[0052] In some embodiments, referring to FIG. 3, the outer drum 2 further includes a second chamber 22 (an outer drum chamber), the second chamber 22 is defined in the first body, and the second chamber 22 communicates with the first opening 21, the second chamber 22 can hold water, and the inner drum 3 is arranged in the second chamber 22.

[0053] In some embodiments, referring to FIG. 3, the inner drum 3 includes a fourth opening 31 (an inner drum opening), and the fourth opening 31 is formed at a front end of a second body.

[0054] It should be noted that the front end of the second body is an end of the inner drum 3 close to the fourth opening 31.

[0055] In some embodiments, referring to FIG. 3, the inner drum 3 further includes a third chamber 32 (a washing chamber), the third chamber 32 communicates with the second chamber 22, the third chamber 32 communicates with the fourth opening 31, and the third chamber 32 also communicates with the third opening 111.

[0056] In some embodiments, referring to FIG. 3, the inner drum 3 further includes a fourth plate 33 (an inner drum side peripheral wall), and the fourth plate 33 is provided with a water permeable hole penetrating through the fourth plate, and water can enter and exit the third chamber 32 through the water permeable hole.

[0057] For example, the user can place laundry to be washed into the inner drum 3 through the third opening 111, the first opening 21 and the fourth opening 31.

[0058] In some embodiments, referring to FIG. 1, the laundry treatment apparatus 100 further includes a door 42, and the door 42 is rotatably connected to the cabinet and configured to open or close the third chamber 32.

[0059] For example, the door 42 is rotatably connected to the third plate 11; when the door 42 rotates in a direction away from the third plate 11, the third opening 111 is opened, and laundry can be placed through the third opening 111; and when the door 42 rotates in a direction toward the third plate 11, the third opening 111 is closed.

[0060] In some embodiments, referring to FIG. 1 to FIG. 3, the laundry treatment apparatus 100 further includes a door seal 41, the door seal 41 is located between the third opening 111 and the first opening 21, and the door seal 41 is configured to seal a gap between the third opening 111 and the first opening 21, thereby preventing washing water in the outer drum 2 from flowing out of the outer drum 2 through a gap between the cabinet and the outer drum 2 and entering the cabinet 1.

[0061] In some embodiments, referring to FIG. 4 to FIG. 6, the outer drum 2 further includes a first plate 23 (an outer drum rear wall), and the first plate 23 is arranged at a rear end of the first body away from the first opening 21.

[0062] In some embodiments, referring to FIG. 4-6, the laundry treatment apparatus 100 further includes a first channel 51 (a drying air duct), and the first channel 51 is formed outside the outer drum 2. The first plate 23 includes a second opening 231 (an air return port). A first end of the first channel 51 communicates with the second opening 231, and a second end of the first channel communicates with the third chamber 32.

[0063] In some embodiments, the first end of the first channel 51 passes through the door seal 41 and communicates with the third chamber 32. For example, air in the first channel 51 passes through the door seal 41 and the fourth opening 31, and enters the inner drum 3.

[0064] In some embodiments, the laundry treatment apparatus 100 further includes a drying device. The drying device is arranged in the first channel 51, and the drying device is configured to dry hot and humid air entering the first channel 51.

[0065] During drying, the air in the inner drum 3 exchanges heat with the laundry to form hot and humid air, and the second opening 231 is configured to enable the hot and humid air in the third chamber 32 to flow into the first channel 51. That is, the hot and humid air enters the outer drum 2 and then enters the first channel 51 through the second opening 231, the hot and humid air is dried in the first channel 51 to form dry air, and the dry air flows into the third chamber 32 through the second end of the first channel 51 so as to exchange heat with the laundry to dry the laundry.

[0066] In some embodiments, the hot and humid air is dried through the first channel 51 and the drying effect is poor. Therefore, a condenser can be arranged on a rear side of the first plate 23, so that as the hot and humid air can be condensed before entering the first channel 51 or when entering the first channel 51, thereby reducing the temperature and humidity of the hot and humid air. However, in related art, the condenser is generally arranged on a rear side of the first plate 23, thereby affecting the heat exchange efficiency between the condenser and the hot and humid air. Since the dehumidification effect of the condenser on the hot and humid air is reduced, the hot and humid air is difficult to dry, and the laundry drying time is prolonged. Furthermore, after long-term operation, a small amount of lint that cannot be flushed away in the third chamber 32 is subjected to repeated spraying, wetting and drying, resulting in a large amount of lint in the third chamber 32. During air circulation, the air easily carries the lint into the first channel 51, so that the lint is attached to an inner surface of the first channel 51 and a surface of the drying device. After long-term accumulation, the smoothness of the first channel 51 and the heat exchange between the drying device and the air will be affected, leading to longer drying time.

[0067] To solve the above problems, some embodiments of the present disclosure provide a laundry treatment apparatus 100. Hot and humid air generated from laundry in a third chamber 32 of an inner drum 3 enters an outer drum 2, the hot and humid air flows from one side of a condensing plate close to a first opening 21 to the condensing plate, the hot and humid air exchanges heat with the condensing plate to condense moisture in the hot and humid air, the hot and humid air passes through a filtering portion 5211 and a first hole 5212 (an air passage hole) and flows to a second opening 231, the hot and humid air passing through the second opening 231 enters the first channel 51, and the filtering portion 5211 filters out lint from the hot and humid air flowing through a shielding region 521.

[0068] Referring to FIG. 7, the condensing plate 52 is arranged in a second chamber 22, so that the condensing plate 52 can condense water from the hot and humid air, thereby achieving a pre-dehumidification effect on the hot and humid air, reducing the burden on the drying device in the first channel 51, improving the dryness of the hot and humid air after drying, and shortening the drying time for the laundry.

[0069] Furthermore, the filtering portion 5211 is arranged at the shielding region 521 of the condensing plate 52, so that lint in the air can be filtered out, thereby preventing the lint from entering the first channel 51, ensuring the heat exchange efficiency in the first channel 51 and shortening the drying time; and a first hole 5212 (an air passage hole) is formed at the shielding region 521, thereby ensuring a return air volume and the drying efficiency.

[0070] In some embodiments, referring to FIG. 7, the laundry treatment apparatus 100 further includes a condensing plate 52, the condensing plate 52 is arranged in the second chamber 22, the condensing plate 52 is connected to one side of the first plate 23 close to the third plate 11 (such as a front side of the first plate 23), and the condensing plate 52 is configured to exchange heat with the hot and humid air, so that the moisture in the hot and humid air is condensed.

[0071] In some embodiments, referring to FIG. 7, the condensing plate 52 includes a shielding region 521, and the shielding region 521 is configured to shield the second opening 231.

[0072] It should be noted that the second opening 231 is formed in an upper part of the first plate 23. The setting position of the shielding region 521 is adapted to the setting position of the second opening 231.

[0073] In some embodiments, referring to FIG. 3 and FIG. 7, the shielding region 521 includes a filtering portion 5211. The filtering portion 5211 communicates the second opening 231 with an accommodation space of one side of the condensing plate 52 close to the first opening 21, and the filtering portion 5211 is configured to filter lint from the hot and humid air flowing through the filtering portion 5211.

[0074] In some embodiments, referring to FIG. 3 and FIG. 7, the shielding region 521 further includes a first hole 5212, and the first hole 5212 also communicates the second opening 231 with the accommodation space of one side of the condensing plate close to the first opening 21. In this way, the hot and humid air after heat exchange can flow into the first channel 51 through the first hole 5212.

[0075] In some embodiments, referring to FIG. 12, the filtering portion 5211 includes at least one second hole 52111 (a filtering hole). In this way, the second hole 52111 facilitates the filtration of the lint in the hot and humid air flowing through the filtering portion 5211.

[0076] For example, a length direction of any second hole 52111 of the at least one second hole 52111 is parallel to a height direction of the cabinet 1.

[0077] In some embodiments, when the length of the second hole 52111 is less than 15 mm, the number of the second holes 52111 formed in the condensing plate 52 will be increased; and as the length of the second hole 52111 decreases, the production cost is increased.

[0078] In some embodiments, when the length of the second hole 52111 is greater than or equal to 15 mm, for example, the length of the second hole 52111 is 15 mm, 20 mm or 25 mm, the number of the second holes 52111 formed in the condensing plate 52 can be reduced, thereby reducing the manufacturing cost of the condensing plate 52 on the premise of ensuring the filtering effect.

[0079] In some embodiments, when the length of the second hole 52111 is greater than 30 mm, the structural strength of the condensing plate 52 will be reduced; and as the length of the second hole 52111 increases, the service life of the condensing plate 52 will be affected.

[0080] In some embodiments, when the length of the second hole 52111 is less than or equal to 30 mm, for example, the length of the second hole 52111 is 20 mm, 25 mm or 30 mm, the structural strength of the condensing plate 52 can be enhanced, thereby prolonging the service life of the condensing plate 52.

[0081] In some embodiments, when the length of the second hole 52111 is greater than equal to 15 mm, and the length of the second hole 52111 is less than or equal to 30 mm, for example, the length of the second hole 52111 is 15 mm, 20 mm, 25 mm or 30 mm, the production of the condensing plate 52 can be reduced, the structural strength of the condensing plate 52 can be enhanced, and the service life of the condensing plate 52 can be prolonged.

[0082] In some embodiments, when the width of the second hole 52111 is less than 3 mm, lint in the air may clog the second hole 52111; and as the width of the second hole decreases, the return air volume will be reduced, thereby prolonging the drying time.

[0083] In some embodiments, when the width of the second hole 52111 is greater than or equal to 3 mm, for example, the width of the second hole 52111 is 3 mm, 4 mm or 5 mm, the width of the second hole 52111 formed in the condensing plate 52 can be increased, thereby increasing the return air volume and improving the drying efficiency.

[0084] In some embodiments, when the width of the second hole 52111 is greater than 7 mm, as the width of the second hole 52111 increases, lint in the air may flow into the first channel 51, so that the lint is attached to the inner surface of the first channel 51, thereby affecting the heat exchange effect.

[0085] In some embodiments, when the width of the second hole 52111 is less than or equal to 7 mm, for example, the width of the second hole 52111 is 5 mm, 6 mm or 7 mm, the lint in the air can be prevented from entering the first channel 51.

[0086] In some embodiments, when the width of the second hole 52111 is greater than or equal to 3 mm and the width of the second hole 52111 is less than or equal to 7 mm, for example, the width of the second hole 52111 is 4 mm, 5 mm or 6 mm, the lint in the air can be prevented from entering the first channel 51, the return air volume is increased, and the drying efficiency is improved.

[0087] In some embodiments, referring to FIG. 8, the second hole 52111 includes a first section 521111 (an upper section of the filtering hole), and in the height direction of the cabinet 1, the first section 521111 is located above the filtering portion 5211.

[0088] The second hole 52111 further includes a second section 521112 (a middle section of the filtering hole), and in the height direction of the cabinet 1, the second section 521112 is located below the first section 521111.

[0089] The second hole 52111 further includes a third section 521113 (a lower section of the filtering hole), and in the height direction of the cabinet 1, the third section 521113 is located below the second section 521112.

[0090] For example, the second section 521112 is located between the first section 521111 and the third section 521113.

[0091] It should be noted that a longitudinal cross-section of the first section 521111 is semicircular, a longitudinal cross-section of the second section 521112 is rectangular, and a longitudinal cross-section of the third section 521113 is semicircular. Here, the longitudinal cross-section refers to a cross-section in the front-rear direction of the cabinet 1.

[0092] In some embodiments, when the second hole 52111 includes the second section 521112, the width of the second section 521112 is greater than or equal to 3 mm and less than or equal to 7 mm. It should be noted that the width of the second section 521112 is substantially the same as the width of the second hole 52111, and the setting principle of the width of the second section 521112 is similar to that of the second hole 52111, which will not be described in detail here. For example, the width of the second section 521112 may be 5 mm.

[0093] In some embodiments, in the case where the at least one second hole 52111 includes a plurality of second holes 52111, the plurality of second holes 52111 are arranged in at least one row, and each row of second holes 52111 are arranged along an extension direction of the arc of the condensing plate 52.

[0094] It should be noted that the extension direction of the arc refers to a circumferential direction of the condensing plate 52.

[0095] For example, when the second holes 52111 are arranged in a plurality of rows, arcs along which any two rows of the plurality of rows of second holes 52111 are arranged are arcs with the same center.

[0096] It should be noted that the center of the arc along which the second holes 52111 are arranged is located on a rotating shaft of the inner drum 3.

[0097] In some embodiments, referring to FIG. 7 and FIG. 8, taking a plane perpendicular to the axial direction of the outer drum 2 as a reference plane, the area of the orthographic projection of the first plate 23 on the reference plane is M1, the area of the orthographic projection of the condensing plate 52 on the reference plane is M2, and the area of the orthographic projection on the reference plane is M2.

[0098] It should be noted that M1 is greater than M2, thereby facilitating the arrangement of the condensing plate 52 in the second chamber 22.

[0099] In some embodiments, M1 and M2 satisfy the following relational expression: M2 / M1>1 / 4.

[0100] In some embodiments, when M2 / M1<1 / 4, the condensing plate 52 is too small; and as M2 / M1 decreases, the condensation performance is poor and the drying time is prolonged.

[0101] In some embodiments, when M2 / M1>1 / 4, the area of the condensing plate 52 is increased, thereby preventing the condensing plate 52 from being too small and resulting in poor condensation performance; and as M2 / M1 increases, the pre-dehumidification effect can be improved, the burden on the drying device in the first channel 51 can be reduced, the drying degree of the hot and humid air after drying can be increased, and the drying time for the laundry can be shortened.

[0106] In some embodiments, when 1 / 4<M4 / M3, for example, M4 / M3 is 1 / 4, 2 / 4 or 3 / 4, it is beneficial for the air to flow into the first channel 51, thereby improving the drying efficiency.

[0107] In some embodiments, when 1 / 4<M4 / M3 < 1, for example, M4 / M3 is 1 / 4, 2 / 4 or 3 / 4, the second hole 52111 can block some lint, thereby reducing the lint flowing into the first channel 51 through the first hole 5212, reducing the return air resistance, ensuring the return air volume, and ensuring the drying efficiency.

[0233] It should be noted that, in the axial direction of the outer drum 2, L3 is positively correlated with a length of the outer drum 2. For example, as the length of the outer drum changes, L3 will also change accordingly.

[0234] In some embodiments, in a radial direction of the outer drum 2, a distance from the third sub-plate 2413 to the inner drum 3 is L4.

[0235] In some embodiments, when L4<20 mm, due to the short distance from the third subplate 2413 to the inner drum 3, the insufficient water is in the second chamber 22, thereby affecting the steaming and ironing function.

[0236] In some embodiments, when L4>20 mm, for example, when L4 is 20 mm or 30 mm, as L4 increases, it is beneficial for improving the steaming and ironing function of the fifth chamber 241.

[0237] In some embodiments, when L4>50 mm, due to the small distance from the third subplate 2413 to the inner drum 3 means that, in a radial direction of the inner drum 3, a distance from the outer drum 2 to the inner drum 3 is large, resulting in excessive water in the second chamber 22, thereby wasting water.

[0238] In some embodiments, when L4<50 mm, for example, when L4 is 40 mm or 50 mm, the distance from the outer drum 2 to the inner drum 3 is reduced; and as the value of L4 decreases, it is beneficial for reducing water in the second chamber 22 and avoiding water waste.

[0240] In some embodiments, referring to FIG. 28, a length of the fifth chamber 241 in a front-rear direction of the laundry treatment apparatus 100 is D1.

[0241] In some embodiments, when D1<200 mm, due to the short length of the fifth chamber 241, the heating portion 581 in the fifth chamber 241 will be small, resulting in a poor heating effect, thereby affecting the steaming and ironing function.

[0242] In some embodiments, when D1>200 mm, for example, when D1 is 200 mm or 225 mm, the heating portion 581 in the fifth chamber 241 is large; and as the value of D1 increases, the heating effect in the fifth chamber 241 is good, thereby improving the steaming and ironing function.

[0243] In some embodiments, when D1>250 mm, the excessive length of the fifth chamber 241 leads to a large volume of the fifth chamber 241, thereby wasting water.

[0244] In some embodiments, when D1<250 mm, for example, when D1 is 225 mm or 250 mm, it is beneficial for reducing the volume of the fifth chamber 241; and as the value of D1 decreases, it is beneficial for avoiding water waste.
