[0039] The laundry treating apparatus 100 according to an embodiment of the utility model will be described below with reference to the accompanying drawings.

[0040] Referring to Figures 1-8 According to the utility model embodiment, the laundry treating apparatus 100 can include a cabinet 10, a laundry treating drum assembly 20 and an air duct assembly 30.

[0041] Specifically, the laundry treating drum assembly 20 is arranged in the cabinet 10, the air duct assembly 30 is arranged in the cabinet 10, and the air duct assembly 30 has an air duct cavity 31, the air duct cavity 31 includes a heat exchange cavity 311 and a filter cavity 313, the filter cavity 313 is located upstream of the heat exchange cavity 311 in the airflow direction, and the filter cavity 313 and the heat exchange cavity 311 are communicated through an air passage 312, and the heat exchange cavity 311 is provided with a heat exchange member 35.

[0042] Among them, the heat exchange cavity 311 and the filter cavity 313 are arranged along the first direction. For example, in some embodiments, as shown in Figure 1 The first direction is the left-right direction, and the heat exchange cavity 311 and the filter cavity 313 are arranged along the left-right direction.

[0043] The heat exchange cavity 311 is provided with a heat exchange member 35, and the heat exchange member 35 is used for heat exchange of airflow. For example, in some embodiments, as shown in Figure 1 The heat exchange member 35 includes an evaporator 351 and a condenser 352, and the airflow is changed into dry hot airflow by heat exchange between the evaporator 351 and the condenser 352 and the airflow, so as to dry the laundry by using the dry hot airflow.

[0044] The laundry treating apparatus 100 further includes a first filter member 40, and the first filter member 40 is at least partially arranged in the filter cavity 313, and the first filter member 40 can be used for filtering impurities such as lint and fluff attached in the airflow. The filter cavity 313 is located upstream of the heat exchange cavity 311 in the airflow direction, so that the airflow flowing to the air duct cavity 31 first enters the filter cavity 313, and the airflow in the filter cavity 313 is filtered by the first filter member 40 and then enters the heat exchange cavity 311 through the air passage 312.

[0045] In the process of treating clothes by the clothes treatment drum assembly 20, lint and other impurities on the clothes can enter the air duct cavity 31 along with the flow of the air flow. The lint and other impurities are prone to adhere to the heat exchange member 35 in the air duct cavity 31, resulting in low heat exchange efficiency of the heat exchange member 35, and the lint and other impurities are also prone to repeatedly adhere to the clothes along with the circulation of the air flow, resulting in low cleanliness of the treated clothes. By filtering the air flow through the first filter member 40 in the filtering cavity 313, the lint and other impurities adhering to the air flow can be filtered, the filtered air flow can enter the heat exchange cavity 311 to exchange heat with the heat exchange member 35, the content of impurities in the air flow flowing into the heat exchange cavity 311 can be reduced, the heat exchange member 35 is less likely to adhere to the lint and other impurities, the content of impurities in the air flow is reduced, and the working efficiency of the air duct assembly 30 is improved and the clothes treatment is more clean.

[0046] However, by filtering the air flow through the first filter member 40, the lint and other impurities adhering to the air flow can accumulate on the first filter member 40, resulting in reduced filtering efficiency of the first filter member 40, and thus the first filter member 40 needs to be cleaned to remove the accumulated impurities thereon, thereby improving the filtering efficiency of the first filter member 40.

[0047] In some related technologies, the air duct assembly needs to be disassembled to expose the filter member to the outside, and then the filter member needs to be detached from the air duct assembly to clean the filter member, which is complicated to operate, time-consuming, and low in cleaning efficiency.

[0048] In the present application, the clothes treatment device 100 further includes a first cleaning assembly 90, the first cleaning assembly 90 is arranged in the air duct assembly 30, and the first cleaning assembly 90 is used for spraying water towards the first filter member 40 to clean the first filter member 40, which can remove the accumulated impurities on the first filter member 40, realize self-cleaning of the first filter member 40, and improve the filtering efficiency of the first filter member 40. The first filter member 40 does not need to be detached from the air duct assembly 30 to clean the first filter member 40, which is convenient to operate, reduces the time required for detaching the first filter member 40, shortens the cleaning time, and improves the cleaning efficiency.

[0049] According to the clothes treatment device 100 of the embodiment of the present application, spraying water towards the first filter member 40 by the first cleaning assembly 90 can remove the accumulated impurities on the first filter member 40, realize self-cleaning of the first filter member 40, improve the filtering efficiency of the first filter member 40, and is convenient to operate and high in cleaning efficiency.

[0050] The clothes treatment device 100 can be used at least for drying clothes and the like, for example, the clothes treatment device 100 can be a clothes dryer or a washing and drying integrated machine.

[0051] The inlet and the outlet of the air duct cavity 31 are communicated with the laundry treatment drum assembly 20, so that the air flow in the laundry treatment drum assembly 20 can enter the air duct cavity 31 through the inlet of the air duct cavity 31, and the air flow in the air duct cavity 31 can enter the laundry treatment drum assembly 20 through the outlet of the air duct cavity 31, thereby realizing the circulation of the air flow between the laundry treatment drum assembly 20 and the air duct cavity 31.

[0052] In some embodiments, the laundry treatment apparatus 100 is a clothes dryer, and the working process and the drying principle of the clothes dryer are as follows: the dry hot air flow in the air duct cavity 31 enters the laundry treatment drum assembly 20 through the outlet of the air duct cavity 31, the dry hot air flow flows through the surface of the wet clothes in the laundry treatment drum assembly 20 to exchange heat and moisture with the wet clothes, absorbs the moisture in the clothes, and forms a wet air flow. The wet air flow in the laundry treatment drum assembly 20 enters the air duct cavity 31 through the inlet of the air duct cavity 31, and the air duct assembly 30 comprises a heat exchange member such as an evaporator and a condenser, and the wet air flow exchanges heat with the heat exchange member in the air duct cavity 31 to form a dry hot air flow. The dry hot air flow in the air duct cavity 31 enters the laundry treatment drum assembly 20 through the outlet of the air duct cavity 31, and the above process is repeated to realize the circulation of the air flow and achieve the drying function. The drying air flow comprises different state air flows circulating between the laundry treatment drum assembly 20 and the air duct cavity 31, such as the dry hot air flow and the wet air flow.

[0053] The laundry treatment drum assembly 20 can comprise a double-barrel structure, for example, comprising an inner barrel and an outer barrel, and the outer barrel is stationary and the inner barrel rotates relative to the outer barrel to drive the clothes in the inner barrel to tumble up and down. The laundry treatment drum assembly 20 can also comprise a single-barrel structure, for example, a single barrel is stationary and a stirrer is suspended above the single barrel to agitate the clothes to treat the clothes in the single barrel, and the type of the laundry treatment drum assembly 20 can be flexibly selected.

[0054] In some embodiments, as shown in Figures 1-4 The air flow in the air duct assembly 30 at least partially passes through the first filter member 40 from bottom to top, so that the lint in the air flow is accumulated on the lower side of the first filter member 40. The first cleaning assembly 90 is located above the first filter member 40, so that the first cleaning assembly 90 sprays water on the first filter member 40 below, so that the lint on the lower side of the first filter member 40 is separated from the first filter member 40 under the action of the water sprayed downward by the first cleaning assembly 90, facilitating the discharge of the lint and achieving a better cleaning effect on the first filter member 40.

[0055] In some embodiments of the utility model, as shown in Figures 2-3 The first cleaning assembly 90 itself or the first cleaning assembly 90 and the air duct assembly 30 define a water inlet cavity 91, the first cleaning assembly 90 has a first spray hole 92, the first spray hole 92 is connected with the filter cavity 313 and the water inlet cavity 91, and the first spray hole 92 is arranged opposite to the first filter member 40 to spray water toward the first filter member 40.

[0056] The first spray hole 92 is arranged opposite to the first filter 40. The opposite arrangement can be directly opposite or partially staggered. The relative positions of the first spray hole 92 and the first filter 40 are flexibly arranged, so that the water sprayed by the first spray hole 92 towards the filter cavity 313 can be sprayed to the first filter 40.

[0057] For example, in some embodiments, as shown in Figure 3 , the first spray hole 92 is directly opposite to the first filter 40 in the up-down direction, so that the water sprayed by the first spray hole 92 towards the filter cavity 313 can be sprayed to the entire first filter 40. The water flow direction at the first spray hole 92 is shown by the arrow in Figure 3 , so as to clean the entire first filter 40. The impurities accumulated in each part of the first filter 40 can be washed away by water, and the cleaning effect is better.

[0058] The water in the water inlet cavity 91 can be sprayed towards the filter cavity 313 through the first spray hole 92, and the first spray hole 92 is arranged opposite to the first filter 40, so that the water in the water inlet cavity 91 can be sprayed to the first filter 40 through the first spray hole 92. The flow rate of water increases due to the reduction of the hole diameter. Therefore, the flow rate of water sprayed from the water inlet cavity 91 to the first filter 40 through the first spray hole 92 can be increased, and the force of water washing the first filter 40 is increased. The cleaning effect of the first filter 40 is better.

[0059] The water inlet cavity 91 can be flexibly selected. For example, in some embodiments, as shown in Figure 3 , the first cleaning assembly 90 itself defines the water inlet cavity 91. In other embodiments, the water inlet cavity 91 is defined between the first cleaning assembly 90 and the air duct assembly 30.

[0060] In some embodiments, the first cleaning assembly 90 includes a first water inlet pipe 911. A certain amount of water is introduced into the water inlet cavity 91 through the first water inlet pipe 911, so that the water amount in the water inlet cavity 91 is controllable. By controlling the water amount in the water inlet cavity 91, the water amount sprayed to the first filter 40 can be controlled, and the cleaning force of the first filter 40 is controlled. Different cleaning forces are regarded as different gears, which is beneficial to realize multi-gear cleaning of the first filter 40.

[0061] In some embodiments, as shown in Figures 1-3 , the first filter 40 extends along a second direction. The second direction is arranged at an angle to the first direction, for example, at a right angle or an acute angle. For example, in some specific embodiments, as shown in Figure 1 , the second direction is the front-back direction, and the first filter 40 extends along the front-back direction. The heat exchange cavity 311 and the filter cavity 313 are arranged along the left-right direction. The first direction is the left-right direction, and the second direction is arranged at a right angle to the first direction.

[0062] The water inlet cavity 91 extends along the second direction, the first spray holes 92 are multiple, and at least part of the first spray holes 92 are arranged along the second direction. The first filter element 40 extends along the second direction, and water in the water inlet cavity 91 is sprayed to each part of the first filter element 40 extending along the second direction through the multiple first spray holes 92 arranged along the second direction, so that the cleaning effect of each part of the first filter element 40 extending along the second direction is better.

[0063] In some embodiments, the water inlet cavity 91 extends along the second direction, the first spray holes 92 are multiple, and at least part of the first spray holes 92 are arranged along the first direction. The second direction is arranged at an angle with respect to the first direction. Water in the water inlet cavity 91 is sprayed to each part of the first filter element 40 extending along the first direction through the multiple first spray holes 92 arranged along the first direction, so that the cleaning effect of each part of the first filter element 40 extending along the first direction is better.

[0064] In some embodiments, as shown in Figure 3 The first cleaning assembly 90 includes a partition wall 93 and a cover body 94. The partition wall 93 is arranged opposite to the first filter element 40, the cover body 94 is connected to one side of the partition wall 93 away from the first filter element 40 and defines the water inlet cavity 91 with the partition wall 93, and the first spray holes 92 are arranged on the partition wall 93.

[0065] The partition wall 93 can be arranged in the filter cavity 313 (as shown in Figure 3 The partition wall 93 can be arranged outside the filter cavity 313, for example, the partition wall 93 is arranged on the upper side of the cavity wall of the filter cavity 313, and water is sprayed from the first spray holes 92 on the partition wall 93 to the inside of the filter cavity 313 on the lower side. The arrangement position of the partition wall 93 can be flexibly selected.

[0066] The partition wall 93 is arranged opposite to the first filter element 40. Here, the opposite arrangement can be directly opposite or partially staggered, so that water sprayed from the first spray holes 92 on the partition wall 93 to the filter cavity 313 can be sprayed to the first filter element 40. For example, in some specific embodiments, as shown in Figure 3 The partition wall 93 is directly opposite to the first filter element 40 along the up-down direction.

[0067] The cover body 94 and the partition wall 93 can define the water inlet cavity 91, so that water in the water inlet cavity 91 can flow out from the first spray holes 92 on the partition wall 93 as much as possible, which is beneficial to fully utilizing the water in the water inlet cavity 91 to clean the first filter element 40.

[0068] The cover body 94 and the partition wall 93 can be an integral piece or a split piece. For example, in some embodiments, the cover body 94 and the partition wall 93 are a split piece, and the cover body 94 and the partition wall 93 can be connected together by one or more of bolt connection, clamping, bonding, etc., which is firm and convenient to disassemble and assemble, facilitating subsequent maintenance or replacement. For example, in other embodiments, the cover body 94 and the partition wall 93 are an integral piece, so that the cover body 94 and the partition wall 93 are not easily separated, and the water inlet cavity 91 defined by the cover body 94 and the partition wall 93 is more reliable.

[0069] In some embodiments, as shown in Figures 3-4 The air duct assembly 30 includes a base 371 and a cover plate 372, and the cover plate 372 is arranged on the top of the base 371 to define a filter cavity 313 with the base 371.

[0070] The cover plate 372 has a relief hole, and the cover body 94 cooperates with the relief hole and protrudes from the relief hole. Here, the cooperation can be that the outer wall surface of the cover body 94 is pressed, fitted or partially gap fitted with the inner wall surface of the relief hole. Arranging the cover body 94 in the relief hole of the cover plate 372, that is, achieving plug-in cooperation of the cover body 94 and the cover plate 372, makes the installation of the cover body 94 on the air duct assembly 30 more stable and less likely to shake, and the process of water in the water inlet cavity 91 spraying to the first filter element 40 is more stable.

[0071] In some embodiments, as shown in Figures 3-4 The partition wall 93 is located above the first filter element 40, and at least a portion of the partition wall 93 forms an arc-shaped plate extending from bottom to top towards the heat exchange cavity 311.

[0072] The partition wall 93 is located above the first filter element 40, so that the water sprayed by the first spray hole 92 on the partition wall 93 can be sprayed downward to the first filter element 40 under the action of its own gravity, without the need to add a driving component for driving water to spray to the first filter element 40, which is conducive to simplifying the structure of the first cleaning assembly 90 and the air duct assembly 30.

[0073] The partition wall 93 is arranged as the above-mentioned arc-shaped plate, so that the partition wall 93 can guide the airflow in the filter cavity 313, and the airflow can more smoothly flow to the heat exchange cavity 311 under the guiding action of the arc-shaped plate in the upward and rightward direction, which is conducive to improving the heat exchange efficiency of the air duct assembly 30.

[0074] For example, in some specific embodiments, as shown in Figure 1 and Figures 3-4 The heat exchange cavity 311 is located on the right side of the filter cavity 313, the partition wall 93 forms an arc-shaped plate extending upward and to the right, and the tangent direction of the arc-shaped plate is upward and to the right, and the airflow in the filter cavity 313 flows as shown in Figure 4The arrow in the middle indicates the direction of the airflow. In the flow direction of the airflow, the arc-shaped plate is located downstream of the first filter 40, so that the airflow filtered by the first filter 40 can flow more smoothly upwards and to the right to the heat exchange cavity 311 under the guidance of the arc-shaped plate.

[0075] In some embodiments of the present application, as shown in Figures 6-7 The mounting bracket 60 is provided with a ventilation opening, and the first filter 40 covers the ventilation opening, that is, the ventilation opening is opposite to the first filter 40, so as to make the airflow not filtered by the first filter 40 pass through the ventilation opening and the first filter 40 to be filtered by the first filter 40.

[0076] The ventilation opening can be one or more. For example, in some embodiments, the ventilation opening is one, and the filtration area is large and the filtration efficiency is high. For another example, in some embodiments, the ventilation opening is multiple, and a rib section is arranged between adjacent ventilation openings, so that the mounting bracket 60 is not easy to break, which is beneficial to improve the structural strength of the mounting bracket 60 and make the installation of the first filter 40 on the mounting bracket 60 more stable.

[0077] The mounting bracket 60 divides the filter cavity 313 into a first chamber 314 and a second chamber 315, the first chamber 314 is located below the second chamber 315, the first chamber 314 is in communication with the inlet of the air duct cavity 31, and the second chamber 315 is in communication with the air passage 312.

[0078] The communication in the present application can be direct communication or indirect communication. Direct communication means that the two are directly communicated without other communication components therebetween. For example, the first chamber 314 is directly communicated with the inlet of the air duct cavity 31, which means that the first chamber 314 and the inlet of the air duct cavity 31 are not provided with other communication components therebetween, so that the airflow at the inlet of the air duct cavity 31 directly flows into the first chamber 314 without passing through other communication components.

[0079] Indirect communication means that the two are communicated through other connecting components. For example, the first chamber 314 is indirectly communicated with the inlet of the air duct cavity 31, which means that the first chamber 314 and the inlet of the air duct cavity 31 are provided with other communication components therebetween, so that the airflow at the inlet of the air duct cavity 31 flows into the first chamber 314 after passing through the other communication components.

[0080] After the airflow at the inlet of the air duct cavity 31 enters the first chamber 314, it flows upwards into the second chamber 315, and then enters the heat exchange cavity 311 from the air passage 312.

[0081] This configuration allows the filter chamber 313 to form a first chamber 314 and a second chamber 315 arranged vertically. On the one hand, it reduces the space occupied by the mounting bracket 60 and the first filter element 40 in the vertical direction without changing the size of the first filter element 40, thereby reducing the overall height of the garment processing equipment 100. On the other hand, the airflow flows from bottom to top between the first chamber 314 and the second chamber 315, which increases the contact area between the airflow and the first filter element 40, thereby improving the filtration efficiency.

[0082] Airflow enters the lower first chamber 314, is filtered by the first filter element 40, and then flows into the upper second chamber 315. This creates a downward airflow structure within the filter chamber 313, causing impurities such as lint in the airflow filtered by the first filter element 40 to accumulate on its lower surface. These impurities are more likely to fall downwards into the first chamber 314 under their own gravity, rather than being carried by the airflow through the first filter element 40 into the second chamber 315. This results in better airflow filtration, reducing the impurity content in the airflow of the second chamber 315, and consequently reducing the impurity content in the heat exchange chamber 311, thus improving the heat exchange efficiency of the air duct assembly 30.

[0083] Furthermore, when water is sprayed onto the first filter element 40 through the first spray hole 92, the water sprayed onto the first filter element 40 easily carries away the impurities accumulated on the lower surface of the first filter element 40 and falls downward into the first chamber 314 under the gravity of the water and the impurities. When the water comes into contact with the airflow in the filter chamber 313, it also easily carries away the impurities in the airflow and falls downward into the first chamber 314, thereby reducing the impurities accumulated on the first filter element 40 and the impurities carried in the airflow, which is conducive to further improving the cleaning effect of the first filter element 40 and the filtration effect of the airflow.

[0084] In some embodiments, such as Figure 1 and Figure 3 As shown, the first spray hole 92 is located above the first filter element 40, which extends obliquely from bottom to top towards the air outlet 312. The first filter element 40 can guide the water flowing downwards through it, causing the water to flow downwards and away from the air outlet 312 under the guidance of the first filter element 40. This, in turn, causes the water to carry the impurities accumulated on the first filter element 40 downwards and away from the air outlet 312.

[0085] Some of the impurities on the first filter element 40 fall downward with the water flow and leave the first filter element 40. Other impurities are easily guided by the first filter element 40 to flow downward with the water flow and accumulate at one end of the first filter element 40 in a direction away from the air outlet 312. The more impurities accumulate together, the easier it is for them to fall off the first filter element 40, which helps to reduce the impurities on the first filter element 40 and improves the tilting effect of the first filter element 40.

[0086] And the impurities are accumulated on the end of the first filter element 40 far from the air outlet 312, and the water sprayed by the first spray hole 92 is sprayed downward to the first filter element 40 and the impurities, so that the impurities are not easy to flow to the air outlet 312, which is beneficial to reduce the impurity content of the airflow in the second chamber 315, and the filtering effect of the airflow is better.

[0087] For example, in some specific embodiments, as shown in Figure 3 The air outlet 312 is located on the right side of the first filter element 40, and the first filter element 40 extends upward and to the right, so that after the water is sprayed by the first spray hole 92, the impurities are more accumulated on the lower left end of the first filter element 40 far from the air outlet 312, and the impurities are more accumulated and are more likely to fall from the first filter element 40.

[0088] In some embodiments, as shown in Figures 3-4 And Figure 7 The air duct assembly 30 has a through hole 34 communicating with the filtering chamber 313, and the mounting bracket 60 has a guide portion 61, and the first filter element 40 can be mounted to the mounting bracket 60 under the guidance of the guide portion 61 from the through hole 34. The first filter element 40 can be installed on the mounting bracket 60 or removed from the mounting bracket 60 through the through hole 34, and the operation of taking and placing the first filter element 40 is convenient, which is convenient for manual cleaning or replacement of the first filter element 40, and the first filter element 40 can realize self-cleaning and manual cleaning, and the cleaning mode is various.

[0089] The first filter element 40 is guided to be mounted to the mounting bracket 60 through the guide portion 61, which can reduce the possibility that the first filter element 40 is partially or completely misaligned with the mounting bracket 60, so that at least part of the first filter element 40 can be smoothly mounted to the mounting bracket 60 after passing through the through hole 34, which is beneficial to improve the mounting precision of the first filter element 40, stably mount the first filter element 40 in the air duct chamber 31 to perform filtering work, reduce the risk that the first filter element 40 shakes in the air duct chamber 31 or even falls from the mounting bracket 60, and improve the working stability of the first filter element 40.

[0090] In some embodiments of the present application, as shown in Figures 1-5 The air duct assembly 30 has a drain port 373 communicating with the filtering chamber 313. The drain port 373 is used for draining the water flowing through the first filter element 40, and the impurities such as dust accumulated on the first filter element 40 are easy to flow to the drain port 373 with the water and be drained, so that the sewage with impurities is not easy to remain in the filtering chamber 313, so that the impurities in the sewage are not easy to adhere to the airflow flowing to the filtering chamber 313 and then adhere to the first filter element 40, which is beneficial to improve the cleaning effect of the first filter element 40 and the filtering effect of the airflow in the filtering chamber 313.

[0091] The drain port 373 is located at the bottom wall or the lower part of the side wall of the filtering cavity 313, so that the water in the filtering cavity 313 is easily drained to the drain port 373 under the action of gravity, and the draining effect is good.

[0092] In some embodiments, as shown in Figures 3-4 The inner wall surface of the filtering cavity 313 has a water guide surface 374 extending from top to bottom towards the direction close to the drain port 373. The water guide surface 374 can guide the water flow in the filtering cavity 313, so that the water flow can flow more smoothly downwards and towards the drain port 373 under the guidance of the water guide surface 374, and then be drained, and the draining effect is good.

[0093] For example, in some specific embodiments, as shown in Figures 3-4 The drain port 373 is located at the lower left end of the filtering cavity 313, and the inner wall surface of the base 371 has a water guide surface 374 extending downwards and to the left. The flow direction of the water at the drain port 373 is shown by the arrow in Figure 3 , so that the sewage flowing through the first filter element 40 can flow more smoothly downwards and to the left to the drain port 373 under the guidance of the water guide surface 374 to be drained.
