothes treating apparatus has a water inlet pipeline and can generate foam during operation. For example, the laundry treating apparatus may also be a pulsator washing machine, a shoe washing machine, a dish washing machine, or the like.
