Description

TECHNICAL FIELD

[0001] The present application relates to a clothes treatment device in a household appliance, in particular, to a clothes treatment device with a non-porous drum and drying function, especially to a drum-type washer-dryer with a non-porous drum without dehydration holes, and particularly to a door structure applied to the clothes treatment device. BACKGROUND

[0002] With the improvement of people's living standards, washer-dryers, clothes dryers and other devices with clothes drying function have gradually entered the families of the public. However, the existing washer-dryers, clothes dryers and other devices generally connect an air duct to the outer drum, and set a fan in the air duct to extract the humid air in the outer drum, thereby reducing the humidity in the drum to dry the clothes.

[0003] Washing machines can be generally divided into pulsator washing machines, agitator washing machines and drum washing machines. Generally, washing machines remove stains from washing materials through the action of water and detergent.

[0004] Pulsator washing machines rotate a pulsator in the center of a washing tub left and right to perform washing operations. Agitator washing machines rotate an agitator in the center of a washing tub left and right to perform washing operations by using the friction between water flow and washing materials. Drum washing machines rotate a drum to tumble clothes and perform washing operations.

[0006] However, the current washing machines, whether pulsator or drum, generally have a large amount of dirt between the inner and outer drums. In order to avoid pollution of the washing water, the applicant previously proposed a non-porous drum washing machine that combines the inner and outer drums to overcome the problem of dirt remaining between the inner and outer drums.

[0007] Therefore, how to apply the non-porous drum technology to washer-dryers with drying function has become a research hotspot.

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments will be described clearly and completely below in combination with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but not to limit the scope of the present application.

[0037] In the description of the present application, it should be noted that the orientation or position relationship indicated by the terms "upper", "lower", "inner", "outer" and the like is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as a limitation on the present application. The device or element indicated thereby must have a particular orientation, be constructed and operated in a particular orientation.

[0038] 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.

[0039] As Figures 1 to 7 shown in the embodiment of the present application, a clothes treatment device is introduced, which comprises a drum 2, which independently holds washing water when washing clothes, avoiding the problem that washing water flows crosswise between the inside and outside of the drum 2 during the washing process of the washing machine, causing the washing water to be contaminated by the dirt and bacteria accumulated outside the drum; a drying system, which is used for drying treatment of the load in the drum 2 to obtain dry clothes, etc., thereby achieving the effect of improving the quality of life of users.

[0040] In the embodiment of the present application, the drying system comprises an air duct 5, which is connected to the drum 2 at both ends to form a circulating air path; a fan 4 is installed in the air duct 5, so that the circulating air path formed by the drum 2 and the air duct 5 forms a circulating airflow flowing in a single direction; a dehumidifying device 20 is also installed in the air duct 5 to dehumidify the circulating airflow flowing therethrough, 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 2; at the same time, in the embodiment of the present application, in order to improve the drying rate of the load in the drum 2 and accelerate the vaporization of water adsorbed in the load, a heating device 3 can be arranged in the air duct 5 to heat the circulating airflow flowing therethrough, thereby achieving the effect of improving the temperature in the drum 2 and accelerating the drying rate by heating the load in the drum 2.

[0041] In the embodiment of the present application, when the clothes treatment device executes a drying program, the drying system is controlled to start, and the circulating airflow is formed in the circulating air path formed by the air duct 5 and the drum 2 under the action of the fan 4; the circulating airflow fully contacts the load in the drum 2 when flowing through the drum 2, becomes a wet and hot drying airflow after carrying the water in the load, flows out of the drum 2 and flows into the air duct 5; after the wet and hot drying airflow flows into the air duct 5, it contacts the dehumidifying device 20 in the air duct 5, so that the wet and hot drying airflow becomes a dry and hot drying airflow and then flows back into the drum 2, and this continues to flow back and forth.

Finally, the high-temperature dry air flow is returned to the drum 2 to reduce the humidity and increase the temperature in the drum 2, thereby achieving the effect of drying the load in the drum 2.

[0078] In this embodiment, the hollow holes 802 at both ends of the channel of the breathable module 8 can be arranged alternately, so that the airflow flowing through cannot directly pass through, but needs to pass through the back-turning channel, thereby ensuring that the water wrapped in the airflow is intercepted by the back-turning channel, effectively preventing the water from flowing out of the breathable module 8. Of course, in this embodiment, the breathable module 8 can also arrange the hollow holes 802 at both ends in any other form, which can still achieve the above-mentioned purpose of the present application.

[0079] Preferably, in this embodiment, the projections of the hollow holes 802 at both ends of the channel in the same vertical section along the channel axis at least partially intersect, so that the channel of the breathable module 8 and the hollow holes 802 at both ends form a back-turning gas channel, which can effectively intercept the water wrapped in the airflow and prevent the water from flowing out of the breathable module 8.

[0080] The cross-section of the ventilation module 8 can be any shape, such as: circle, polygon, ellipse, etc.; preferably, in this embodiment, in order to adapt to the shape of the roller 2, improve ventilation efficiency and improve airflow uniformity, the ventilation module 8 can be set as a disc shape, and the cross-section of the ventilation channel is set as a circle.

[0081] In this embodiment, the two ends of the circular channel are a first end 81 and a second end 82, respectively. Each of the first end 81 and the second end 82 is provided with a baffle 803. The baffle 803 is used to divide the first end 81 and the second end 82 into multiple hollow holes 802, so that the two ends of the channel can exchange airflow with the outside through the arranged hollow holes 802.

[0082] In this embodiment, the channel is a tapered channel with a gradually narrowing radial dimension from the first end 81 to the second end 82. The tapered sidewalls of the channel guide the water flowing into the channel back to the first end 81, effectively preventing water that has accidentally flowed into the channel from accumulating inside. In this embodiment, to achieve the effect of the water trapped in the channel flowing back to the first end 81 and then into the washing machine drum, the first end 81 of the channel needs to face inwards towards the inside of the washing machine drum, and the second end 82 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.

[0083] In this embodiment, the inner peripheral wall of the first end 81 of the channel is provided with a plurality of hollow holes 802 arranged at intervals, so that the lowest point of the first end 81 of the channel is a hollow hole 802, thereby ensuring that when the water flow intercepted in the channel flows back to the first end 81 along the conical sidewall, it can flow back to the roller 2 through the hollow hole 802 at the lowest point, and further prevent water accumulation in the channel.

[0084] Preferably, in this embodiment, the breathable module 8 can be integrally formed with the roller 2, or it can be formed separately;

[0085] Preferably, in this embodiment, the outer periphery where the second end 82 of the channel of the breathable module 8 is connected to the channel sidewall is provided with a rounded chamfered surface, so as to prevent problems such as clothing being pinched or scratched by the rounded chamfered surface.

Thus, in the circulating air path formed by the drum 2 and the air duct 5, a unidirectional circulating airflow is formed under the action of the ventilation modules 8 at different locations, thereby ensuring the normal operation of the drying process. In this embodiment, the end of the drum 2 connected to the air outlet of the air duct 5 is provided with a cylinder opening.

[0094] In the embodiment, the air guide channel 9 is flat as a whole, the closed end 702 of the air guide channel 9 is a circular arc surface 703 narrowing from the open end to the closed end 702, and the side wall of the air guide channel 9 close to the door body 7 is composed of an inclined surface gradually inclined to the open end from the outer edge of the door body 7 to the middle part of the door body 7.

[0095] Preferably, in the embodiment, the circular arc surface 703 of the air guide channel 9 is coaxially arranged with the drum 2 to effectively guide the airflow to flow into the inside of the drum 2 along the axis direction of the drum 2 from the drum opening 201.

[0096] Preferably, in the embodiment, the side wall of the air guide channel 9 close to the door body 7 is composed of an inclined surface gradually inclined to the open end from top to bottom, so as to effectively guide the airflow flowing out of the air guide channel 5 to flow into the inside of the drum 2.

[0097] As shown in the drawings, in the embodiment, the drum door 10 is provided with the air permeable module 8 communicating the two sides, and the air outlet 13 of the air guide channel 9 is arranged towards the air permeable module 8. Figure 1

[0098] Preferably, the air permeable module 8 can be any air permeable structure in the prior art which can realize the air exchange effect between the inside and outside of the drum 2, for example, the air permeable module 8 described in the above embodiment.
