[0002] At present, self-service shared washing machines are arranged in schools, apartments and other places. According to actual needs, this type of self-service shared washing machine provides two functions: normal temperature water washing and hot water washing to meet the needs of clothing washing. In order to realize the hot water washing function, a heating pipe is conventionally installed in the washing machine, through which the water injected into the washing machine is heated. At present, normal temperature water washing and hot water washing share a water delivery channel when filling water.

The aforementioned third channel 13 extends along the length direction of the substrate 1, and the first end of the third channel 13 forms a third assembly port 131 at the rear edge of the substrate 1, and the second end of the third channel 13 is connected to the first channel 11, and the third channel 13 is connected to the second channel 12. Through the connection of the third channel 13, the second channel 12 and the first channel 11 are connected to each other. In this embodiment, the communication position between the third channel 13 and the second channel 12 is arranged at a position close to the second assembly port 121. Through the above structural design, the first water collecting chamber 112 is directly connected to the water injection port, and the second water collecting chamber 122 is connected to the water injection port after passing through the second channel 12, the third channel 13, the first channel 11 and the first water collecting chamber 112 in sequence.

[0035] The aforementioned electric heater 2 has a designed length, and it can be inserted into the second channel 12 via the second assembly port 121, and is threadedly sealed with the second assembly port 121. The heating part of the electric heater 2 is accommodated in the second channel 12, and when water enters the second channel 12, the water can be heated. The above-mentioned electric heater 2 is a conventional component in the prior art, preferably an electric heating tube.

After opening the electromagnetic switch valve body 8 on the first water pipe 4, the second water pipe 5, and the air outlet pipe 71, the airflow blown out by the fan can be delivered to the water inlet pipe 6 through the air outlet pipe 71, then enter the first water pipe 4 or the second water pipe 5, and finally discharged from the water injection port. According to the actual structural design, a set of electric heating wires can be installed in the housing 7 between the fan and the air outlet, so that the airflow discharged through the air outlet is a hot airflow.

[0039] It should be noted that the electromagnetic switch valve body 8 on the first water delivery pipe 4 and the electromagnetic switch valve body 8 on the second water delivery pipe 5 can be opened in one group or all of them. In addition, the plug 3 in the third assembly port 131 can be removed so that part of the airflow blown out by the fan can be discharged through the third assembly port 131.

[0040] In the specific structural design of this embodiment, the first water collecting chamber 112 forms an open end on the front side of the substrate 1. The front side of the substrate 1 is the surface facing the outside of the washing machine, and the back side of the substrate 1 is the surface facing the inside of the washing machine. A first flange 41 is installed at the end of the first water supply pipe 4.

By flipping the cover body 9, the base plate 1 can be driven to move and the interior of the washing machine can be opened and closed. The base plate 1 has a wiring side facing the hinged position 91. A wiring groove 14 is processed on the edge of the base plate 1, and the wiring groove 14 extends along the edge of the base plate 1 to the wiring side and is at least connected to the second assembly port 121. In this embodiment, the wiring groove 14 is also connected to the third assembly port 131. The cable of the electric heater 2 can be hidden and accommodated in the wiring groove 14, and the cables of the aforementioned electromagnetic switch valve bodies 8 and the cables of the fan can all be hidden and accommodated in the wiring groove 14. Through the above-mentioned structural design, the overall wiring is neat and reliable, so as to prevent the cables of the electric heater 2, the electromagnetic switch valve body 8, the fan, etc. from being pulled apart during the opening and closing process of the cover body 9 of the washing machine.

[0043] When used specifically, during the water injection process of conventional water washing, the electromagnetic switch valve body 8 on the first channel 11 is opened, and normal temperature water enters the first water collecting chamber 112 through the water inlet pipe 6 and the first channel 11, and then is discharged from the water injection port. During the water injection process of hot water washing, the electromagnetic switch valve body 8 on the second channel 12 is opened, and normal temperature water enters the first water collecting chamber 112 through the water inlet pipe 6, the second water collecting chamber 122, the second channel 12, the third channel 13, and the first channel 11 in sequence, and then is discharged from the water injection port. During the water injection process, the normal temperature water is heated into hot water by the electric heater 2. The combination of the above methods can separate the water injection processes of normal temperature water washing and hot water washing from each other, so as to slow down the accumulation speed of scale on the electric heater 2, so as to effectively extend the service life of the electric heater 2, and has strong practicality.

[0044] After washing is completed, open the electromagnetic switch valve body 8 on the air outlet pipe 71 and the electromagnetic switch valve body 8 on the second channel 12, and the air flow blown out by the fan enters the first water collecting chamber 112 through the water inlet pipe 6, the second water collecting chamber 122, the second channel 12, the third channel 13, and the first channel 11 in sequence, and is then discharged from the water inlet to blow out the residual water vapor in the above-mentioned channels, so that the above-mentioned channels remain dry, effectively reduce the growth of bacteria, and effectively meet the hygiene requirements of self-service shared washing machines.
