[0035] Please refer to Figures 1 to 3 , the embodiment of the present application provides a filtering device 11.

[0036] The application scenario of the filtering device 11 is not limited. The filtering device 11 can filter impurities in the air flow according to the use scenario, and the impurities include lint, fluff, etc.

[0037] The embodiment of the present application is described by taking the filtering device 11 applied to a clothing treatment device as an example.

[0038] The embodiment of the present application provides a clothing treatment device, including a cylinder assembly, a drying air duct and the filtering device 11 according to any embodiment of the present application.

[0039] It should be noted that the clothing treatment device can be a drum washing machine with a drying function, or a washing and drying integrated machine, etc., which is not limited herein.

[0040] The cylinder assembly has a clothing treatment cavity, an air inlet and an air outlet.

[0041] Exemplarily, the cylinder assembly includes an inner cylinder and an outer cylinder. The outer cylinder is sleeved outside the inner cylinder. The outer cylinder is used to hold the water required for washing clothes, and the inner cylinder is used to hold clothes. The space inside the inner cylinder defines the clothing treatment cavity. Exemplarily, the inner cylinder and the outer cylinder are coaxially arranged inside and outside. There are holes on the side wall of the inner cylinder, and the water in the outer cylinder can enter the inner cylinder through the holes in the inner cylinder to wash the clothes in the clothing treatment cavity. In this embodiment, the inner cylinder can also be called a perforated inner cylinder.

[0042] The laundry treatment chamber is connected to an air inlet and an air outlet. When drying the laundry in the laundry treatment chamber, the dry hot air flow enters the laundry treatment chamber through the air inlet to perform heat and moisture exchange with the laundry in the laundry treatment chamber. The hot and humid air flow generated after the heat and moisture exchange leaves the laundry treatment chamber through the air outlet.

[0043] The inlet end of the drying air duct is connected to the air outlet, and the outlet end of the drying air duct is connected to the air inlet.

[0044] Specifically, after the hot and humid air flow leaves the laundry treatment chamber through the air outlet, it enters the drying air duct through the inlet end of the drying air duct. After condensation and dehumidification, a low-temperature dry air flow is formed, and then after heating, a dry hot air flow is formed. The dry hot air flow enters the laundry treatment chamber through the outlet end of the drying air duct.

[0045] Hereinafter, a brief description will be given of the drying process and principle of the laundry treatment device in this embodiment.

[0046] When the laundry treatment device performs a drying operation on the laundry, the dry hot air flow enters the laundry treatment chamber from the outlet end of the drying air duct through the air inlet. In the laundry treatment chamber, the dry hot air flow flows through the surface of the wet laundry, performs heat and moisture exchange with the wet laundry, absorbs the moisture in the laundry, and becomes a hot and humid air flow. The hot and humid air flow enters the inlet end of the drying air duct through the air outlet, and successively flows through the condensation and dehumidification member and the heating member. During the process of flowing through the condensation and dehumidification member, the water vapor in the hot and humid air flow precipitates from the air flow due to temperature reduction and condenses into water droplets. The hot and humid air flow is condensed and dehumidified by the condensation and dehumidification member to form a low-temperature dry air flow. The low-temperature dry air flow is heated into a dry hot air flow when passing through the heating member. The dry hot air flow enters the laundry treatment chamber again through the outlet end of the drying air duct and the air inlet, and circulates in this way to achieve continuous and efficient drying of the laundry.

[0047] It should be noted that the low-temperature dry air flow is relative to the hot and humid air flow, and the temperature of the low-temperature dry air flow is lower than that of the hot and humid air flow. The low temperature in the embodiment of the present application can be room temperature.

[0048] The filtering device 11 is arranged on the air flow path of the drying air duct for filtering the air flow passing through the drying air duct.

[0049] It can be understood that after the dry hot air flow performs heat and moisture exchange with the laundry in the laundry treatment chamber, it will inevitably carry the lint on the laundry. The lint is likely to adhere to various corners of the drying air duct after entering the drying air duct, affecting the drying efficiency and increasing the risk of lint dry burning, thereby affecting the service life of the laundry treatment device.

[0050] Therefore, in this embodiment, the filtering device 11 is provided to filter impurities such as lint carried by the air flow passing through the drying air duct, reduce the probability of the lint generated by the laundry adhering to the drying air duct, improve the drying efficiency, and reduce the risk of lint dry burning, thereby improving the working reliability and service life of the laundry treatment device.

[0051] Please refer to Figure 1 and Figure 2 , the filtering device 11 includes a filter cartridge 110 and a filter container 111.

[0052] The filter cartridge 110 has a receiving space 110a, an air inlet 110b, and an air outlet 110c, and the receiving space 110a communicates with the air inlet 110b and the air outlet 110c.

[0053] It can be understood that the air flow entering the filter cartridge 110 flows into the receiving space 110a through the air inlet 110b and then flows out through the air outlet 110c.

[0054] The filter container 111 is disposed in the receiving space 110a. The filter container 111 has an opening 111a, and the opening 111a communicates with the air inlet 110b so that the filter container 111 filters the air flow entering the filter cartridge 110.

[0055] It should be noted that the filter container 111 refers to a structure that has a filtering function and defines a storage space inside, and the storage space is used to store impurities such as lint filtered. Exemplarily, the filter container 111 can be in a cylindrical shape, a conical shape, etc.

[0056] Specifically, the air flow enters the filter container 111 through the opening 111a, and impurities such as lint carried in the air flow are intercepted and stored by the filter container 111, so that the impurity content in the air flow flowing out of the air outlet 110c is reduced. The filter cartridge 110 can provide a supporting effect for the filter container 111 so that the filter container 111 maintains the filtering ability and structural stability under the impact of the air flow.

[0057] It should be noted that the connection manner between the opening 111a and the air inlet 111b is not limited. Exemplarily, any part of the filter container 111 at the opening 111a fits against the inner wall of the filter cartridge 110. In some other examples, the edge of the opening 111a is connected to the edge of the air inlet 110b. In this way, it is convenient for the air flow to flow through the air inlet 110b and then flow through the opening 111a to enter the filter container 111 for filtering, reducing the probability of air leakage at the docking part of the opening 111a and the air inlet 110b.

[0058] In the related art, a layered filter screen is provided in the filtering device to filter lint. The filter screen is fixed inside the filter cartridge. When it is necessary to clean the filtering device, the filtering device needs to be taken out from the air duct of the laundry treatment device, and then the filter cartridge is opened to clean the filter screen from the inside of the filter cartridge, and the operation convenience is low. Moreover, part of the impurities carried by the air flow accumulates on the filter screen, and the other part accumulates in the filter cartridge. When cleaning the filter screen, the filter cartridge also needs to be cleaned.

[0059] In this embodiment, the filtering container 111 is provided. On the one hand, it can increase the filtering area of the filtering device 11, increase the flow rate of the air flow passing through the filtering container 111 per unit time, and improve the filtering efficiency of the filtering device 11. On the other hand, when the filtering container 111 needs to be cleaned, impurities such as lint accumulated in the filtering container 111 can be cleaned by scraping and pouring, without the need to remove the filtering box 110, and the cleaning convenience is high.

[0060] For the filtering device 11 provided in the embodiment of the present application, when the air flow passes through the filtering device 11, it first enters the filtering container 111 through the opening 111a. The filtering container 111 intercepts impurities such as lint carried in the air flow. In this way, when the filtering device 11 needs to be cleaned, on the one hand, the filtering container 111 can be cleaned by scraping, pouring, washing and other methods, without disassembling the filtering box 110, and the operation convenience is high. On the other hand, the air flow flowing from the filtering container 111 into the accommodation space 110a has a small content of impurities, reducing the probability of impurities such as lint sticking in the filtering box 110, and the filtering box 110 has a high cleanliness. Only the filtering container 111 needs to be cleaned, further increasing the cleaning convenience of the filtering device 11. In addition, the setting of the filtering container 111 can also increase the contact area with the air flow, increasing the filtering efficiency and filtering effect of the filtering device 11.

[0061] The specific structures of the condensation dehumidifying member and the heating member are not limited. Exemplarily, the condensation dehumidifying member can condense and dehumidify the air flow through condensed water, and the heating member can be a resistance wire heating.

[0062] In other embodiments, the clothing treatment device includes an evaporator and a condenser. The condensation dehumidifying member is the evaporator, and the heating member is the condenser.

[0063] The evaporator and the condenser are arranged in the drying air duct. The evaporator is arranged downstream of the filtering device 11 along the air flow direction, and the condenser is arranged downstream of the evaporator along the air flow direction.

[0064] That is to say, after the air flow enters the drying air duct, it first flows through the filtering device 11, and then contacts and exchanges heat with the evaporator and the condenser in sequence, and then leaves the drying air duct and enters the clothing treatment cavity.

[0065] Specifically, the hot and humid air flow leaves the clothing treatment cavity and enters the drying air duct. The impurities carried in the air flow are filtered by the filtering device 11. When flowing through the evaporator, it absorbs heat and reduces the temperature at the evaporator, becoming a low-temperature dry air flow. Then it flows through the condenser, absorbs heat at the condenser, and increases the temperature, becoming a dry hot air flow. The dry hot air flow leaves the drying air duct and enters the clothing treatment cavity again. In this way, it runs in a cycle to achieve continuous drying of the clothing.

[0066] In this embodiment, the filtering device 11 is arranged upstream of the evaporator and the condenser along the airflow direction. The humid and hot airflow must first pass through the filtering device 11 before entering the evaporator for condensation dehumidification and then entering the condenser for heating. In this way, the impurities carried by the humid and hot airflow are intercepted by the filtering device 11, reducing the probability that the impurities adhere to the evaporator and the condenser and affecting the working efficiency of the evaporator and the condenser, and improving the drying reliability and drying efficiency.

[0067] Moreover, the filtering device 11 is arranged near the inlet end of the drying air duct, which is also convenient for increasing the cleanliness of the drying air duct.

[0068] Of course, in some examples, the laundry treatment device further includes a compressor. The compressor is used to compress the refrigerant. The compressor has a suction port and a discharge port. The compressor sucks in the refrigerant with a lower temperature and a lower pressure from the suction port, and drives a piston to compress the refrigerant through the operation of the motor. The condenser is communicated with the discharge port of the compressor. The condenser is used to cool down the refrigerant. The condenser generates heat and then heats the airflow. The evaporator is communicated with the suction port of the compressor. The evaporator is used to heat up the refrigerant. The evaporator absorbs heat and then condenses and dehumidifies the airflow.

[0069] It can be understood that in some examples, the laundry treatment device further includes a heater. The heater is arranged in the drying air duct and downstream of the evaporator along the airflow direction. The heater is used to heat the airflow. That is to say, the heater and the condenser jointly heat the airflow. In this way, the drying temperature is increased and the drying efficiency is improved.

[0070] The filtering device 11 can also reduce the probability that impurities such as lint adhere to the heater, reduce the risk of lint dry burning, and further improve the working reliability and service life of the laundry treatment device.

[0071] In some examples, the drying air duct has a first interface, and the filtering device 11 is detachably docked with the first interface.

[0072] That is to say, the filtering device 11 is detachably matched with the drying air duct. When it is necessary to clean the filtering device 11, the filtering device 11 can be detached from the first interface, and then matched with the first interface after cleaning. In this way, it is convenient for the user to install and clean.

[0073] The filtering device 11 can be snap-connected, thread-connected, etc. with the first interface, which is not limited here.

[0074] Exemplarily, the first interface can be arranged at the inlet end of the drying air duct. In this way, the airflow entering the drying air duct can first enter the filtering device 11 for filtering.

[0075] In some embodiments, the filtering container 111 is detachably connected to the filtering cartridge 110 so that the entire filtering container 111 can be detached from the filtering cartridge 110. In this way, when it is necessary to clean the filtering container 111, the filtering container 111 can be directly detached from the filtering cartridge 110 to facilitate thorough cleaning of the filtering container 111. Moreover, when it is necessary to replace the filtering container 111, it is also convenient to replace the filtering container 111 without replacing the filtering cartridge 110 and the filtering container 111 together.

[0076] Exemplarily, the edge of the opening 111a of the filtering container 111 is detachably connected to the edge of the air inlet 110b of the filtering cartridge 110. When it is necessary to clean the filtering device 11, the docking between the edge of the opening 111a and the edge of the air inlet 110b is released, and the filtering container 111 is taken out from the accommodation space 110a through the air inlet 110b, and then the filtering container 111 is cleaned. After the cleaning is completed, the filtering container 111 is installed in the filtering cartridge 110, and the edge of the opening 111a is restored to be docked with the edge of the air inlet 110b. In this way, the operation is simple and convenient, improving the cleaning convenience of the filtering device 11.

[0077] Of course, in some other embodiments, the filtering container 111 may also be non-detachably connected to the filtering cartridge 110.

[0078] The specific structure of the filtering container 111 is not limited.

[0079] In some embodiments, please refer to Figure 2 and Figure 3 , the filtering container 111 includes a connection frame 1111 and a container body 1112. One end of the container body 1112 is connected to the connection frame 1111, and the connection frame 1111 is connected to the edge of the air inlet 110b.

[0080] Specifically, the connection frame 1111 is the structure on the filtering container 111 for connecting to the filtering cartridge 110, and the container body 1112 is the structure on the filtering container 111 for performing the filtering function. The connection frame 1111 defines the opening 111a. The connection frame 1111 is connected to the filtering cartridge 110. On the one hand, it connects the filtering cartridge 110 and the filtering container 111, making the filtering device 11 form an integral structure, facilitating the installation and removal of the filtering device 11. On the other hand, under the impact of the airflow, the filtering cartridge 110 provides a supporting force for the connection frame 1111, and further enables the filtering container 111 to maintain the filtering ability under the impact of the airflow.

[0081] Exemplarily, the connection frame 1111 can be a rigid structural member, which can not only facilitate the connection with the filtering cartridge 110 but also increase the connection strength, thereby increasing the connection reliability between the filtering container 111 and the filtering cartridge 110 and enhancing the stability of the filtering container 111 under the impact of the airflow.

[0082] It can be understood that the connecting frame 1111 can be detachably connected to the edge of the air inlet 110b or non-detachably connected to the edge of the air inlet 110b.

[0083] In some embodiments, the container body 1112 is a flexible structure so that the container body 1112 can extend into or out of the filter cartridge 110 from the opening 111a and the air inlet 110b.

[0084] It should be noted that the flexible structure is a structure that can be deformed under force.

[0085] That is to say, the container body 1112 can extend out of the filter cartridge 110 under the action of an external force, and the user can then clean the container body 1112 to remove lint. Moreover, since the container body 1112 is a flexible structure, it can be cleaned by kneading or other means. After cleaning, the container body 1112 can be cleaner. After cleaning, the container body 1112 can be re-extended into the filter cartridge 110 under the action of an external force. The whole process does not require operations to disconnect and reconnect the filter container 111 and the filter cartridge 110.

[0086] In this embodiment, there is no need to consider the connection method between the filter container 111 and the filter cartridge 110. Whether the connecting frame 1111 is detachably connected or non-detachably connected to the edge of the air inlet 110b, no disassembly operation is required. The container body 1112 can be directly pulled out of the filter cartridge 110 to clean the filter container 111, and after cleaning, the container body 1112 is put back into the filter cartridge 110, making the cleaning of the filter device 11 simpler and more convenient.

[0087] In some embodiments, the container body 1112 and the connecting frame 1111 are of an integral structure.

[0088] The integral structure is convenient for molding and can also reduce the assembly process of the filter device 11 and increase the assembly efficiency.

[0089] Of course, in some other embodiments, the container body 1112 and the connecting frame 1111 can also be of a split structure, that is to say, the container body 1112 and the connecting frame 1111 are formed separately and then assembled. In this way, it is convenient for the connecting frame 1111 to use materials with high strength and hardness, increasing the connection strength with the filter cartridge 110.

[0090] The detachable connection method between the connecting frame 1111 and the filter cartridge 110 is not limited and can be snap connection, threaded connection, etc.

[0091] For example, in some embodiments, please refer to Figure 2 and Figure 3, the connection box 1111 is formed with a slot 1111a, and the filter box 110 is provided with a rib 1101. The rib 1101 is arranged around the air inlet 110b, and the rib 1101 is inserted into the slot 1111a.

[0092] That is to say, when the connection box 1111 is connected to the filter box 110, the rib 1101 can be directly inserted into the slot 1111a to complete the docking. In this embodiment, through the arrangement of the structures of the connection box 1111 and the filter box 110 itself, the connection and cooperation between the filter box 110 and the connection box 1111 are completed without additionally arranging a connection structure. The connection method is simple. When it is necessary to disassemble the filter container 111 from the filter box 110, the cooperation between the rib 1101 and the slot 1111a can be directly released, and the disassembly is convenient.

[0093] Of course, in some other embodiments, the filter box 110 is provided with a slot, the slot is arranged around the air inlet 110b, the connection box 1111 is formed with a rib, and the rib is inserted into the slot.

[0094] In some embodiments, the slot width within at least a partial length range of the slot 1111a is smaller than the thickness of the rib 1101, and at least one of the slot walls of the slot 1111a and the rib 1101 can undergo elastic deformation so that the slot walls on both sides of the slot 1111a clamp the rib 1101 therebetween.

[0095] After the rib 1101 is inserted into the slot 1111a, under the elastic force of the slot walls of the slot 1111a and / or the rib 1101, the slot walls on both sides of the slot 1111a clamp the rib 1101, making it difficult for the rib 1101 to disengage from the slot 1111a, so that the rib 1101 and the slot 1111a are closely fitted, increasing the connection firmness between the connection box 1111 and the filter box 110 and reducing the probability that the connection between the connection box 1111 and the filter box 110 becomes loose under the impact of air flow.

[0096] It can be understood that during the docking process of the rib 1101 and the slot 1111a, it can be that only the slot walls of the slot 1111a undergo elastic deformation, or only the rib 1101 undergoes elastic deformation. Of course, it can also be that both the slot walls of the slot 1111a and the rib 1101 undergo elastic deformation.

[0097] In some embodiments, please refer to Figure 2 and Figure 3, along the direction away from the air inlet 110b, the cross-sectional area of the container body 1112 gradually decreases. In this way, the container body 1112 can have a sufficient filtration area. After the air flow is filtered at one end of the container body 1112 close to the air inlet 110b, impurities such as lint filtered out can accumulate at one end of the container body 1112 away from the air inlet 110b under the action of gravity and the scouring of the air flow, reducing the probability of blockage of the container body 1112, increasing the filtration effect, and also facilitating the cleaning of the container body 1112.

[0098] In some embodiments, please refer to Figure 1 and Figure 2 , the filtering device 11 includes a filter screen assembly 112, and the filter screen assembly 112 is connected to the filter box 110 and covers the air outlet 110c.

[0099] That is to say, the air flow enters the filtering device 11 from the air inlet 110b, is first filtered by the filtering container 111, and then is filtered again by the filter screen assembly 112 before flowing out of the filtering device 11 through the air outlet 110c. The filter screen assembly 112 can further reduce the impurities in the air flow. In this way, the air flow passes through at least two filtrations during the process of passing through the filtering device 11, and the filtering effect of the filtering device 11 can be further improved.

[0100] In some embodiments, please refer to Figure 1 and Figure 2 , one end of the filter box 110 along the first direction has a first side wall 1102, and the air outlet 110c is arranged on the first side wall 1102.

[0101] One end of the filter box 110 along the second direction has a second side wall 1103, and the air inlet 110b is arranged on the second side wall 1103.

[0102] The air inlet 110b and the air outlet 110c are arranged in different directions of the filter box 110, which is convenient for the docking of the filtering device 11 with other structures in different directions, and is also convenient for increasing the area of the air inlet 110b or the air outlet 110c, thereby increasing the air flow rate.

[0103] In some embodiments, the area of the air outlet 110c is not less than 1 / 2 of the area of the first side wall 1102.

[0104] In this way, the area of the air outlet 110c can be relatively large, and the air flow filtered by the filtering container 111 and the filter screen assembly 112 can flow out of the filtering device 11 relatively quickly, with a large air flow rate, improving the filtering efficiency of the filtering device 11.

[0105] In some embodiments, support ribs 1104 are arranged in the air outlet 110c to increase the structural strength at the air outlet 110c.

[0106] In some examples, the area of the air inlet 110b is not less than 1 / 2 of the area of the second side wall 1103.

[0107] In this way, the area of the air inlet 110b is relatively large, and the airflow entering the filtering device 11 per unit time can also be relatively large, which is convenient for the filtering container 111 and the filter screen assembly 112 to continuously filter the airflow, and increases the filtering reliability of the filtering device 11.

[0108] The specific structure of the filter cartridge 110 is not limited.

[0109] Exemplarily, please refer to Figure 1 and Figure 2 , the filter cartridge 110 includes a cartridge body 1105 and a cover body 1106. One side of the cartridge body 1105 in the thickness direction has an opening, and the cover body 1106 is detachably arranged at the opening for closing the opening. In this way, the components arranged in the cartridge body 1105 can be installed, disassembled or repaired through the opening, improving the convenience of maintenance of the filtering device 11.

[0110] The shape of the filter cartridge 110 is not limited. Exemplarily, the filter cartridge 110 is generally in a cuboid shape.
