[0058] Background

[0059] In recent years, with the continuous development of the fabric treatment equipment market, the consumption upgrade driven by the demand for quality life has led to continuous technological innovation and development in the washing machine industry for healthy washing and care needs, among which the demand for fabric treatment equipment has grown significantly. At present, there are three main air duct drying methods for fabric treatment equipment on the market: tap water cooling humid air, humid air exhaust, and ordinary refrigeration system dehumidification. Among them, fabric treatment equipment that uses tap water to cool humid air has the largest market share.

[0060] The air duct that uses tap water to condense wet air often adopts a structure in which the air is discharged from the rear tube and inletted from the front tube. However, this structure is prone to cause problems such as small air inlet area, high air inlet temperature, and heat accumulation at the panel. It not only affects the drying efficiency but also causes low drying uniformity and panel damage.

[0061] Based on this, Figure 1-Figure 4 As shown, the first aspect of the embodiment of the present application provides a drum-type fabric processing device, comprising:

[0062] The fabric treatment drum comprises an outer drum 100 and an inner drum 200 rotatably sleeved in the outer drum 100, and a clothing loading port is provided at the front side of the inner drum 200;

[0063] The door assembly 300 is installed at the front panel of the fabric processing device and is used to open or close the clothing loading port of the inner drum 200, wherein a glass bowl 301 protruding toward the inner side of the clothing loading port is formed on the door assembly 300;

[0064] A drying air duct 400 is formed between the outer drum 100 and the inner drum 200. The air inlet of the drying air duct 400 is located at the front side of the inner drum 200 and below the glass bowl 301. The air outlet of the drying air duct 400 is located at the rear side of the inner drum 200, so that the airflow in the inner drum 200 enters the drying air duct 400 from the front side of the inner drum 200 and is discharged into the inner drum 200 again through the rear side of the inner drum 200.

[0065] The water outlet 1000 is arranged at the front side of the fabric treatment drum and is located above the glass bowl 301 when the door assembly 300 closes the clothing inlet, and is used to flow cooling water downward when the fabric treatment device dries the clothes;

[0066] The cooling water flowing downward through the water outlet 1000 can flow through the glass bowl 301 and then flow into the drying duct 400 through the air inlet of the drying duct 400, so that the airflow can exchange heat with the cooling water before and after entering the drying duct 400.

[0067] The fabric processing equipment in the embodiment of the present application adopts a back-in and front-out air duct structure, which can greatly reduce the temperature at the front panel of the equipment and provide good protection for the electrical components in the front panel; the rear drum has a large air inlet area, a high radial velocity, an obvious hot air mixing effect, and good drying air uniformity to protect clothes; the door cleaning spray and the condensed water spray share a common water system, which saves costs while extending the heat exchange time between condensed water and hot and humid air, thereby improving the condensation effect.

[0068] Specifically, in the embodiment of the present application, the water outlet 1000 is arranged on the front side of the fabric treatment drum, and is located above the glass bowl 301 when the door assembly 300 closes the clothing inlet, so that the cooling water can flow directly through the glass bowl 301. This design allows the cooling water to condense and exchange heat with the airflow before and after entering the drying air duct 400, thereby improving the efficiency of heat exchange. At the same time, in the embodiment of the present application, the air outlet is arranged on the rear side of the fabric treatment drum, so that the air inlet area of ​​the fabric treatment drum becomes larger when the air is entering, and the radial velocity of the airflow when flowing into the fabric treatment drum is increased, thereby improving the airflow mixing effect in the fabric treatment drum, thereby making the drying air in the fabric treatment drum more uniform, and avoiding the problem of local overheating in the drum causing high temperature damage to the clothes. More specifically, since the water outlet 1000 of the drying air duct 400 is located on the front panel side of the device and above the glass bowl 301, the cooling water flowing out of the water outlet 1000 can also effectively cool the electrical components on the front panel side and the electrical components in the door assembly 300 without the need to set up a separate cooling water system to dissipate heat for these electrical components.

[0069] Furthermore, in some possible implementations, a first guide rib assembly 500 is provided on the glass bowl 301 , and the first guide rib assembly 500 is used to delay the flow time of cooling water on the glass bowl 301 .

[0070] In the embodiment of the present application, by providing the first guide rib assembly 500 on the glass bowl 301, the flow time of cooling water on the glass bowl 301 can be delayed, which means that the cooling water has a longer contact time with the hot air passing through the glass bowl 301, thereby improving the heat exchange efficiency.

[0071] Further, in some possible implementations, the first guide rib assembly 500 includes a plurality of first guide rib units 501, and the plurality of first guide rib units 501 are distributed in the height direction of the glass bowl 301;

[0072] Each of the first guide rib units 501 is arranged obliquely on the glass bowl 301 so that the cooling water flowing onto the first guide rib unit 501 can flow obliquely downward.

[0073] In the embodiment of the present application, by setting a plurality of groups of first guide rib units 501 on the glass bowl 301, and these units are distributed in the height direction of the glass bowl 301, the flow path and speed of the cooling water can be controlled more accurately, ensuring that the cooling water can be evenly distributed on the entire glass bowl 301. Each first guide rib unit 501 is tilted so that the cooling water flows obliquely downward, which can increase the flow distance and residence time of the cooling water on the glass bowl 301, thereby increasing the contact area and time with the hot air and improving the heat exchange efficiency. At the same time, the tilted guide rib units can guide the cooling water to form a specific flow pattern, reduce the direct impact of the water flow on the glass bowl 301, avoid splashing, and ensure that the water flow flows smoothly and continuously over the entire surface of the glass bowl 301.

[0074] Furthermore, in some possible implementations, the plurality of groups of first guide rib units 501 are designed so that the cooling water left from the upper first guide rib unit 501 can be retained on the lower first guide rib unit 501 adjacent thereto.

[0075] The cooling water in the embodiment of the present application flows from the upper guide rib unit to the lower guide rib unit, ensuring a continuous heat exchange process on the entire glass bowl 301, improving the efficiency and uniformity of the heat exchange, and the design enables the cooling water to cover more guide rib units, increasing the total contact area between the cooling water and the hot air, thereby improving the efficiency of the heat exchange.

[0076] In layman's terms, by designing the first guide rib assembly 500 according to the above-mentioned structure, when water flows out of the water outlet 1000, the cooling water first cleans the door glass bowl 301, and then flows into the drying air duct 400 in a waterfall shape under the guiding effect of the first guide rib assembly 500. This process not only ensures the cleanliness of the door assembly 300, but also improves the condensation effect of the hot and humid gas, reducing the waste of heat energy.

[0077] Furthermore, in some possible implementations, a second guide rib assembly 600 is further provided in the drying air duct 400 , and the second guide rib assembly 600 is used to delay the flow time of cooling water in the drying air duct 400 .

[0078] The second guide rib assembly 600 in the embodiment of the present application is designed to delay the flow time of cooling water in the drying air duct 400, which increases the contact time between cooling water and hot air, thereby improving the efficiency of heat exchange. By extending the residence time of cooling water in the drying air duct 400, more heat can be absorbed by cooling water, enhancing the condensation effect, helping to reduce the temperature and humidity of hot and humid air, and improving the drying quality.

[0079] Combination Figure 2 and Figure 3It can be seen that the hot and humid air flow first passes through the waterfall water flow on the lower side of the glass bowl 301 and enters the drying air duct 400. After the waterfall water flow has been heat exchanged once, it is thoroughly condensed for the second time at the second guide rib assembly 600 in the drying air duct 400, and then it flows all the way down with the water flow for the final heat exchange. After three heat exchanges, the hot and humid air has become low-temperature saturated humid air. Then, after being heated by electric heating, the air flow becomes high-temperature dry humid air. Finally, it passes through the fan 700 and the volute, and evenly enters the rear drum to dry the clothes therein.

[0080] Further, in some possible implementations, the drying air duct 400 includes a first air duct section 401 formed between the front of the inner drum 200 and the front of the outer drum 100, a second air duct section 402 formed between the bottom of the inner drum 200 and the bottom of the outer drum 100, and a third air duct section 403 formed between the rear of the inner drum 200 and the rear of the outer drum 100, and the first air duct section 401, the second air duct section 402 and the third air duct section 403 are connected in sequence;

[0081] An air inlet is formed at the upper end of the first air duct section 401, and an air outlet is formed at the upper end of the third air duct section 403;

[0082] A second guide rib assembly 600 is provided in the first air duct section 401 , and the second guide rib assembly 600 includes second guide ribs alternately arranged in sequence from top to bottom in the first air duct section 401 .

[0083] In the embodiment of the present application, by dividing the drying air duct 400 into three sequentially connected sections (first air duct section 401, second air duct section 402, third air duct section 403), more accurate and effective airflow control can be achieved, and each air duct section can be optimized for specific drying needs. The first air duct section 401 is provided with a second guide rib assembly 600, and these guide ribs are staggered, which can further delay the flow time of cooling water in the air duct, increase heat exchange and condensation effects, and improve energy efficiency.

[0084] Further, in some possible implementations, the second air duct segment 402 is an inclined air duct segment;

[0085] The second air duct section 402 extends obliquely downward from the rear of the fabric processing cylinder to the front of the fabric processing cylinder, and a drainage port is formed at the bottom end of the second air duct section 402 located on one side of the front of the fabric processing cylinder.

[0086] The inclined second air duct section 402 in the embodiment of the present application is designed to allow condensed water to flow naturally to the drain outlet, thereby reducing the retention of condensed water in the air duct, reducing the formation of scale and sediment, and also reducing the risk of corrosion to the equipment.

[0087] Further, in some possible implementations, the fabric processing device further includes:

[0088] The fan 700 and the heating element 800 are disposed in the second air duct section 402 , and are disposed close to the rear of the second air duct section 402 relative to the front and rear of the second air duct section 402 .

[0089] The fan 700 and the heating element 800 in the embodiment of the present application are arranged near the rear of the second air duct section 402, which can more effectively push the heated air to the front of the air duct, thereby optimizing the hot air circulation in the entire drying air duct 400. At the same time, the fan 700 and the heating element 800 are arranged at a high position in the second air duct section 402, which can also ensure that condensed water will not be sucked into the fan 700 and the electric heating part.

[0090] Further, in some possible implementations, the heating element 800 is disposed close to the front of the second air duct segment 402 relative to the fan 700 .

[0091] In the embodiment of the present application, the fan 700 is arranged close to the front of the second air duct section 402, so that the hot air is first heated by the electric heating tube, and then driven into the fabric processing cylinder by the fan 700. The mixing effect of the fan 700 makes the temperature at each location almost equal, avoiding the misjudgment of the air inlet temperature sensor package caused by uneven temperature, thereby improving the accuracy of temperature control.

[0092] Further, in some possible implementations, the fan 700 is a centrifugal fan disposed at the intersection of the second air duct segment 402 and the third air duct segment 403;

[0093] The air inlet of the centrifugal fan faces the air inlet direction of the second air duct section 402 , and the air outlet faces the air inlet direction of the third air duct section 403 .

[0094] Further, in some possible implementations, a drying air duct 400 having an air inlet at the front and an air outlet at the rear is defined between the inner cylinder 200 and the outer cylinder 100;

[0095] The height of the air inlet is set higher than the height of the air outlet.

[0096] In the embodiment of the present application, the air inlet is set at a higher position and the air outlet is set at a lower position, which conforms to the natural law of hot air rising, helps to promote the upward flow of hot air in the drying air duct 400, and improves the drying efficiency. The setting of the high-position air inlet and the low-position air outlet helps to achieve uniform distribution of hot air in the drying air duct 400, reduce drying dead corners, and improve drying uniformity.

[0097] Further, in some possible implementations, the lateral projection of the glass bowl 301 in the height direction includes a first guide section 3011 extending from top to bottom, and a second guide section 3012 connected to the bottom of the first guide section 3011 and extending downward;

[0098] The first guide section 3011 extends obliquely from the outer side of the fabric processing cylinder to the inner side when the door assembly 300 is in the closed state, and the second guide section 3012 extends from the inner side of the fabric processing cylinder to the outer side when the door assembly 300 is in the closed state.

[0099] Further, in some possible implementations, when the door assembly 300 is in a closed state, an inlet air flow channel 900 is defined between the second air guide section 3012 and the air inlet of the drying air duct 400;

[0100] The air inlet channel 900 extends obliquely downward from the inside of the fabric processing cylinder to the outside.

[0101] Furthermore, in some possible implementations, the fabric processing device also includes a display component, and the display component is disposed inside the door body component 300 .

[0102] Furthermore, in some possible implementations, the above-mentioned fabric processing device is preferably a washer-dryer.
