-
In related technologies, for a dual-drum washing machine with a standard cabinet, it includes a first drum and a second drum. The second drum is arranged above the first drum. Due to the design of the standard cabinet, where the cabinet dimensions are fixed, the height of the second drum is typically greater than or equal to the height of a conventional detergent dispenser. Conventional manual dispensing relies on water flow utilizing gravity to flush laundry detergent from the dispenser into the drum. This makes it impossible to manual dispense laundry detergent into the second drum using conventional manual dispensing methods.
-
To solve the above technical problems, the invention provides a washing machine. As illustrated in FIGS. 1-4, the washing machine includes: a first drum 1; a second drum 2, in which a diameter of the second drum 2 is smaller than a diameter of the first drum 1; and a door assembly 3 selectively covering an opening of the second drum 2, the door assembly 3 includes a door body 31, a protrusion 32 and a dispensing device 33, the protrusion 32 is arranged on an inside of the door body 31, the dispensing device 33 is arranged on the protrusion 32 and has a feeding port 50, a water inlet 10 and an outlet 20 being in communication with both the feeding port 50 and the water inlet 10.
-
Through the above technical solutions, in the washing machine provided by the invention, the user can put the laundry detergent into the dispensing device 33 via the feeding port 50. When the door assembly 3 closes the opening of the second drum 2, the second drum 2 can processed with washing the laundry. Since the dispensing device 33 is arranged on the protrusion 32, the outlet 20 is currently in communication with the interior of the second drum 2. When water enters the dispensing device 33 through the water inlet 10, it mixes with the laundry detergent and is flushed into the second drum 2 through the outlet 10. This enables manual dispensing of laundry detergent into the second drum 2 via the door.
-
In some implementations of the invention, as illustrated in FIGS. 2-3, the dispensing device 33 includes a mixing chamber 331. The mixing chamber 331 is connected between the water inlet 10 and the outlet 20, and it is also connected between the feeding port 50 and the outlet 20. This enables more effective mixing of the water flow with the laundry detergent, and facilitates the water flow carrying the laundry detergent to the outlet 20.
-
In some embodiments of the invention, as illustrated in FIGS. 2-4, the dispensing device 33 includes a siphon structure arranged in the mixing chamber 331. The siphon structure may include a siphon pipe 332 and a siphon cap 333. The siphon pipe 332 is communicated with the outlet 20, and the siphon cap 333 is sleeved on the siphon pipe 332 and forms a siphon passage 30 with the siphon pipe 332.
-
Through the above technical solutions, when water flow is continuously entering the mixing chamber 331, the level of the mixture in the mixing chamber 331 continuously rises. When the level of the mixture exceeds the siphon position of the siphon structure, the mixture undergoes a siphon effect and continuously flows through the siphon passage 30 to the outlet 20, and then flows into the interior of the second drum 2. This thereby enables the manual siphoning of laundry detergent into the second drum 2. Since the diameter of the second drum 2 is smaller than that of the first drum 1, the second drum 2 may be used to wash smaller-sized or lighter clothing, while the first drum 1 may be used to wash larger-sized or heavier clothing.
-
It should be noted that the principle of the siphon effect in the mixture using the siphon pipe 332 and the siphon cap 333 is well known to those skilled in the art, which will not be repeated here. The laundry detergent in the invention at least includes detergent, fabric softener, disinfectant, etc., which is not limited by the invention. The aforementioned mixture is understood as a mixture of water and laundry detergent. In some embodiments, the protrusion 32 is made of glass, which is not limited by the invention.
-
In some implementations of the invention, as illustrated in FIG. 2, the dispensing device 33 includes a feeding chamber 334. The feeding chamber 334 is connected between the feeding port 50 and the mixing chamber 331, so that the laundry detergent can enter the feeding chamber through the feeding port and then flow into the mixing chamber, which facilitate the mixing of water flow and washing solution.
-
In some embodiments of the invention, as illustrated in FIG. 2, the protrusion 32 is provided with an accommodating cavity 321. The mixing chamber 331 and the feeding chamber 334 are both arranged in the accommodating cavity 321. This arrangement utilizes the inherent space of the protrusion 32 to accommodate the mixing chamber 331 and the feeding chamber 334, which reduces the volume of the door assembly 3, and facilitates the efficient utilization of space of the washing machine.
-
In some embodiments of the invention, as illustrated in FIGS. 2-3, the dispensing device 33 includes a cover 335. A first sub-cover 3351 of the cover 335 is used for covering over the feeding chamber 334, and the first sub-cover 3351 is provided with a vent hole 40 in communication with the feeding chamber 334. The vent hole 40 enables the communication between the feeding chamber 334 and the atmosphere, which facilitates the siphon effect of the mixture through the siphon structure. The first sub-cover 3351 is provided with the aforementioned feeding port 50.
-
In some implementations, as illustrated in FIGS. 2-3, there are a plurality of vent holes 40 arranged in rows and columns. The advantage of the configuration is that it allows for a reduction in the diameter of the vent hole 40 while maintaining the same layout area. This prevents foreign objects from entering the feeding chamber 334. Furthermore, the smaller diameter of vent hole 40 also prevents components inside the feeding chamber 334 from leaking out.
-
In some implementations, the feeding chamber 334 includes a plurality of separate compartments. For example, it may include three compartments, with each compartment dedicated to dispense laundry detergent, fabric softener, and disinfectant, respectively, which is not limited in the invention.
-
In some implementations, as illustrated in FIGS. 2-3, the cover 335 may include a second sub-cover 3352. The siphon cap 333 is connected to the second sub-cover3352. This allows the siphon cap 333 to be simultaneously fitted onto the siphon pipe 332 during the installation of the second portion 3352. The second sub-cover 3352 is used for covering over the mixing chamber 331 and is provided with the water inlet 10 formed therein, facilitating the formation of the water inlet 10.
-
In some embodiments, the cover 335 is detachably connected to the protrusion 32, which facilitates the disassembly, assembly, and replacement of the cover 335. After the cover 335 is removed, the user can clean residual liquid in the feeding chamber 334 and the mixing chamber 331. In some embodiments, the cover 335 and the protrusion 32 may be clutched together. For example, one of the cover 335 and the protrusion 32 is provided with a snap, while the other is provided with a matching slot. After pressing the snap into the slot, the cover 335 is clutched with the protrusion 32. Certainly, the cover 335 and the protrusion 32 may be connected via fasteners, which is not limited by the invention.
-
In some implementations of the invention, as illustrated in FIGS. 2-4, the protrusion 32 has a first side and a second side opposite to each other in an axial direction of the door assembly 3, the first side is connected to the door body 31, and the second side is provided with the outlet 20. Since the second side is closer to the interior of the second drum 2 than the first side, this configuration further ensures that the mixture flowing out through the outlet 20 enters the interior of the second drum 2.
-
In some implementations of the invention, as illustrated in FIG. 1, the second drum 2 is arranged at the upper-right side of the first drum 1, which facilitates the user to fetch the washing inside the second drum 2. Certainly, in other implementations, the second drum 2 may also be arranged at the upper-left, lower-left or even lower-right side of the first drum 1, which is not limited by the invention.
-
In some implementations of the invention, the first drum 1 may also be configured with the aforementioned door assembly 3, which realizes manual delivery of washing solution into the first drum 1.
-
