[0032] The embodiments of this application will be further described below with reference to the accompanying drawings.

[0033] like Figure 1 , Figure 2 and Figure 5 As shown, Figure 1 This is a schematic diagram of the overall drying structure provided in one embodiment of this application; Figure 2 yes Figure 1 An exploded view of the drying mechanism is shown. Figure 5 This is a partial schematic diagram of a washing machine provided in one embodiment of this application. Specifically, the drying structure includes: a water guide 100, a heating device 200, and a fan 210. The water guide 100 discharges water into the drum 300, which is connected to its bottom. The water guide 100 also includes a condensing air duct 140 with a first air outlet. A heating device 200 is connected to the first air outlet and heats the air flowing through the condensing air duct 140. The heating device 200 also has a second air outlet 230. The heated air is blown out from the second air outlet 230, which is connected to the inside of the drum 300 via a connecting device (not shown). Therefore, the air blown out from the second air outlet 230 enters the drum 300 to dry the clothes, removing moisture. The air then re-enters the condensing air duct 140 of the water guide 100 to condense the moisture, and then re-enters the heating device 200 from the first air outlet 111, forming a cycle. Because the condensing air duct 140 is used in the water guide 100 for condensation, the number of internal components in the washing machine is reduced, saving space.

[0034] Specifically, the water guide 100 includes a first chamber 110, a second chamber 120, and a third chamber 130, which are connected by a condensing air duct 140. The first chamber 110 can condense and remove moisture from the air that flows sequentially through the third chamber 130, the second chamber 120, and the first chamber 110 via the condensing air duct 140. It is understood that after the air in the drum 300 enters the water guide 100, the water in the second chamber 120 can also come into contact with the air and be condensed and cooled, before entering the first chamber 110 to separate the water from the air, preventing excessive contact with water and reducing the drying effect.

[0035] like Figure 2 and Figure 3 As shown, Figure 3 yes Figure 2The diagram shows a perspective view of the first cavity 110 of the drying structure. Specifically, the first cavity 110 is further provided with an air guide baffle 112, which divides the first cavity 110 into multiple cavities. Air entering the first cavity 110 from the condenser duct 140 first encounters the air guide baffle 112, then flows through the multiple cavities, and finally flows out from the first air outlet 111.

[0036] Understandably, the air entering the first cavity 110 from the condenser duct 140 is fully condensed in the first cavity 110 because it flows through multiple cavities, and then moisture is released, making the air flowing out of the first air outlet 111 drier.

[0037] like Figure 2 and Figure 4 As shown, Figure 4 yes Figure 2 The diagram shows the second chamber 120 of the drying structure. Specifically, the second chamber 120 is also provided with a water inlet 121 and a drain hole 122. The water inlet 121 is located on the side wall of the second chamber 120, and the drain hole 122 is located at the bottom of the second chamber 120. Water for washing clothes enters the second chamber 120 from the water inlet 121 and then flows down into the third chamber 130 from the drain hole 122.

[0038] Understandably, multiple water inlets 121 can be set to control the water flow. The number of water inlets 121 can be set according to actual needs and is not specifically limited here. Understandably, the opening or closing of water inlets 121 can be controlled according to the amount of laundry being washed.

[0039] like Figure 2 and Figure 5 As shown, specifically, a water outlet pipe 131 is provided at the bottom of the third chamber 130, which is connected to the inside of the drum 300 to deliver water to the inside of the drum 300 for washing. Specifically, during washing, water exits from the water inlet 121 of the second chamber 120, flows down through the drain hole 122 into the third chamber 130, and then flows into the drum 300 through the water outlet pipe 131. In addition, during drying, air in the drum 300 is driven by the fan 210, flowing from the water outlet pipe 131 into the third chamber 130, and then sequentially flowing through the second chamber 120 and the third chamber 130 to achieve condensation.

[0040] Specifically, a powder box 400 is provided between the second cavity 120 and the third cavity 130 for holding laundry detergent. During washing, the water flowing down from the drain hole 122 in the second cavity 120 first passes through the powder box 400. After the water and the laundry detergent in the powder box 400 are mixed, the water flows down into the third cavity 130 and then enters the drum 300 through the water outlet pipe 131 to wash the clothes.

[0041] Specifically, the powder dispenser 400 has multiple powder compartments, which can hold various laundry detergents. Understandably, the number of powder compartments can be set according to the actual space of the water guide 100, and is not specifically limited here.

[0042] Understandably, the water can be controlled to flow from the corresponding inlet 121 based on the location of the laundry detergent in the powder tank, thus preventing the various laundry detergents in the powder tank from mixing or causing damage to the clothes by using the wrong laundry detergent.

[0043] Specifically, the heating device 200 includes a first air inlet, and a heating wire 220 is disposed inside the first air inlet for heating the air from the condenser duct 140. During drying, the air flowing through the first cavity 110 flows from the first air outlet 111 to the first air inlet and enters the heating device. The heating wire 220 heats up, heating the air flowing into the first air inlet, thus turning it into dry, hot air that flows to the second air outlet 230 and then into the drum 300 to dry the washed clothes.

[0044] An embodiment of the present invention provides a washing machine, which includes the drying structure and drum 300 of the above embodiments, and therefore has at least all the beneficial effects brought about by the technical solutions of the above embodiments.

[0045] Specifically, the drum 300 is connected to the water guide 100 and the heating device 200, and the bottom of the drum 300 is provided with a drain outlet 310 for draining wastewater after washing.

[0046] Understandably, because the drum 300 is connected to the water guide 100 and the heating device 200, air can continuously circulate in the drum 300, the water guide 100 and the heating device 200 to dry the washed clothes.

[0047] Specifically, when washing clothes, the drain outlet 310 is closed; after washing for a certain period of time, the drain outlet 310 is opened to remove the wastewater after washing.

[0048] Understandably, the washing time can be set according to the actual situation, and will not be specifically limited here.

[0049] Specifically, when the washing machine dries clothes, it first turns on the fan 210, causing air to circulate sequentially through the drum 300, water guide 100, and heating device 200. The heating wire 220 heats up, gradually heating the flowing air. The heated air enters the drum 300 through the second air outlet 230, comes into contact with the washed wet clothes, exchanges heat, and removes moisture from the clothes. Then, it enters the condenser duct 140 of the water guide 100 through the drain pipe, and sequentially passes through the third chamber 130, the second chamber 120, and the first chamber. When air enters the second cavity 120, it comes into contact with the residual moisture in the second cavity 120 and is condensed and cooled, releasing moisture. Then it enters the first cavity 110 to continue to condense and release moisture. Since the first cavity 110 is equipped with an air guide baffle 112, the air can stay in the first cavity 110 for a longer time, and the air is fully condensed and releases moisture. Then it enters the heating device 200 from the first air outlet 111. The heating wire 220 of the heating device 200 continues to heat the air. This cycle continues, thereby realizing the drying function of the washing machine.

[0050] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
