[0044] The preferred embodiments of the present application will be described below with reference to the drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present application, and are not intended to limit the protection scope of the present application.

[0045] It should be noted that in the description of the present application, the terms "horizontal", "vertical", "left", "right" and other terms indicating direction or positional relationship are based on the direction or positional relationship shown in the drawings, which is only for the convenience of description, and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present application.

[0046] In addition, it should also be noted that in the description of the present application, unless otherwise explicitly specified and limited, the terms "providing", "connecting", "installing" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrally connected. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0047] Specifically, the present application provides a clothes treatment apparatus, such as Figure 1 As shown in the drawings, the clothes treatment apparatus of the present application comprises a cabinet 1 and a drum 2 installed in the cabinet 1, and the drum 2 can rotate relative to the cabinet 1.

[0048] Among them, the clothes treatment apparatus of the present application can be a drum washing machine, which comprises an outer drum and an inner drum rotatably arranged in the outer drum, and the rear end of the outer drum is provided with a driving device for driving the inner drum to rotate. The drum 2 is the inner drum.

[0049] The clothes treatment apparatus of the present application can also be a clothes dryer, and the drum 2 is a drying drum. The clothes treatment apparatus of the present application can also be a washer-dryer. Whether it is a clothes dryer or a washer-dryer, a drying device is also installed in the cabinet 1, and the drying device can extract the wet air in the drum 2 and send it back to the drum 2 after dehumidification and heating. By making the air flow circulate between the drum 2 and the drying device, the clothes in the drum 2 can be dried.

[0050] For example, the drying device includes a heat pump module, a drying fan 32, and a drying duct 31. The two ends of the drying duct 31 are connected to the front end and the rear end of the drum 2, respectively. The evaporator 33 and the condenser 34 of the heat pump module are both installed in the drying duct 31. The evaporator 33 is located upstream of the condenser 34. The evaporator 33 is used to dehumidify the humid air, and the condenser 34 is used to heat the airflow. The drying fan 32 is also installed in the drying duct 31 so that the airflow can circulate between the drum 2 and the drying duct 31.

[0051] It should be noted that those skilled in the art can also use other types of dehumidification components and heating components to replace the evaporator 33 and condenser 34 described above in practical applications. Such flexible adjustments and changes do not deviate from the principles and scope of this utility model and should be limited to the protection scope of this utility model.

[0052] Furthermore, it should be noted that, in practical applications, those skilled in the art can position the air inlet of the drying device closer to the front end of the drum 2 and the air outlet of the drying device closer to the rear end of the drum 2. During the drying process, the humid air inside the drum 2 is discharged from the front end of the drum 2 and enters the drying device. After being dehumidified and heated by the drying device, it re-enters the drum 2 from the rear end. Alternatively, the air inlet of the drying device can be positioned closer to the rear end of the drum 2 and the air outlet of the drying device closer to the front end of the drum 2. During the drying process, the humid air inside the drum 2 is discharged from the rear end of the drum 2 and enters the drying device. After being dehumidified and heated by the drying device, it re-enters the drum 2 from the front end. Such flexible adjustments and changes do not deviate from the principle and scope of this utility model and should be limited to the protection scope of this utility model.

[0053] Preferably, such as Figure 1 As shown, the air inlet of the drying device of this utility model is located below the opening of the drum 2, and the air outlet of the drying device is connected to the rear end of the drum 2.

[0054] For example, such as Figure 1 As shown, the drying device is located below the drum 2, and the drying air duct 31 extends from the front end of the drum 2 (from... Figure 1 (Viewed from above, left end) extends to the rear end of roller 2 (from...) Figure 1 (Viewed from the top, right end) When the drying program is executed, the drying fan 32 is started, and the humid air in the drum 2 is discharged from the drum opening and enters the drying air duct 31. Then it flows along the drying air duct 31 toward the rear end of the drum 2. After dehumidification and heating, it enters the drum 2 from the rear end to dry the clothes in the drum 2.

[0055] Preferably, such as Figure 1As shown, the clothes treatment equipment further comprises a lint collecting box 4 installed at the barrel opening of the drum 2, and the airflow discharged from the barrel opening first flows through the lint collecting box 4 and then enters the drying device.

[0056] The lint collecting box 4 can filter and collect the lint and other impurities carried by the airflow, and prevent the impurities from entering the drying air duct 31.

[0057] Preferably, as shown, Figure 1 As shown, the clothes treatment equipment further comprises a lint collecting box 4 installed at the barrel opening of the drum 2, and the airflow discharged from the barrel opening first flows through the lint collecting box 4 and then enters the drying device.

[0058] During the execution of the drying program, the air is blown towards the inner bottom of the drum 2 by the air supply device, so that the wind directly blows on the clothes located at the bottom of the drum 2, which is beneficial to improve the heat and moisture exchange efficiency between the clothes and the drying airflow, thereby improving the drying efficiency of the clothes treatment equipment, speeding up the drying speed, and reducing the rotation speed of the drum 2. In some cases (for example, in the case of less clothes), the drum 2 can even not be rotated, which greatly reduces the mechanical wear of the clothes. In addition, since the air supply device is installed in front of the drum 2, the air can be directly blown into the drum 2 through the barrel opening of the drum 2, and the wind power is stronger, so that the air supply device can provide strong wind to impact the clothes in the drum 2, which is beneficial to make the clothes more fluffy, and the user wears more comfortable. In addition, strong wind is also beneficial to strip the dust, hair and other impurities on the clothes.

[0059] Preferably, as shown, Figure 1 As shown, the clothes treatment equipment further comprises a lint collecting box 4 installed at the barrel opening of the drum 2, and the airflow discharged from the barrel opening first flows through the lint collecting box 4 and then enters the drying device.

[0060] That is, in addition to the circulation airflow formed between the drying device and the drum 2, a circulation airflow can also be formed between the air supply device and the drum 2, and the two circulation airflows are mixed with each other, which can further improve the drying efficiency.

[0061] It should be noted that in the case where the drying device and the lint collecting box 4 are provided, the airflow discharged from the barrel opening of the drum 2 is preferably first flowed through the lint collecting box 4, and then divided into two airflows which respectively enter the drying device and the air supply device. If there is no drying device, only the lint collecting box 4, the airflow filtered by the lint collecting box 4 only flows into the air supply device.

[0062] In addition, it should be noted that the lint collecting box 4 and the air supply device can be arranged in the washing machine cabinet 1 as well as the clothes dryer and the washer-dryer, and are both installed at the drum opening of the drum 2. In this case, the air blown by the air supply device flows towards the rear end of the drum 2 first after entering the drum 2, and then flows towards the front end of the drum 2 after turning back. The air flows through the lint collecting box 4 before being discharged from the drum opening at the front end of the drum 2 and then enters the air supply device.

[0063] Through the above arrangement, the washing machine has the dust and hair removing function in addition to the washing function. Specifically, when the clothes of the user have dust or a large amount of hair (such as cat hair), but the user does not want to wash the clothes, the clothes can be placed in the inner drum of the washing machine, and then the air supply device is turned on to supply air to the inner drum. When the strong wind blows on the clothes, the dust and hair on the clothes can be removed. The air flow is filtered and collected by the lint collecting box 4 when flowing through the lint collecting box 4, so that the dust and hair on the clothes are stripped.

[0064] It should be noted that in addition to the washing machine, the lint collecting box 4 and the air supply device can also be arranged in the clothes dryer and the washer-dryer. In this case, the lint collecting box 4 and the air supply device can be used to remove the dust and hair on the clothes without turning on the drying device.

[0065] Preferably, as shown in Figure 4 The lint collecting box 4 of the utility model comprises a first filter screen frame 41, a second filter screen frame 42, a first filter screen (not shown in the figure) arranged on the first filter screen frame 41, a second filter screen (not shown in the figure) arranged on the second filter screen frame 42, and a top cover 43. The first filter screen frame 41 and the second filter screen frame 42 are arranged in a V shape. The bottom end of the first filter screen frame 41 is connected with the bottom end of the second filter screen frame 42, preferably by pivoting connection. The top end of the first filter screen frame 41 and the top end of the second filter screen frame 42 are both connected with the top cover 43. The top cover 43 is provided with a plurality of air inlet holes 431.

[0066] The air flow discharged from the drum opening of the drum 2 enters the lint collecting box 4 through the air inlet holes 431 on the top cover 43, and is then discharged after being filtered by the first filter screen and the second filter screen. The filtered lint and other impurities are collected in the cavity between the first filter screen and the second filter screen.

[0067] Preferably, as shown in Figures 1 to 3 The air supply device of the utility model blows air downward.

[0068] The air outlet of the air supply device is higher than the barrel opening of the drum 2, the air blown from the air supply device flows obliquely downward to the inner bottom of the drum 2, is refracted to flow obliquely upward toward the rear end of the drum 2, and then is refracted again to flow toward the front end of the drum 2 through the rear wall of the drum 2, that is, by making the air supply device blow air obliquely downward, the air circulation between the drum 2 and the air supply device is more favorable.

[0069] Preferably, as shown in Figure 3 the extension line of the air outlet direction of the air supply device intersects the inner bottom of the drum 2 at a position that is 1 / 4 to 3 / 4 of the axis length of the drum 2 from the axis of the barrel opening of the drum 2.

[0070] That is, the air blown from the air supply device preferably falls on the drum 2 at 1 / 4 to 3 / 4, that is, the region between the point a and the point c in Figure 3 , so that the air circulation between the drum 2 and the air supply device is more favorable. Most preferably, the air blown from the air supply device falls on the drum 2 at the middle position, that is, at 1 / 2 of the drum 2, that is, around the point b in Figure 3 .

[0071] It should be noted that in addition to the above-mentioned manner of limiting the air outlet direction of the air supply device, the air outlet direction of the air supply device can also be limited by the included angle with the axis direction of the drum 2, and preferably the extension line of the air outlet direction of the air supply device intersects the axis direction of the drum 2 at an angle of 45 degrees to 85 degrees.

[0072] Exemplarily, the extension line of the air outlet direction of the air supply device intersects the axis direction of the drum 2 at an angle of 45 degrees, 50 degrees, 55 degrees, 60 degrees, 65 degrees, 70 degrees, 75 degrees, 80 degrees, or 85 degrees.

[0073] Preferably, as shown in Figures 1 to 3 , the air supply device of the utility model comprises a fixing member 6 and a fan 5, the fan 5 is installed on the fixing member 6 and located in front of the drum 2, and the air outlet of the fan 5 faces the inner bottom of the drum 2.

[0074] That is, the clothes treatment device of the utility model is equivalent to being provided with double fans, one of which is a drying fan 32 of a drying device, and the drying fan 32 is installed in a drying air duct 31, and the main function of the drying fan 32 is to deliver hot air into the drum 2, and the other is a fan 5 directly installed at the front end of the drum 2, and the main function of the fan 5 is to deliver strong air into the drum 2 to generate a strong cyclone, which can float the clothes in the drum 2 and accelerate the drying of the clothes, and is beneficial to reducing the damage of friction to the clothes.

[0075] Exemplarily, the fixing member 6 is fixedly connected with the cabinet 1 and located between the drum 2 and the front panel of the cabinet 1, and the fan 5 is fixedly installed on the fixing member 6. The lint collecting box 4 can also be installed on the fixing member 6.

[0076] It should be noted that the fixing member 6 can be cancelled in actual application by those skilled in the art, in which case, the fan 5 can be installed on the front panel of the cabinet 1, or on the door body, or on the window cushion between the door body and the drum 2, and the like, and the adjustment and change of the specific installation position of the fan 5 do not deviate from the principles and scope of the present application, and should be limited within the protection scope of the present application.

[0077] Preferably, as shown in Figure 3 and Figure 5 , the fixing member 6 is provided with a containing cavity and an air outlet 61 communicating with the containing cavity, and the fan 5 is fixedly installed in the containing cavity, and the air outlet of the fan 5 faces the air outlet 61 on the fixing member 6.

[0078] After the airflow in the drum 2 is discharged from the drum opening, it first flows through the lint collecting box 4 at the drum opening, is filtered by the lint collecting box 4, and is then sucked into the fan 5, and the airflow discharged from the air outlet of the fan 5 blows towards the inner bottom of the drum 2 through the air outlet 61 on the fixing member 6, wherein the air outlet of the fan 5 is inclined downward.

[0079] It should be noted that the shape of the air outlet 61 is not limited in the present application, for example, the air outlet 61 can be circular, square or offset nozzle-shaped, and the like, and the adjustment and change of the specific shape of the air outlet 61 do not deviate from the principles and scope of the present application, and should be limited within the protection scope of the present application.

[0080] Preferably, as shown in Figure 5 , the fixing member 6 is provided with a blocking rib 62 in the air outlet 61 to prevent the clothes in the drum 2 from entering the air outlet 61.

[0081] By providing the blocking rib 62 in the air outlet 61 of the fixing member 6, it can prevent the clothes from entering the air outlet 61, and can more effectively prevent the clothes from entering the fan 5 through the air outlet 61.

[0082] Preferably, as shown in Figure 5 , the number of the blocking ribs 62 is multiple, and the multiple blocking ribs 62 are distributed along the radial direction of the air outlet 61.

[0083] For example, the air outlet 61 is circular, and there are three baffles 62, which are horizontally arranged and spaced apart along the diameter of the air outlet 61. Furthermore, a vertical baffle 62 is provided in the middle of the three baffles 62, which intersects the three horizontal baffles 62 perpendicularly.

[0084] It should be noted that, in practical applications, those skilled in the art can make the retaining rib 62 integrally set with the fixing member 6, or connect it to the fixing member 6 by plugging or snapping, etc. Such adjustments and changes to the specific connection method between the retaining rib 62 and the fixing member 6 do not deviate from the principle and scope of this utility model, and should all be limited to the protection scope of this utility model.

[0085] Preferably, the air supply device of this utility model further includes a filter screen (not shown in the figure), which is installed at the air inlet of the fan 5 to prevent lint from entering the fan 5.

[0086] By installing a filter screen at the air intake of the fan 5, lint can be prevented from entering the fan 5. Especially when a lint collection box 4 is installed, the airflow is filtered twice before entering the fan 5, resulting in a better filtration effect.

[0087] Preferably, such as Figures 6 to 11 As shown, the air supply device of this utility model also includes a damper assembly, which is used to shield the exhaust port of the fan 5.

[0088] When the air supply device is not required to operate, the exhaust port of the fan 5 can be blocked by the damper assembly to prevent water inside the drum 2 from splashing into the outer casing of the fan 5. In addition, during the operation of the drying device, the drying airflow can be prevented from entering the outer casing of the fan 5 from the exhaust port, thereby preventing impurities such as lint from entering the fan 5.

[0089] It should be noted that, in practical applications, those skilled in the art can configure the damper assembly as a wind-driven damper, that is, the damper assembly opens by the air blown out from the exhaust port of the fan 5. Alternatively, the damper assembly can be configured as an electric damper, that is, the damper is opened by a motor. Such adjustments and changes to the specific type of damper assembly do not deviate from the principle and scope of this utility model and should be limited to the protection scope of this utility model.

[0090] Preferably, such as Figures 6 to 11 As shown, the damper assembly of this utility model includes an annular fixing plate 71 and a damper 72, with the damper 72 pivotally connected to the fixing plate 71.

[0091] For example, the fixing plate 71 is fixedly connected to the housing of the fan 5, and the through hole in the middle area of ​​the fixing plate 71 is aligned with the exhaust port of the fan 5. The shape and size of the through hole match the shape and size of the exhaust port of the fan 5.

[0092] It should be noted that the skilled person in the actual application can also fixedly connect or integrally set the fixed plate 71 with the fixed member 6 on which the fan 5 is installed, or can also cancel the fixed plate 71 and directly pivotally connect the air door 72 with the shell of the fan 5, and the like, and such flexible adjustment and change do not deviate from the principles and scope of the present application, and should be limited within the protection scope of the present application.

[0093] In addition, it should be pointed out that, as shown in Figure 6 , if an electric air door is used, a motor 73 needs to be installed on the fixed plate 71 to drive the air door 72 to open, as shown in Figure 7 , if a wind-driven air door is used, the motor 73 can not be set, and the air blown out of the air outlet of the fan 5 will open the air door 72.

[0094] Preferably, as shown in Figures 6 to 9 , the number of air doors 72 is multiple, the multiple air doors 72 are independent, and the multiple air doors 72 collectively shield the air outlet of the fan 5.

[0095] When the air door 72 is in a closed state, as shown in Figure 9 , it is preferred that there is an overlapping part between the two adjacent air doors 72, so that the air outlet of the fan 5 can be better shielded.

[0096] It should be noted that if the air door 72 is electric, as shown in Figure 6 , it is preferred that one motor 73 is configured for each air door 72, and each air door 72 can be independently opened by the motor 73. Exemplarily, the number of air doors 72 is four, and the number of motors 73 is also four, and the four motors 73 independently drive the four air doors 72, respectively.

[0097] Preferably, as shown in Figures 6 to 11 , a limiting structure is arranged on the air door 72, and the limiting structure abuts against the fixed plate 71 after the air door 72 is opened to limit the air door 72 at a set open position.

[0098] By limiting the air door 72 at the set open position through the limiting structure, the opening angle of the air door 72 can be limited, so that the air flow discharged from the air outlet of the fan 5 is not excessively diffused due to the excessively large opening angle of the air door 72, and in addition, for the wind-driven air door, by limiting the air door 72 at the set open position through the limiting structure, the situation that the air door 72 cannot be closed due to the excessively large opening angle can be avoided.

[0099] Preferably, as shown in Figure 8As shown, the plurality of dampers 72 are parallel to each other when in the set open position, and a guide air passage is formed between two adjacent dampers 72, the guide air passage is directed towards the air outlet 61, i.e. towards the inner bottom of the drum 2.

[0100] After the dampers 72 are opened, each damper 72 is limited in the set open position by the respective limiting structure, and a guide air passage is formed between two adjacent dampers 72, the airflow discharged from the air outlet of the air blower 5 flows along the guide air passage to the air outlet 61 on the fixed member 6, and then flows to the inner bottom of the drum 2 through the air outlet 61, which can more effectively prevent the airflow from escaping and make the wind force stronger.

[0101] Preferably, as shown in the drawings, Figures 6 to 11 The damper 72 comprises a plate-shaped body 721 and a rotating shaft 722 arranged on the plate-shaped body 721, the rotating shaft 722 is pivotally connected with the fixed plate 71, and the limiting structure is arranged on the rotating shaft 722.

[0102] For example, a plurality of clamping grooves 711 are arranged on the fixed plate 71, and each of the two sides of the plate-shaped body 721 of the damper 72 has a rotating shaft 722, each rotating shaft 722 is rotatably connected with a corresponding clamping groove 711, when the damper 72 is opened, the limiting structure rotates with the rotating shaft 722, and when the limiting structure abuts against the fixed plate 71, the rotating shaft 722 is prevented from continuing to rotate, thereby limiting the damper 72 in the set open position, and the plurality of plate-shaped bodies 721 are arranged in parallel, and a guide air passage is formed between two adjacent plate-shaped bodies 721.

[0103] It should be noted that the shape of the plate-shaped body 721 of each damper 72 can be the same or different, and preferably the shape of the plate-shaped body 721 of each damper 72 is arranged according to the shape of the air outlet of the air blower 5.

[0104] For example, if the shape of the air outlet is square, the shape of the plate-shaped body 721 of each damper 72 can be the same, and if the shape of the air outlet is circular, the shape of the plate-shaped body 721 of each damper 72 is preferably matched with the shape of the air outlet at the mounting position of the damper 72.

[0105] In addition, it should be noted that the specific structure of the limiting structure is not limited in the utility model, for example, the limiting structure can be arranged as a limiting block, a limiting plate or a limiting column, etc.

[0106] Preferably, as shown in the drawings, Figures 6 to 11 The limiting structure is a limiting block 723, and the limiting block 723 has a stop surface 7231, and when the damper 72 is opened to the set open position, the stop surface 7231 abuts against the fixed plate 71.

[0107] Exemplarily, the shape of the limiting block 723 is approximately sectorial, and the end face of the top of the limiting block 723 is a stop face 7231.

[0108] Preferably, the limiting block 723 is provided with a hollow structure (not shown in the figure) near the stop face 7231.

[0109] By providing the hollow structure near the stop face 7231, the weight of the lower part of the limiting block 723 is greater than that of the upper part, which is more conducive to the closing of the air door 72 by its own gravity.
