[0060] Please refer to Figure 1 As shown, this application provides a washing machine 100, which is a pulsator washing machine 100 and can wash and dry clothes. Of course, this washing machine 100 can also perform other treatments on clothes, such as soaking, spinning, etc.

[0061] In some embodiments of this application, please refer to Figure 1 and Figure 2 As shown, this washing machine 100 may include a housing 110. This housing 110 encloses a cylindrical shape extending vertically, and its overall shape is rectangular. Of course, it may be other shapes, such as circular, rhombic, etc., which are not limited herein. The housing 110 is a hollow structure, and other component structures, such as a circuit structure, a drive structure, etc., may be provided inside it.

[0062] In some embodiments of this application, please refer to Figure 2 As shown, this washing machine 100 may further include an outer tub 120. The outer tub 120 may be provided in a hollow cylindrical shape, or may be other shapes, such as spherical. The outer tub 120 is fixedly installed inside the housing 110, and the outer tub 120 forms a receiving space 121 with an upper opening for receiving washing water.

[0063] In some embodiments of the present application, please refer to Figure 2 As shown, this washing machine 100 may further include an inner tub 130. The inner tub 130 may have the same shape as the outer tub 120, such as a cylindrical shape or a spherical structure. The inner tub 130 is disposed inside the outer tub 120 and is rotatably provided about an axis in the vertical direction within the accommodation space 121, that is, the inner tub 130 can be rotatably disposed inside the outer tub 120. A washing cavity 131 with an open upper end may be provided inside the inner tub 130 for washing and accommodating clothes.

[0064] In some embodiments of the present application, please refer to Figure 2 or Figure 3 As shown, the outer tub 120 may be provided with a drain port 122. The drain port 122 may be provided at the bottom side of the outer tub 120 so that the washing water can be discharged from the accommodation space 121 in a timely and convenient manner.

[0065] In some embodiments of the present application, please refer to Figure 2 As shown, the outer tub 120 may be provided with an air inlet. Hot air can enter the accommodation space 121 inside the outer tub 120 through the air inlet, and then enter the washing cavity 131 inside the inner tub 130 to dry the clothes in the washing cavity 131.

[0066] In some embodiments of the present application, the outer tub 120 may be provided with an air outlet. During the drying process of the clothes, the hot air gradually takes away the moisture on the clothes, and the hot air gradually becomes humid and hot gas. The humid and hot gas can flow from the washing cavity 131 into the accommodation space 121 and be discharged through the air outlet.

[0067] In some embodiments of the present application, the outer tub 120 may be provided with at least two air outlets. During the drying process of the clothes, the hot air will gradually take away the moisture on the clothes, and the hot air gradually becomes humid and hot gas. The humid and hot gas can flow from the washing cavity 131 into the accommodation space 121 and be discharged through at least two air outlets. Discharging through at least two air outlets can increase the discharge amount of the humid and hot gas, and thus can timely discharge the humid and hot gas in the accommodation space 121 and timely dry the clothes.

[0068] In some embodiments of the present application, the inner tub 130 may be formed with water passing holes. The water passing holes may be formed on the circumferential side wall of the inner tub 130. Clothes are placed in the washing cavity 131, and the outer tub 120 is used for holding water and draining water. During the dehydration process, the water liquid in the washing cavity 131 can be discharged to the outer tub 120 through the water passing holes, and then discharged to the outside through the drain port 122 of the outer tub 120. In addition, when drying the clothes, the humid and hot gas in the inner tub 130 can also flow into the accommodation space 121 of the outer tub 120 through the water passing holes to discharge the humid and hot gas.

[0069] In some embodiments of the present application, please refer to Figure 4 As shown, this washing machine 100 may include a return air duct. The return air duct may be provided inside the housing 110, corresponding to the air outlet. The air inlet end of the return air duct is communicated with the air outlet, and the humid and hot gas discharged from the air outlet enters the return air duct to discharge the humid and hot gas in the washing cavity 131.

[0070] In some embodiments of the present application, please refer to Figure 4 As shown, this washing machine 100 may further include at least two return air ducts. These at least two return air ducts may be provided inside the housing 110 or outside the housing 110, and can be specifically designed according to different embodiments. The return air ducts correspond to the air outlets one by one, that is, the number of return air ducts corresponds to the number of air outlets. Through at least two return air ducts and two air outlets, the humid and hot gas in the washing cavity 131 can be discharged in time, and the clothes can be dried in time.

[0071] In some embodiments of the present application, please refer to Figure 2 or Figure 4 As shown, this washing machine 100 may further include an air inlet pipe 150. This air inlet pipe 150 may be provided inside the housing 110.

[0072] In some embodiments of the present application, please refer to Figure 4 As shown, the air inlet pipe 150 may include an air inlet end. The air inlet end of this air inlet pipe 150 is provided at one end of the air inlet pipe 150, and the air inlet end of this air inlet pipe 150 may be communicated with the air outlet ends of all the above-mentioned return air ducts. That is, the humid and hot gas discharged from the air outlet of the outer tub 120 enters the air inlet pipe 150 after passing through the return air ducts. All the return air ducts converge at the air inlet end of this air inlet pipe 150, saving the number of air inlet pipes 150 and optimizing the space inside the housing 110.

[0073] In some embodiments of the present application, please refer to Figures 4 to 6 As shown, the air inlet pipe 150 may further include an air outlet end. The air outlet end of the air inlet pipe 150 is communicated with the air inlet end of the air inlet pipe 150, and the air outlet end of the air inlet pipe 150 is communicated with the air inlet of the outer tub 120, so as to be able to blow the hot air described below into the washing cavity 131 to dry the clothes in the washing cavity 131.

[0074] In some embodiments of the present application, please refer to Figure 2 or Figure 4As shown, the washing machine 100 may further include a heating component 160. The heating component 160 may be disposed in the air inlet duct 150 and can be used to heat the gas entering the air inlet duct 150, and then blow the heated hot air into the washing cavity 131 through the air outlet end of the air inlet duct 150 and the air inlet of the outer tub 120 to dry the clothes in the washing cavity 131.

[0075] The washing machine 100 in the solution of this application includes a housing 110, an outer tub 120, an inner tub 130, an air inlet duct 150, a heating component 160, and at least two return air ducts. The clothes to be dried are placed in the washing cavity 131. After the heating component 160 heats the gas, it is discharged into the washing cavity 131 through the air outlet end of the air inlet duct 150 and the air inlet of the outer tub 120, and the hot air is used to dry the clothes in the washing cavity 131. After the drying is completed, the humid and hot gas flows from the washing cavity 131 into the accommodating space 121, and then flows out from the air outlet of the accommodating space 121 into the return air duct and gradually flows into the air inlet duct 150. The heating component 160 is used to heat the gas, and then the clothes in the washing cavity 131 are dried again, so as to realize the cyclic drying process of the clothes.

[0076] By providing at least two return air ducts in the housing 110 in this application, the gas flow rate of the gas flowing from the washing cavity 131 into the return air duct can be increased, and then the gas flow rate flowing into the air inlet duct 150 can be increased, so that the hot air flow rate released into the washing cavity 131 can be increased, and thus the drying duration can be reduced and the drying efficiency can be improved.

[0077] In some embodiments of this application, please refer to Figure 2 or Figure 4 As shown, at least two air outlets on the outer tub 120 may include a first air outlet 123a and a second air outlet 123b. The humid and hot gas in the washing cavity 131 can be discharged through the first air outlet 123a and the second air outlet 123b, improving the discharge flow rate of the humid and hot gas and timely discharging the humid and hot gas in the washing cavity 131, which can improve the drying efficiency of the clothes.

[0078] In some embodiments of this application, please refer to Figure 4As shown, these at least two return air ducts may include a first return air duct 140a and a second return air duct 140b. The air inlet end of the first return air duct 140a is correspondingly communicated with the first air outlet 123a, and the air inlet end of the second return air duct 140b is correspondingly communicated with the second air outlet 123b. By arranging two return air ducts outside the outer barrel 120 for circulation, the flow rate of the circulating air is increased, thereby increasing the gas flow rate flowing into the air inlet pipe 150, and also increasing the gas flow rate of the hot air flowing into the washing chamber 131, increasing the contact surface between the drying air and the clothes, accelerating the evaporation of moisture on the wet clothes, and improving the drying efficiency.

[0079] In some embodiments of the present application, please refer to Figure 4 As shown, the first air outlet 123a and the second air outlet 123b may be arranged on the side wall of the outer barrel 120. The first air outlet 123a and the second air outlet 123b may be arranged at the bottom of the outer barrel 120, so that the hot and humid gas in the washing chamber 131 can be more easily discharged into the first return air duct 140a and the second return air duct 140b, improving the discharge rate of the hot and humid gas, and thus improving the drying efficiency of the clothes.

[0080] It should be noted that the first air outlet 123a and the second air outlet 123b are not limited to being arranged at the bottom of the outer barrel 120, and may also be arranged at other positions, for example, in the middle of the outer barrel 120, at the bottom side of the outer barrel 120.

[0081] In some embodiments of the present application, the first return air duct 140a may be arranged on the back side of the housing 110 to optimize the internal space of the housing 110. The air outlet end of the first return air duct 140a may be arranged at the top of the housing 110, facilitating the release of hot air from top to bottom, enabling the washing chamber 131 to be filled with hot air, and improving the drying efficiency.

[0082] In some embodiments of the present application, the second return air duct 140b may also be arranged on the back side of the housing 110. Of course, the second return air duct 140b may also be arranged on the other sides of the housing 110, such as the front side, the left side or the right side, etc. Arranging the second return air duct 140b on the back side of the housing 110 can optimize the internal space of the housing 110. Arranging the air outlet end of the second return air duct 140b at the top of the housing 110 facilitates the release of hot air from top to bottom, enabling the washing chamber 131 to be filled with hot air, and improving the drying efficiency.

[0083] In some embodiments of the present application, please refer to Figure 4As shown, the washing machine 100 may further include a first condenser 170a. The first condenser 170a may adopt an air-cooled or water-cooled structure. The first condenser 170a may be detachably disposed in the first return air duct 140a. The cross-sectional area of the first condenser 170a may be the same as that of the first return air duct 140a to prevent the leakage of hot and humid gas from the gap between the first condenser 170a and the first return air duct 140a and ensure the condensation effect on the hot and humid gas. The first condenser 170a can condense the hot and humid gas discharged from the first air outlet 123a. A part of the hot and humid gas is condensed into liquid, gradually falls back into the accommodation space 121 of the outer tub 120 along the first return air duct 140a, and then is discharged from the accommodation space 121 through the drain port 122; another part of the hot and humid gas becomes dry and cold gas after passing through the first condenser 170a and continues to move forward along the first return air duct 140a. Subsequently, it flows into the air inlet pipe 150 along the air exhaust end of the first return air duct 140a and the air inlet end of the air inlet pipe 150, and becomes hot air under the heating action of the heating component 160. The hot air flows into the washing cavity 131 through the air outlet end of the air inlet pipe 150 and the air inlet of the outer tub 120 to dry the clothes in the washing cavity 131.

[0084] In some embodiments of the present application, please refer to Figure 4 As shown, the washing machine 100 may further include a second condenser 170b. The second condenser 170b may adopt an air-cooled or water-cooled structure. The second condenser 170b may be detachably disposed in the second return air duct 140b. The cross-sectional area of the second condenser 170b may be the same as that of the second return air duct 140b to prevent the leakage of hot and humid gas from the gap between the second condenser 170b and the second return air duct 140b and ensure the condensation effect on the hot and humid gas. The second condenser 170b can condense the hot and humid gas discharged from the second air outlet 123b. A part of the hot and humid gas is condensed into liquid, gradually falls back into the accommodation space 121 of the outer tub 120 along the second return air duct 140b, and then is discharged from the accommodation space 121 through the drain port 122; another part of the hot and humid gas becomes dry and cold gas after passing through the second condenser 170b and continues to move forward along the second return air duct 140b. Subsequently, it flows into the air inlet pipe 150 along the air exhaust end of the second return air duct 140b and the air inlet end of the air inlet pipe 150, and becomes hot air under the heating action of the heating component 160. The hot air flows into the washing cavity 131 through the air outlet end of the air inlet pipe 150 and the air inlet of the outer tub 120 to dry the clothes in the washing cavity 131.

[0085] In some embodiments of the present application, the dry and cold gas in the first return air duct 140a and the dry and cold gas in the second return air duct 140b converge and flow into the air inlet pipe 150.

[0086] In some embodiments of the present application, both the first return air duct 140a and the second return air duct 140b may have the same structure or different structures. To improve the assembly convenience and save costs, the first return air duct 140a and the second return air duct 140b have the same structure, size, height, and thickness.

[0087] In some embodiments of the present application, please refer to Figure 4 As shown, the first return air duct 140a may include a first air duct 141, which extends away from the outer tub 120. One end of the first air duct 141 is connected to the first air outlet 123a. The first air duct 141 may be detachably connected to the first air outlet 123a to facilitate cleaning of impurities in the first return air duct 140a or the first air outlet 123a and prevent blockage.

[0088] In some embodiments of the present application, please refer to Figure 4 As shown, the first return air duct 140a may further include a second air duct 142, which extends upward. One end of the second air duct 142 is connected to the end of the first air duct 141 away from the first air outlet 123a. The second air duct 142 and the first air duct 141 may be integrally formed to facilitate assembly.

[0089] In some embodiments of the present application, please refer to Figure 4 As shown, the first return air duct 140a may further include a third air duct 143. One end of the third air duct 143 is connected to the other end of the second air duct 142, and the third air duct 143 is located at the top of the housing 110.

[0090] In some embodiments of the present application, please refer to Figure 4 As shown, the first condenser 170a may be disposed at the end of the second air duct 142 close to the third air duct 143, that is, the first condenser 170a may be disposed at the connection between the second air duct 142 and the third air duct 143. Designing the position of the first condenser 170a closer to the top of the housing 110 can extend the flow path of the humid and hot gas in the first return air duct 140a. The humid and hot gas can be partially condensed when flowing in the first return air duct 140a, so that the temperature of the humid and hot gas when reaching the first condenser 170a is lower than the temperature of the humid and hot gas at the first air outlet 123a. This can reduce the power of the first condenser 170a and further reduce the overall drying cost.

[0091] In some embodiments of the present application, please refer to Figure 4 or Figure 7As shown, this first condenser 170a can be disposed on the side of the second air duct 142 of the first return air duct 140a close to the third air duct 143, that is, it can be disposed in the second air duct 142 close to the connection between the second air duct 142 and the third air duct 143, so as to extend the flow path of the humid and hot gas in the first return air duct 140a, reduce the condensation power of the first condenser 170a, and thus reduce the overall drying cost.

[0092] In some embodiments of the present application, in order to facilitate the assembly of this first condenser 170a, the third air duct 143 and the second air duct 142 can be detachably connected. After the assembly of this first condenser 170a, the second air duct 142 and the third air duct 143 are hermetically spliced to prevent gas leakage.

[0093] In some embodiments of the present application, please refer to Figure 4 As shown, this second return air duct 140b can include a fourth air duct 144. The fourth air duct 144 extends toward the side away from the outer tub 120. One end of the fourth air duct 144 is connected to the second air discharge port 123b. This fourth air duct 144 can be detachably connected to the second air discharge port 123b to facilitate the cleaning of impurities in the second return air duct 140b or the second air discharge port 123b and prevent blockage.

[0094] In some embodiments of the present application, please refer to Figure 4 As shown, this second return air duct 140b can further include a fifth air duct 145. The fifth air duct 145 extends upward. One end of the fifth air duct 145 is communicated with the end of the fourth air duct 144 away from the second air discharge port 123b. The fifth air duct 145 and the fourth air duct 144 can be integrally formed to facilitate assembly.

[0095] In some embodiments of the present application, please refer to Figure 4 As shown, this second return air duct 140b can further include a sixth air duct 146. One end of the sixth air duct 146 is communicated with the other end of the fifth air duct 145. The sixth air duct 146 is located at the top of the housing 110.

[0096] In some embodiments of the present application, please refer to Figure 4As shown, the second condenser 170b can be disposed at one end of the fifth air duct 145 close to the sixth air duct 146, that is, the second condenser 170b can be disposed at the connection of the fifth air duct 145 and the sixth air duct 146. Designing the position of the second condenser 170b closer to the top of the housing 110 can extend the flow path of the humid and hot gas in the second return air duct 140b. The humid and hot gas can be partially condensed when flowing in the second return air duct 140b, so that the temperature of the humid and hot gas when reaching the second condenser 170b is lower than the temperature of the humid and hot gas at the second air outlet 123b. This can reduce the power of the second condenser 170b, and further reduce the overall drying cost.

[0097] In some embodiments of the present application, please refer to Figure 4 or Figure 8 As shown, this second condenser 170b can be disposed on the side of the fifth air duct 145 of the second return air duct 140b close to the sixth air duct 146, that is, it can be disposed in the fifth air duct 145 close to the connection of the fifth air duct 145 and the sixth air duct 146, so as to extend the flow path of the humid and hot gas in the second return air duct 140b, reduce the condensation power of the second condenser 170b, and further reduce the overall drying cost.

[0098] In some embodiments of the present application, in order to facilitate the assembly of this second condenser 170b, the sixth air duct 146 and the fifth air duct 145 can be detachably connected. After assembling this second condenser 170b, the fifth air duct 145 and the sixth air duct 146 are hermetically spliced to prevent gas leakage.

[0099] In some embodiments of the present application, a first filter screen can be provided at the connection of the first air duct 141 and the first air outlet 123a. This first filter screen can filter impurities with a diameter greater than 1 mm, so as to prevent the impurities from flowing into the first return air duct 140a and blocking the first return air duct 140a, and to prevent the impurities from flowing into the first condenser 170a and causing the condensation effect of the first condenser 170a to deteriorate.

[0100] In some embodiments of the present application, a second filter screen can be provided at the connection of the fourth air duct 144 and the second air outlet 123b. This second filter screen can filter impurities with a diameter greater than 1 mm, so as to prevent the impurities from flowing into the second return air duct 140b and blocking the second return air duct 140b, and to prevent the impurities from flowing into the second condenser 170b and causing the condensation effect of the second condenser 170b to deteriorate.

[0101] In some embodiments of the present application, a first valve can be provided in the third air duct 143, and the first valve can control the on-off of the third air duct 143.

[0102] In some embodiments of the present application, a second valve may be provided in the sixth air duct 146, and the second valve may control the on / off of the sixth air duct 146.

[0103] The flow path of the gas can be selected through the first valve and the second valve. For example, when only one of the return air ducts on one side needs to be opened, one of the first valve or the second valve is closed and the other is opened, and the gas can flow into the air inlet duct 150 from the opened return air duct.

[0104] It can be understood that the first return air duct 140a and the second return air duct 140b may not adopt the above structure, and other types of structures may also be adopted, as long as the humid and hot gas in the washing chamber 131 can be introduced into the air inlet duct 150.

[0105] In some embodiments of the present application, the side of the housing 110 facing the user is the front side, and the side facing away from the user is the rear side. The first return air duct 140a, the second return air duct 140b, the air inlet duct 150, and the heating component 160 are provided at a position of the housing 110 close to the rear side to increase the position on the front side of the housing 110. The first return air duct 140a, the second return air duct 140b, the air inlet duct 150, and the heating component 160 are designed at a position of the housing 110 close to the rear side, which will not affect the opening and closing of the door cover.

[0106] In some embodiments of the present application, the air inlet duct 150 can be assembled with the outer tub 120 at a position close to the rear side, and the air outlet end of the air inlet duct 150 leads the drying air into the outer tub 120 from top to bottom.

[0107] In some embodiments of the present application, please refer to Figure 6 As shown, the heating component 160 may include a fan 161. The fan 161 can be used to drive the dry and cold gas in the first return air duct 140a and the second return air duct 140b into the air inlet duct 150, and can blow the dry and cold gas towards the air outlet end of the air inlet duct 150.

[0108] In some embodiments of the present application, please refer to Figure 6 As shown, the heating component 160 may further include a heating element 162. The heating element 162 may be provided on a side of the fan 161 close to the air outlet end of the air inlet duct 150. The dry and cold gas brought in by the fan 161 enters the heating element 162 for heating. After heating, the dry and cold gas becomes dry and hot gas. The dry and hot gas is ejected from the air outlet end of the air inlet duct 150 towards the air inlet of the outer tub 120 and enters the washing chamber 131 of the inner tub 130 to dry the clothes.

[0109] It can be understood that after the clothes are dried, the dry and hot gas becomes wet and hot gas because it takes away the moisture on the clothes. Subsequently, it enters the first return air duct 140a and the second return air duct 140b through the first row of air vents 123a and the second row of air vents 123b, and is condensed under the condensation action of the first condenser 170a and the second condenser 170b. A part of the wet and hot gas becomes liquid and flows back to the accommodation space 121 along the first return air duct 140a and the second return air duct 140b, and is discharged through the drain port 122. Another part of the wet and hot gas becomes dry and cold gas, and enters the air inlet duct 150 along the first return air duct 140a and the second return air duct 140b. Subsequently, the dry and cold gas is turned into hot air under the action of the fan 161 and the heating element 162, and the hot air flows through the air outlet end of the air inlet duct 150 and the air inlet of the outer tub 120 into the washing cavity 131 of the inner tub 130 to dry the clothes. Through the above cycle, the moisture on the clothes is continuously removed.

[0110] In some embodiments of the present application, the heating element 162 can be an electric heater, and the electric heater can heat the dry and cold gas to become dry and hot air.

[0111] It should be noted that when the heating element 162 is arranged in front of the fan 161, the drying air can be fully heated and the air volume can also be increased. In addition, when the heating element 162 is arranged in front of the fan 161, when the heating element 162 stops heating, the fan 161 can cool the heating element 162 to reduce the temperature of the heating element 162 and avoid problems such as scalding caused by accidental contact.

[0112] In some embodiments of the present application, please refer to Figure 9 and Figure 10 As shown, the washing machine 100 can also include a pulsator 180. The pulsator 180 can be rotatably arranged in the washing cavity 131, and the pulsator 180 can drive the clothes in the washing cavity 131 to be cleaned. The pulsator 180 can also work during the drying process of the clothes. Turning the clothes can also improve the drying efficiency of the clothes. During the turning and drying process of the pulsator 180, the winding degree and folding degree of the clothes can also be reduced, which is beneficial to improving the flatness of the clothes after drying. Since the drying efficiency of the clothes is improved, the drying temperature of the clothes can be reduced, that is, the heating efficiency of the heating element 162 is reduced, and the damage to the clothes caused by high temperature is reduced.

[0113] In some embodiments of the present application, please refer to Figure 9 and Figure 10As shown, the washing machine 100 may further include a drive assembly 190. The drive assembly 190 may be disposed within the housing 110. The drive assembly 190 may be rotationally connected to the inner tub 130 and the agitator 180. The drive assembly 190 may drive the inner tub 130 and the agitator 180 to rotate. The inner tub 130 and the agitator 180 may rotate in the same direction or in different directions.

[0114] The washing machine 100 of the solution of the present application can implement programs such as single washing, single drying, and washing and drying in one, and can achieve effects such as washing and drying of clothes. By using the first return air duct 140a and the second return air duct 140b located on opposite sides of the outer tub 120, the contact area between the drying air and the wet clothes can be increased, the evaporation of moisture on the wet clothes can be accelerated, and the drying efficiency can be improved.

[0115] In addition, during the drying process, the agitator 180 can be used to turn the clothes to improve the drying efficiency of the clothes. During the turning process, the winding degree and folding degree of the clothes can be reduced, which is beneficial to improving the flatness of the clothes after drying. Since the efficiency of drying clothes is improved, the drying temperature can be appropriately reduced to reduce the damage caused by high temperature to the clothes.
