For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.Embodiment 1

[0036] As shown in FIG. 1 and FIG. 4, the present invention provides a drum washing machine, including a water drum and a ventilation pipe 7 connected to the inside of the water drum, and a heat dissipation structure 8, wherein the air outlet of the ventilation pipe 7 is connected to the outside atmosphere through the heat dissipation structure 8.

[0037] In the embodiment of the present invention, the ventilation pipe 7 is connected to the outside atmosphere via the heat dissipation structure 8, so that the heat dissipation structure 8 can not only dissipate heat and condense the steam generated inside the water drum, and discharge the condensed steam into the outside atmosphere, but also ventilate the water drum with the outside to balance the pressure between the water drum and the outside atmosphere, so that the heat dissipation structure 8 integrates the functions of heat dissipation, condensation and ventilation, thereby simplifying the structure of the drum washing machine.

[0038] Drum washing machine structure 1: the drum washing machine comprises a casing, an outer drum 1 arranged in the casing and an inner drum arranged in the outer drum 1, and the outer drum 1 is a water-containing drum. Drum washing machine structure 2: the drum washing machine comprises a casing and an inner drum arranged in the casing, and the inner drum is a water-containing drum, and the inner drum is a hole-free inner drum.

[0039] For example, when the drying program is executed in the washing machine, steam is generated in the outer drum 1, and the pressure in the outer drum 1 is relatively high. The outer drum 1 is connected to the outside atmosphere through the ventilation pipe 7 and the heat dissipation structure 8, so that the outer drum 1 and the outside atmosphere are ventilated to balance the pressure. At the same time, the heat dissipation structure 8 dissipates heat and condenses the steam generated in the outer drum 1, and the steam is discharged into the outside atmosphere after condensation. The condensed water generated by the heat dissipation and condensation can flow back to the outer drum 1 through the ventilation pipe 7.

[0040] For another example, since there is often an odor in the washing machine after it has not been used for a long time, the outer drum 1 is connected to the outside atmosphere through the ventilation pipe 7 and the heat dissipation structure 8 to achieve ventilation between the outer drum 1 and the outside atmosphere, which can remove the odor inside the outer drum 1.

[0041] As shown in FIG. 3 and FIG. 4, in the embodiment of the present invention, a heat dissipation cavity 83 is formed inside the heat dissipation structure 8. The heat dissipation cavity 83 has an air outlet connected to the outside atmosphere. The air outlet of the ventilation pipe 7 is connected to the inside of the heat dissipation cavity 83.

[0042] In the embodiment of the present invention, the air outlet of the ventilation pipe 7 is connected to the outside atmosphere through the heat dissipation cavity 83. The heat dissipation cavity 83 provides space for the heat dissipation and condensation of steam, delays the discharge of steam, and enables the steam to be fully heat dissipated and condensed in the heat dissipation cavity 83.

[0043] As shown in FIG. 4, a S-shaped heat dissipation channel 831 is provided inside the heat dissipation cavity 83, and the two ends of the heat dissipation channel 831 are respectively provided with an air inlet connected to the ventilation pipe 7 and an air outlet connected to the outside atmosphere. The air outlet of the heat dissipation cavity 83 serves as the air outlet of the heat dissipation channel 831, and the air inlet and air outlet of the heat dissipation channel 831 are respectively arranged on the front and rear sides of the heat dissipation cavity 83.

[0044] The steam enters the S-shaped heat dissipation channel 831 and dissipates heat and condenses in the S-shaped heat dissipation channel 831. The heat dissipation channel 831 is S-shaped, which increases the length of the heat dissipation channel 831, so that the steam stays in the heat dissipation channel 831 for a longer time to dissipate heat and condense, so that the steam can fully dissipate heat and condense. The steam collides and contacts the side walls of the heat dissipation channel 831 with a relatively low temperature, and the heat is dissipated from the heat dissipation channel 831 to the outside of the heat dissipation cavity 83. The condensed water condenses on the side walls of the heat dissipation channel 831, and most of it eventually flows to the bottom wall of the heat dissipation channel 831.

[0045] The front side of the heat dissipation cavity 83 is the side of the washing machine where the outer drum 1 is located. The air inlet and outlet of the heat dissipation channel 831 are respectively arranged on the front and rear sides of the heat dissipation cavity 83 to increase the length of the condensation channel.

The formation of the left main connecting port 832 and the right main connecting port 833 can increase the length of the left main connecting port 832 and the right main connecting port 833 in the up and down directions, avoiding gas congestion and inability to enter the next strip channel.

The hook mouth of the clamping portion 42 is upward, and the front and rear sides are open, the water inlet pipe 3 enters the clamping portion 42 through the hook mouth, and passes through the clamping portion 42 through the open openings on the front and rear sides, so as to be clamped in the clamping space 43.

[0065] As shown in FIG. 9, specifically, the clamping portion 42 includes: a horizontal clamping section 421, which is formed by the first side of the base 41 protruding into the washing machine, and the horizontal clamping section 421 is arc-shaped and protrudes outward from the clamping portion 42.

[0066] A vertical clamping section 422, which is formed by bending the extended end of the horizontal clamping section 421 upward.

[0067] The inclined clamping section 423 is formed by the extended end of the vertical clamping section 422 being bent upward and inclined toward the inside of the clamping portion. The inclined clamping section 423 is arc-shaped and protrudes outward from the clamping portion 42.

[0068] Since the water inlet pipe 3 is a circular water inlet pipe 3, the horizontal clamping section 421 and the inclined clamping section 423 are arc-shaped, which can better fit the outer peripheral wall of the circular water inlet pipe 3, thereby increasing the strength of the clamping space 43 to clamp the water inlet pipe 3.

[0069] The horizontal clamping section 421 has a first arc section, a second arc section and a third arc section. The first arc section serves as a transition section between the right side of the base 41 and the second arc section. The first arc section and the third arc section are symmetrical with the second arc section as the center. The inner side of the horizontal clamping section 421 fits with the arc-shaped outer peripheral wall at the bottom of the circular water inlet pipe 3. The second arc section supports the circular water inlet pipe 3 upward. The first arc section and the third arc section cooperate to clamp the circular water inlet pipe 3 from left to right.

[0070] The vertical clamping section 422 is arranged opposite to the right side of the base 41, and the inner side of the vertical clamping section 422 and the right side of the base 41 are respectively fitted with the vertical outer peripheral walls on the left and right sides of the circular water inlet pipe 3, and the vertical clamping section 422 and the right side of the base 41 cooperate to clamp the circular water inlet pipe 3 on the left and right sides.

[0072] The pipe clamp structure 4 is a plastic part, so that the size of the clamping space 43 formed by the inner side of the clamping portion 42 and the right side of the base 41 can be adjusted, so that the clamping space 43 can clamp the water inlet pipes 3 of different diameters.

[0073] When clamping the water inlet pipe 3, a rightward pulling force is applied to the vertical clamping section 422 or the inclined clamping section 423 of the clamping part 42, so that the clamping space 43 becomes larger, and the water inlet pipe 3 enters the clamping space 43 through the hook mouth of the clamping part 42. After the pulling force is released, the vertical clamping part, the inclined clamping part and the third arc section rebound and abut against the outer peripheral wall of the water inlet pipe 3, thereby clamping the water inlet pipe 3.

[0074] As shown in FIG. 9, more specifically, the clamping portion 42 further includes: The hand-held section 424 is formed by the extended end of the inclined clamping section 423 being bent upward and outward of the clamping portion, and is used to provide a force application location for the external force that changes the size of the clamping space.

Specifically, the locking hole 53 is provided on the left side plate of the washing machine, and the locking portion 44 is locked in the locking hole 53 from right to left.

[0077] As shown in FIG. 8 and FIG. 9, further, the locking portion 44 includes: a locking section 441 is used to lock in the locking hole 53 of the washing machine; a first guiding section 442 is disposed at one end of the locking section 441 away from the interior of the washing machine and gradually tilted from top to bottom toward the exterior of the washing machine for guiding the locking section 441 to enter the locking hole 53.

[0078] The locking section 441 is square, the bottom of the locking section 441 is flat, and the bottom surface of the first guiding section 442 is flush with the bottom surface of the locking section 441.

[0079] When the locking section 441 is locked in the locking hole 53, the first guiding section 442 first guides the locking section 441 into the locking hole 53, and then the locking section 441 is locked with the locking hole 53. The first guiding section 442 improves the accuracy of locking the locking portion 44 with the locking hole 53; the first guiding section 442 is arranged at the left end of the locking section 441.

[0080] As shown in FIG. 8 and FIG. 9, more specifically, the locking portion 44 further includes: a second guiding section 443, which is formed by the bottom of the locking section 441 protruding downward, and a gap is formed between one end of the second guiding section 443 close to the inside of the washing machine and the second side of the base 41, and the second guiding section 443 gradually tilts toward the inside of the washing machine from top to bottom.

[0081] The second guiding section 443 is in a long strip shape, and the second guiding section 443 extends from the middle of the bottom of the locking section 441 to the right side until there is a gap between the second guiding section 443 and the left side of the base 41.

[0082] A clamping groove 444, the clamping groove 444 is formed by the end surface of the second guiding section 443 close to the inside of the washing machine, the bottom of the locking section 441 and the second side of the base 41; the notch of the formed clamping groove 444 is arranged downward.

[0086] The locking portion 44 also includes a limiting section 447. The locking section 441 protrudes upward to form the limiting section 447. The limiting section 447 extends left and right. There are multiple limiting sections 447, and the multiple limiting sections 447 are distributed from front to back. The limiting section 447 can prevent the locking section 441 from moving too far to the left, causing the clamping groove 444 and the vertical locking section 532 to disengage. When the locking section 441 moves to the left and is in place, and the clamping groove 444 and the bottom wall of the vertical locking section 532 are snapped into each other, the left end of the limiting section 447 abuts against the left side wall of the horizontal locking section 531.

[0087] The left section of the limiting section 447 is in an arc shape, which buffers the abutting impact force between the limiting section 447 and the left side wall of the horizontal locking section 531.

[0088] When locking, a leftward thrust is applied to the pipe clamp structure 4, and the first guiding section 442 guides the locking section 441 to enter the horizontal locking section 531. Since the second guiding section is inclined, the left part of the second guiding section passes through the vertical locking section 532, and the right part of the second guiding section does not pass through the vertical locking section 532. The pipe clamp structure 4 continues to be thrusted to the left, so that the right part of the second guiding section passes through the vertical locking section 532, while the clamping groove 444 abuts against the bottom wall of the vertical locking section 532, so that the locking portion 44 is locked in the locking hole 53.
