Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of clothes dryers, and particularly relates to a clothes dryer water box assembly and a clothes dryer with the same. BACKGROUND

[0002] A clothes dryer is a cleaning household appliance that uses electric heating to evaporate and dry the moisture in washed clothes. The clothes dryer mainly comprises a cabinet, a control panel, a drum, a motor, a fan, a heater, a condenser, a water tank, a water pump and a water box. The drum is arranged in the cabinet, clothes are placed in the drum, and the drum can rotate under the drive of the motor. The fan promotes the circulation of air, which is heated by the heater. The circulating air becomes hot air, which is blown into the drum from below the door body to dry the clothes. The circulating air carrying the moisture in the wet clothes from the drum becomes hot and humid air, which flows out from the air duct below the door body, is condensed by the condenser, and becomes dry and low-temperature air for further circulation. The condensed water vapor from the condenser becomes liquid and is stored in the water tank. The water in the water tank can be pumped out by the water pump and into the water box.

[0003] The water box of the clothes dryer is generally arranged obliquely above the drum, and the water box is pulled out and located in the water box slot. When the water in the water box is full, the user needs to manually pull out the water box, pour out the water, and then install it back to the original position. The water box is slidably connected to the water box slot, and the water box slot is fixed to the cabinet of the clothes dryer.

[0004] The clothes dryer generally has a spraying structure for humidifying, wrinkle removing, sterilizing and other treatments on the clothes, so that the dried clothes are more flat. The spraying structure is usually installed on the front support of the drum and sprays towards the inside of the drum. In order to make full use of the condensed water, the spraying structure can directly take water from the water box slot. The water inlet waterway collects most of the condensed water into the water box, and a small amount of the condensed water is collected into the water box slot for use by the spraying structure. For example, Chinese patent 201911181275.9 discloses a water box slot for a clothes dryer, which comprises a water box slot body, a water supply tank assembly is arranged on the water box slot body, a water inlet and a water outlet are arranged on the water supply tank assembly, the water inlet is used for communicating with the water circulation pipeline of the clothes dryer and supplying water to the water supply tank assembly, and the water outlet is used for communicating with the spraying device of the clothes dryer and supplying water in the water supply tank assembly to the spraying device.

[0005] However, at present, the water box of the clothes dryer can be pulled out, and the condensed water in the water box is poured out. However, the condensed water in the water box slot for supplying the spraying structure is automatically replenished after use, so that there is always a full storage amount of condensed water in the water box slot. The long-term storage of a large amount of condensed water causes the condensed water in the water box slot to deteriorate, easily accumulate dirt, produce odor, etc., which is not conducive to the cleaning of the whole machine and the health of consumers.

[0051] Referring to Figures 1-10 , the water box assembly 100 of the drying machine comprises a water box slot 10, a water box 20 and a distribution module 30. The water box 20 is slidably pulled out in the water box slot 10 and is used for storing condensed water. The water box slot 10 is provided with a spraying water slot 11 for supplying water to a spraying structure. The distribution module 30 is arranged on the water box 20 and has a first flow path in communication with the water box 20, a second flow path in communication with the spraying water slot 11 and an adjusting structure 31 for adjusting the flow of the second flow path. A water inlet pipe is connected with the distribution module 30. The condensed water in a water storage tank of the drying machine is transported to the distribution module 30 through the water inlet pipe. The condensed water flows into the water box 20 through the first flow path and flows into the water box slot 10 through the second flow path. The adjusting structure 31 can adjust the flow of the second flow path. The flow can be adjusted between maximum and zero. The flow can be maximum or zero. When the flow is zero, the second flow path is closed. Thus, the flow direction of the condensed water can be controlled by arranging the distribution module 30. The flow of the second flow path can be adjusted according to the needs of the spraying structure.

[0052] In this embodiment, the condensed water can flow into the water box 20 through the first flow path and can flow into the spraying water slot 11 through the second flow path by arranging the distribution module 30. The water supply to the spraying water slot 11 can be controlled by opening and closing the second flow path. The condensed water can flow into the spraying water slot 11 during spraying. The long-term retention of a large amount of condensed water in the spraying water slot 11 is avoided. The clean and clean condensed water can be provided. The condensed water can be supplied on demand according to the needs of the spraying. A large amount of condensed water is avoided after the spraying is finished. The clean and sanitary state is further ensured.

[0053] The adjusting structure 31 can control the opening and closing of the second flow path and can control the flow of the second flow path. For the above functions of the adjusting structure 31, various forms can be adopted. In this embodiment, the adjusting structure 31 is rotatably arranged. The above functions of opening, closing and adjusting the flow are realized by rotating.

[0054] Specifically, the adjusting structure 31 is provided with a cover part 311 for closing the second flow path. An opening 3112 for realizing the opening of the second flow path is arranged in the cover part 311. The position of the opening 3112 is adjusted by rotating the adjusting structure 31. The flow of the second flow path is adjusted.

[0055] In other embodiments, the adjusting structure 31 can control the flow of the second flow path by other moving manners, such as translation, etc. Or the control of the flow of the second flow path can be realized by the movement of the part of the adjusting structure 31, such as only the rotation or translation of the cover part 311, or the movable closing plate for sealing the through hole 3112, etc.

[0056] Referring to Figure 2 As shown, the flow distribution module 30 has a flow distribution pipe 32 fixed on the water box 20, the flow distribution pipe 32 has a second branch pipe 322 in communication with the spray water tank 11, the cover part 311 covers the second branch pipe 322, the through hole 3112 can be in communication with the second branch pipe 322, and the second branch pipe 322 has an upper opening. By rotating the adjusting structure 31, the through hole 3112 is rotated relative to the second branch pipe 322. When the through hole 3112 is entirely or partially located directly above the first upper opening of the second branch pipe 322, the water flow passing through the through hole 3112 entirely or partially flows into the second branch pipe 322. By rotating the adjusting structure 31, the area of the through hole 3112 located directly above the first upper opening of the second branch pipe 322 is adjusted, and the flow of the condensed water flowing into the second branch pipe 322 can be adjusted. When the through hole 3112 is not located directly above the first upper opening of the second branch pipe 322, the water flow passing through the through hole 3112 does not flow into the second branch pipe 322, that is, the second flow path is in a closed state, and water is not supplied to the spray water tank 11. It is preferred that the through hole is elliptical, and the short axis of the elliptical shape is in the radial direction of the cover part 311, which is beneficial to improve the accuracy of the flow adjustment of the second flow path.

[0057] Referring to Figures 3-6 As shown, the flow distribution pipe 32 further has a first branch pipe 321 arranged adjacent to the second branch pipe 322, the first branch pipe 321 has a water passing hole 3211 in communication with the water box 20, that is, in communication with the cavity of the water box 20, the through hole 3112 can be in communication with the first branch pipe 321, and the first branch pipe 321 has a second upper opening. By rotating the adjusting structure 31, the through hole 3112 is rotated, and the through hole 3112 can be located directly above the first branch pipe 321, or directly above the second branch pipe 322, or partially located directly above the first branch pipe 321 and / or partially located directly above the second branch pipe 322. The condensed water passing through the through hole 3112 can flow into the water box 20 through the first branch pipe 321, or flow into the spray water tank 11 through the second branch pipe 322. The second flow path is the condensed water flow path formed by the through hole 3112 and the second branch pipe 322.

[0058] The shunt pipe 32 also has a communication cavity 323 in communication with the second branch pipe 322, the communication cavity 323 is located below the second branch pipe 322, the cross-sectional area of the communication cavity 323 is larger than that of the second branch pipe 322, and the cross-section here refers to the radial cross-section. By arranging the communication cavity 323, the water flow in the second branch pipe 322 flows into the communication cavity 323 with a larger space, which is conducive to the role of flow stabilization. Preferably, the communication cavity 323 is arranged as a frustum-shaped cavity with a large lower part and a small upper part. The second flow path is the condensate water flow path formed by the through hole 3112, the second branch pipe 322, and the communication cavity 323.

[0059] Referring to Figures 7-9 As shown, the cover part 311 has a circular cover plate 3111, a limiting edge 3113 arranged downward along the edge of the cover plate 3111, the limiting edge 3113 is located outside the upper end of the shunt pipe 32, and the outer diameter of the shunt pipe 32 is matched with the inner diameter of the limiting edge 3113. The shunt pipe 32 and the cover part 311 are coaxially arranged. When the adjusting structure 31 rotates, the limiting edge 3113 cooperates with the shunt pipe 32 to limit the rotation, so that the adjusting structure 31 rotates around the shaft, which is conducive to ensuring the stability of the rotation and avoiding deviation.

[0060] A limiting structure is arranged between the cover part 311 and the shunt pipe 32 to limit the rotatable range of the adjusting structure 31, so that the through hole 3112 is in communication with the first branch pipe 321, or the through hole 3112 is in communication with the second branch pipe 322, or the through hole 3112 is in communication with the first branch pipe 321 and the second branch pipe 322 at the same time. By arranging the limiting structure, the adjusting structure 31 can only rotate within a certain angle range, so that the through hole 3112 is in a communication state, and the water flow can pass through the through hole 3112, avoiding the through hole 3112 being closed; which is conducive to ensuring the smoothness of the water flow passing through the through hole 3112.

[0061] The limiting structure has two limiting partitions 324 arranged at intervals in the radial direction of the shunt pipe 32, and a limiting block 3114 extending downward is arranged on the cover part 311; when the adjusting structure 31 rotates, the limiting block 3114 moves between the two limiting partitions 324. By arranging the limiting partitions 324 and the limiting block 3114, the rotation range of the adjusting structure 31 is limited. Preferably, the limiting block 3114 has two limiting edges extending in the radial direction of the cover plate 3111, and the two limiting edges are matched with the two limiting partitions 324, respectively.

[0062] The adjusting structure 31 is a circular structure, and the adjusting structure 31 further has an outer ring portion 312 sleeved outside the cover portion 311. A plurality of water inlets 313 in communication with the water box 20 are arranged between the outer ring portion 312 and the cover portion 311. The water flowing from the water inlet pipe opens the second flow path to guide the condensed water into the spraying water tank 11 only when the spraying structure is opened, otherwise the condensed water flows into the water box 20 through the first flow path. By arranging the plurality of water inlets 313 surrounding the outside of the cover portion 311, the amount of condensed water flowing into the water box 20 is ensured; the condensed water flowing through the water inlets 313 directly falls into the water box 20. The first flow path has two flow paths through the adjusting structure 31, and the first flow path includes the flow path of the plurality of water inlets 313, the flow path formed by the through hole 3112 and the first branch pipe 321.

[0063] The water box 20 further includes a box body 21 and a water box cover 22 arranged on the box body 21. The water box cover 22 is provided with a mounting hole 221, and the adjusting structure 31 is rotatably arranged in the mounting hole 221. The arrangement of the water box cover 22 is beneficial to increasing the sealing property of the water box 20 and facilitating the mounting and fixing of the adjusting structure 31.

[0064] The mounting and cooperation structure between the adjusting structure 31 and the mounting hole 221 is provided with a mounting edge 222 extending downward along the edge of the mounting hole 221. The outer side surface of the adjusting structure 31 is provided with an upper turning edge 3121 and a lower turning edge 3122 extending outward. The outer side surface of the outer ring portion 312, the upper turning edge 3121 and the lower turning edge 3122 surround to form a mounting groove 3123 for accommodating the mounting edge 222, which is beneficial to the stability of the adjusting structure 31 after mounting and has a rotation limiting effect. The edge of the mounting hole 221 is provided with a slot 223 matched with the upper turning edge 3121, and the upper turning edge 3121 is located in the slot 223.

[0065] Referring to Figure 10 As shown in the figure, the structure of the water box groove 10 is illustrated. The water box groove 10 is provided with a water receiving groove 12 located below the second flow path, a drainage flow channel 13 connected with the water receiving groove 12, and a filter groove 14 arranged between the drainage flow channel 13 and the spraying water tank 11. The water receiving groove 12 is matched with the lower end surface of the communication cavity 323, and the depth of the water receiving groove 12 is the same as the depth of the drainage flow channel 13. The condensed water flowing from the communication cavity 323 falls into the water receiving groove 12, and then reaches the filter groove 14 through the drainage flow channel 13, and flows into the spraying water tank 11 after being filtered. The spraying liquid outlet pipe is arranged at the bottom of the spraying water tank 11.

[0066] The water box groove 10 is further provided with an overflow groove 15 in communication with the spraying water tank 11, and the overflow groove 15 is provided with an overflow port at the bottom. The depth of the overflow groove 15 is less than the depth of the spraying water tank 11.

[0067] The control method of the water box assembly of the clothes dryer in the embodiment is that the second flow path is in a normally closed state, when the spraying function of the clothes dryer is started, the adjusting structure 31 is rotated to open the second flow path, so that the condensed water flows into the spraying water tank 11. It ensures that the condensed water for spraying is supplied when needed, and is not supplied when not needed, avoiding long-term retention of condensed water in the spraying water tank 11.

[0068] Specifically, S10. Start the spraying function of the clothes dryer.

[0069] S20. The adjusting structure 31 is rotated to open the second flow path.

[0070] The adjusting structure 31 is rotated, so that all or part of the through port 3112 is located directly above the first upper opening of the second branch pipe 322, so that the water flow through the through port 3112 all or part flows into the second branch pipe 322, and then falls into the water receiving tank 12 of the water box tank 10 through the communication cavity 323, and then reaches the filter tank 14 through the drainage flow channel 13, and then flows into the spraying water tank 11 after filtration.

[0071] For the adjustment of the flow of the second flow path, the flow of the second flow path can be adjusted according to the selected intensity level of the spraying function; the flow of the condensed water through the second flow path is adjusted by the angle of the rotating adjusting structure 31. Specifically, the adjusting structure 31 is rotated, and the area of the through port 3112 located directly above the first upper opening of the second branch pipe 322 can adjust the flow of the condensed water flowing into the second branch pipe 322.
