[0042] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through an intermediate medium. 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.

[0043] As Figures 1 to 5As shown, the embodiment of the present application introduces a clothes treatment device, which comprises a drum 3, independently holds washing water when washing clothes, avoids the problem that washing water flows crosswise in and out of the drum 3 during the washing process of the washing machine, and causes the washing water to be polluted by the dirt and bacteria accumulated outside the drum; a drying system, which is used for drying treatment of the load in the drum to obtain dry clothes, and further achieves the effect of improving the quality of life of users.

[0044] In the embodiment of the present application, the drying system comprises an air duct 4, which is communicated with the drum 3 at both ends to form a circulating air path; a fan 40 is installed in the air duct 4, so that the circulating air path formed by the drum 3 and the air duct 4 forms a circulating airflow flowing in a single direction; a dehumidifying device 41 is further installed in the air duct 4 to dehumidify the circulating airflow, so as to reduce the humidity of the airflow in the circulating air path and achieve the effect of drying the load in the drum 3; at the same time, in order to improve the drying rate of the load in the drum 3 and accelerate the vaporization of water adsorbed in the load, a heating device 42 can be arranged in the air duct 4 to heat the circulating airflow, so as to improve the temperature in the drum 3 and accelerate the drying rate by heating the load in the drum 3.

[0045] In the embodiment of the present application, when the clothes treatment device executes a drying program, the drying system is started to be controlled, the circulating airflow is formed in the circulating air path formed by the air duct 4 and the drum 3 under the action of the fan 10, the circulating airflow fully contacts the load in the drum 3 when flowing through the drum 3, becomes a wet and hot drying air after carrying the water in the load, flows out of the drum 3 and flows into the air duct 4; after the wet and hot drying air flows into the air duct 4, it contacts the dehumidifying device 41 in the air duct 4, so that the wet and hot drying air flow becomes a dry and hot drying air flow and then returns to the drum 3, and the flow is continuously and repeatedly circulated. Preferably, in order to improve the drying rate, a heating device 42 can be additionally arranged in the air duct 4, so that the dry and hot drying air flow after the dehumidifying treatment of the dehumidifying device 41 contacts the heating device 42, is heated, forms a high-temperature dry and hot drying air flow, and then returns to the air duct.

[0046] In the embodiment of the present application, the drying system can be any existing device capable of dehumidifying and drying clothes, such as a heat pump system. The heat pump system is connected in series from the compressor, evaporator, throttling device, and condenser, forming a circulating flow channel for the circulation of refrigerant medium. The condenser and evaporator are installed in the air duct 4 of the clothes treatment device in sequence along the circulating air flow direction, so that the air flow from the drum 3 first exchanges heat with the evaporator to condense and separate the water vapor contained therein, and then exchanges heat with the condenser to be heated to form a high-temperature dry air flow. Finally, the high-temperature dry air flow is returned to the drum 3 to reduce the humidity in the drum and increase the temperature in the drum 3, thereby achieving the effect of drying the load in the drum 3. Thus, the evaporator of the heat pump system forms a dehumidifying device 41, and the condenser forms a heating device 42, thereby achieving the effect of drying the load in the drum.

[0047] In the embodiment of the present application, in order to ensure that the drum 3 can rotate around the shaft and be connected to the air duct 4 installed in the shell 1 of the clothes treatment device and fixed in the shell 1, the following settings are made:

[0048] As shown in Figure 1 In the embodiment of the present application, the clothes treatment device includes a shell 1, and the shell 1 is provided with an outer cylinder 2. The outer cylinder 2 is connected to the washing machine shell 1 through shock-absorbing suspension springs and shock-absorbing support rods at the top and bottom, respectively, so that the outer cylinder 2 can be vibrated and installed in the washing machine shell 1. The outer cylinder 2 is provided with a drum 3 coaxially arranged inside the outer cylinder 2. The outer cylinder 2 and the drum 3 are respectively formed by a cylindrical outer cylinder side wall 202 and a cylindrical drum side wall 302. The same side of the outer cylinder 2 and the drum 3 is provided with a corresponding opening, forming a drum opening 301 and an outer cylinder opening 201, respectively. The other side of the outer cylinder 2 and the drum 3 is sealed, forming a drum bottom 303 and an outer cylinder bottom 203, respectively. At the same time, the washing machine shell 1 is provided with a door 6 that can be opened outward, so that the outer cylinder opening 201 can be closed or opened by opening and closing the door 6. A drum door 7 is installed on the drum 3 and can be opened outward, so that the drum opening 301 can be closed or opened by opening and closing the drum door 7. Thus, the drum 3 can be installed in the outer cylinder 2 and can rotate around the shaft, and the drum 3 forms a closed water container during washing. The two ends of the air duct 4 are connected to the outer cylinder 2, and a gas permeable hole is provided on the drum 3 and connected to the outer cylinder 2. A gas permeable module 5 is installed at the gas permeable hole, so that the air duct 4 forms a circulating air path through the outer cylinder 2 and the drum 3 rotating around the shaft, and the load in the drum 3 can be dried.

[0049] In the embodiment of the present application, the center of the drum bottom 303 is coaxially arranged with the motor shaft of the washing machine driving motor to drive the rotation of the drum 1, and the drum 1 and the driving motor are fixedly installed on the outer drum 2. Preferably, the drum bottom 303 and the driving motor are arranged on the two sides of the outer drum bottom 203, the driving motor is fixedly connected with the outer drum 2, the motor shaft of the driving motor passes through the outer drum bottom 203 through a bearing and is coaxially fixedly connected with the drum bottom 303, and the motor shaft of the driving motor can rotate relative to the outer drum 2 to realize the installation of the drum 3 and the driving motor on the outer drum 2 and enable the drum 3 to rotate alone under the action of the driving motor to wash the internal clothes. Preferably, the motor shaft of the driving motor directly constitutes a drum shaft, and the drum shaft is coaxially fixedly connected with the drum bottom 303 of the drum 3.

[0050] As shown in Figures 1 to 5 In the embodiment of the present application, the drum 3 is provided with a gas permeable opening communicated with the air duct 4, and the gas permeable opening is provided with a gas permeable module 5 capable of allowing airflow to flow under the action of pressure difference on both sides; the gas permeable module 5 comprises a shell 54, the shell 54 surrounds a hollow channel 53, and the channel 53 is arranged with a blocking rib at both ends, the blocking rib separates the channel 53 at both ends into a plurality of hollow small holes 57, and each hollow small hole 57 communicates the inside and outside of the channel 53.

[0051] Through the above arrangement, the two sides of the gas permeable module 5 can be communicated through the hollow small holes 57 of the channel 53 at both ends, the airflow on both sides of the gas permeable module 5 can flow through the channel 53, and the purpose of free exchange and flow of the gas on both sides under the action of pressure difference is achieved; at the same time, a plurality of hollow small holes 57 are arranged at the end of the gas permeable module 5 to make the airflow flowing through the hollow small holes 57 flow uniformly, thereby improving the uniformity of the airflow flowing into the drum 3.

[0052] In the embodiment of the present application, the gas permeable module 5 is directly arranged at or close to the center of the drum 3, and the gas permeable module 5 is higher than the maximum water level of the drum 3 to ensure that the washing water of the drum will not directly flow out through the gas permeable module 5, so that the washing water in the drum 3 will not be discharged during the rotation of the drum 3.

[0053] Embodiment one

[0054] As shown in Figures 1 to 4 In the embodiment, a gas permeable module 5 is introduced, which comprises a shell 54, the shell 54 surrounds a hollow channel 53, and the channel 53 is arranged with a blocking rib at both ends, the blocking rib separates the channel 53 at both ends into a plurality of hollow small holes 57, and each hollow small hole 57 communicates the inside and outside of the channel 53.

[0055] Through the above setting, the two sides of the air permeable module 5 can be communicated through the hollow small holes 57 of the two end communication channels, realizing that the air flow on both sides of the air permeable module 5 can flow through the channel, achieving the purpose of free exchange of the gas on both sides under the action of pressure difference; at the same time, by arranging the plurality of hollow small holes 57 at the end of the air permeable module 5, the flowing air flow is uniformly distributed under the action of the hollow small holes 57, thereby improving the uniformity of the air flow flowing into the drum 3.

[0056] In the embodiment, the hollow small holes 57 at the two ends of the channel of the air permeable module 5 can be staggered, so that the flowing air flow does not directly pass through, but needs to pass through the deflection channel, thereby ensuring that the water wrapped in the air flow is intercepted by the deflection channel, effectively preventing the water flow from flowing out of the air permeable module. Of course, in the embodiment, the air permeable module 5 can also arrange the hollow small holes 57 at the two ends in any other form, which can still achieve the above invention purpose of the application.

[0057] Preferably, in the embodiment, the projections of the hollow small holes 57 at the two ends of the channel 53 in the same vertical section along the channel axis at least partially intersect, so that the channel 53 and the hollow small holes 57 at the two ends of the air permeable module 5 form a deflected air flow channel together, which can effectively intercept the water wrapped in the air flow and prevent the water flow from flowing out of the air permeable module 5.

[0058] As shown in Figure 2 and Figure 3 In the embodiment, the cross section of the channel 53 of the air permeable module 5 can be any shape, for example: circular, polygonal, oval, etc.; preferably, in the embodiment, in order to adapt to the shape of the drum 3, improve the ventilation efficiency and improve the air flow uniformity, the air permeable module 5 can be set as a disc, and the cross section of the ventilation channel 53 is circular.

[0059] In the embodiment, the two ends of the circular channel 53 are respectively the first end 51 and the second end 52, and each of the first end 51 and the second end 52 is respectively provided with a blocking rib, which is used to separate the first end 51 and the second end 52 into a plurality of hollow small holes 57, realizing the effect that the two ends of the channel 53 can respectively exchange air flow with the outside through the arranged hollow small holes 57.

[0060] In the embodiment, the blocking rib provided at the end of the channel 53 can be set as any shape and any arrangement structure; for example, the following settings:

[0061] As shown in Figure 2 and Figure 3As shown, in this embodiment, the two ends of the circular channel 53 are respectively provided with multiple radial straight ribs 55 that extend radially and are arranged at intervals, and at least one annular rib 56 that extends circumferentially; each radial straight rib 55 and each annular rib 56 are in the same cross section, so that each radial straight rib 55 and each annular rib 56 are connected one to one, so that each radial straight rib 55 and each annular rib 56 divides the end of the channel 53 into multiple hollow holes 57 arranged at intervals in different rings.

[0062] Preferably, in this embodiment, the multiple radial straight ribs 55 provided at the first end 51 and the second end 52 of the circular channel 53 are arranged symmetrically along the axis of the opposite end channel 53 at equal intervals.

[0063] Preferably, in this embodiment, the annular rib 56 is a circular annular rib 56 that is coaxially arranged with the end of the channel 53 and is in the shape of a ring; more preferably, in this embodiment, the first end 51 and the second end 52 of the channel 53 are each provided with a plurality of concentric circular annular ribs 56 with different diameters, so as to further increase the number of perforated holes 57 provided at the end of the channel 53.

[0064] In this embodiment, in order to achieve the staggered arrangement of the perforated holes 57 at both ends of the channel 53, the following settings can be made: the size of the annular ribs 56 at both ends of the channel 53 is not equal, so that the annular ribs 56 at the first end 51 and the second end 52 of the channel 53 are respectively in different circular cross sections, and the projections of the annular ribs 45 at the first end 51 and the second end 52 of the channel 53 along the axis of the channel 53 in the same vertical cross section are staggered in different concentric circles.

[0065] To further enhance the staggered arrangement of the perforated holes 57 at both ends of the channel 53, the following arrangement can be made: the radial straight ribs 55 at both ends of the channel 53 extend in different radial directions, so that the radial straight ribs 55 at the first end 51 and the second end 52 of the channel 53 are staggered in different radial directions along the projection of the channel 53 axis in the same vertical section.

[0066] like Figures 2 to 4 As shown, in this embodiment, the channel 53 is a tapered channel with a gradually narrowing radial dimension from the first end 51 to the second end 52. This tapered sidewall guides the water flowing into the channel 53 back to the first end 51, effectively preventing water that has accidentally flowed into the channel 53 from accumulating there. In this embodiment, to achieve the effect of the water trapped in the channel 53 flowing back to the first end 51 and then into the washing machine drum, the first end 51 of the channel 53 needs to face inwards towards the inside of the washing machine drum, and the second end 52 needs to face outwards towards the outside of the washing machine drum. This is necessary to prevent water from flowing out through the vent holes.

[0067] In the embodiment, the inner circumferential wall of the first end of the channel 53 is provided with a plurality of hollow holes 57 arranged at intervals, so that the lowest part of the first end 51 of the channel 53 is the hollow hole 57, thereby ensuring that the water flow trapped in the channel 53 can flow back to the first end 51 through the lowest hollow hole 57 when flowing back along the tapered side wall, further preventing the occurrence of water accumulation in the channel 53; at the same time, the inner circumferential wall of the second end 52 of the channel is provided with a ring-shaped rib 56 protruding towards the center of the channel, so as to shield the inner circumferential wall of the second end 52 of the channel 53 by using the ring-shaped rib 56, further ensuring that the water flowing into the channel 53 will not flow out of the second end 52, effectively reducing the possibility of water flowing out of the air permeable module 5.

[0068] As shown in Figures 2 to 4 In the embodiment, a circular through hole is arranged at the center of each end of the channel 53, and the circular through hole is coaxially arranged with the channel 53 and located at the intersection of each radial straight rib 55 of the corresponding end. By arranging a circular through hole at the center of each end of the channel 53, it is ensured that the circular through hole can be directly ventilated, thereby improving the air permeability of the channel.

[0069] In the embodiment, the air permeable module 5 can be integrally arranged with the drum 3 or separately arranged; when the air permeable module 5 and the drum 3 are separately arranged, the first end 51 of the channel 53 of the air permeable module 5 is provided with a ring-shaped mounting rib protruding radially outward, so as to one-way limit the air permeable module 5 by using the mounting rib, thereby achieving the fixed installation of the air permeable module 5 on the air permeation hole. At the same time, in the embodiment, the outer circumferential wall of the second end 52 of the channel 53 and the side wall of the channel 53 are connected and provided with a circular arc chamfer surface, so as to prevent the clothes from being clamped and scratched by using the circular arc chamfer surface.

[0070] As shown in Figures 1 to 5 In the embodiment, a clothes treatment device is also introduced, which comprises a drum 3 arranged in a housing 1 and constituting a sealed water container when the washing machine is in a washing state; the drum 3 is provided with at least one air permeable module 5 described above, so as to exchange air between the inside and outside of the drum 3 by using the air permeable module 5, thereby achieving the purpose of ventilation and air exchange between the drum 5 and the external air duct 4.

[0071] In the embodiment, the opposite ends of the drum 3 are respectively provided with at least one air permeation hole provided with the air permeable module 5, and the air permeation holes at the two ends of the drum 3 are respectively connected in communication with the air inlet end and the air outlet end of the air duct 4 outside the drum 3; the air permeable module 5 arranged at one end of the drum 3 is connected in communication with the air inlet end of the air duct 4; the air permeable module 5 arranged at the other end of the drum 3 is connected in communication with the air outlet end of the air duct 4. Thus, in the circulating air path formed by the drum 3 and the air duct 4, under the action of the air permeable modules 5 at different positions, a one-way circulating air flow is formed, thereby ensuring the normal operation of the drying process. In the embodiment, the end of the drum 3 connected in communication with the air outlet end of the air duct 4 is provided with a drum opening.

[0072] In this embodiment of the invention, the two opposite ends of the roller 3 are the roller bottom 303 and the roller door 301, respectively. At least one of the above-mentioned ventilation modules 5 is provided on the roller bottom 303 and / or the roller door 301. The ventilation modules 5 at both ends of the roller 3 are respectively connected to the air inlet and air outlet of the air duct 4 outside the roller 3 to achieve the effect of forming a circulating air path.

[0073] In this embodiment, the ventilation module 5 can be integrally formed with the roller 3; of course, the ventilation module 5 can also be installed at the ventilation hole on the roller 3, for example as follows: the housing 54 of the ventilation module 5 is correspondingly covered and assembled in the ventilation hole on the roller 3, and the outer periphery of the housing 54 is sealed and fitted with the inner wall of the ventilation hole; preferably, the housing 54 is sealed and fitted with the inner wall of the ventilation hole; more preferably, the outer periphery of the housing 54 protrudes from the ventilation hole and is in close contact with the roller 3 on the outer periphery of the ventilation hole, thereby improving the assembly stability of the ventilation module 5.

[0074] In this embodiment, the two ends of the channel 53 formed by the housing 54 of the ventilated module 5 are connected to the inside of the roller 3 and the outside of the roller 3, respectively; the first end 51 of the channel 53 of the ventilated module 5 faces the inside of the roller 3 and the second end 52 faces the outside of the roller 3, so as to ensure that the water flowing into the channel 53 is guided by the conical sidewall of the channel 53 and the baffles at both ends, so as to achieve the effect of the water accumulated in the ventilated module 5 flowing back to the roller 3.
