[0028] The utility model will be described further in detail below with reference to the drawings.

[0029] like Figures 1-8 As shown, the water tank type cleaning machine of this embodiment includes a water tank 1 and a door 2 that can be flipped and is located at the top opening of the water tank 1. The door 2 includes a main body 21 and a glass plate 22. The main body 21 forms a accommodating cavity 211 with an open top. An electromagnetic heating module 3 is provided in the accommodating cavity 211. The glass plate 22 is located on the top of the main body 21 and closes the accommodating cavity 211. A temperature detector 6 that can detect the temperature inside the accommodating cavity 211 and an air extraction component 7 that exhausts the hot air in the accommodating cavity 211 to the outside of the accommodating cavity 211 are also provided in the accommodating cavity 211. The temperature detector 6 and the air extraction component 7 are electrically connected.

[0030] A temperature detector 6 and an air extraction component 7 are installed in the accommodating cavity 211 to exhaust the hot air in the accommodating cavity 211 to the outside of the accommodating cavity 211. When the temperature inside the door body 2 is detected to be higher than the set value, the air extraction component 7 is activated to exhaust the hot air in the door body 2, thereby controlling the temperature inside the door body 2 within a certain range and avoiding damage to the switch component installed in the door body 2 due to high temperature.

[0031] The exhaust assembly 7 includes an air duct 71 and a fan 72. An exhaust port 23 is provided on the side wall of the door 2. The inlet end of the air duct 71 is connected to the fan 72, and the outlet end of the air duct 71 is connected to the exhaust port 23. The air inlet of the fan 72 is located near the electromagnetic heating module 3. This structure facilitates the timely exhaust of hot air from inside the door 2.

[0032] The air duct 71 is equipped with a first outlet 701 and a second outlet 702. The first outlet 701 is arranged corresponding to the exhaust port 23, and the second outlet 702 is connected to the inner cavity of the sink 1. It also includes an adjustment structure 8 that can switch the connection between the fan 72 and the first outlet 701 and the second outlet 702. Since the sink-type washer usually involves at least one hot air step in the dishwashing process, the above structure draws the hot air from the door 2 into the inner cavity of the sink 1 when dishwashing is required, which helps to improve heat utilization and reduce energy consumption.

[0033] The air duct 71 includes a first section 711 extending laterally, with a first outlet 701 at its outer end. The inner end of the first section 711 is bent downward to form a second section 712 arranged parallel to the first section 711. The first section 711, the second section 712, and their junction together form a U-shaped cavity 710. A third section 713, extending downward and sequentially connecting the end of the second section 712 and the inner cavity of the water tank 1, is connected to the bottom of the first section 711. A second outlet 702 is provided at the lower end of the third section 713. At least a portion of the adjustment structure 8 is movably disposed within the U-shaped cavity 710. Using the above structure, and utilizing the U-shape of the air duct 71 to set the adjustment structure 8, the overall structure is compact, and the operation is stable and reliable.

[0034] The adjusting structure 8 comprises an elastic member 81, a partition plate 82, an air bag 83 and a ball 84. The partition plate 82 is movably arranged in the corresponding first section 711 of the U-shaped cavity 710. The air bag 83 is connected to the end of the U-shaped cavity 710 near the third section 713 in an extendable and retractable manner and has an opening communicating with the U-shaped cavity 710. The elastic member 81 is arranged in the first section 711 of the U-shaped cavity 710 and always keeps the partition plate 82 away from the closed end of the U-shaped cavity 710. The ball 84 is movably arranged in the corresponding first section 711 above the third section 713 and moves towards the partition plate 82 to drive the partition plate 82 to move towards the closed end of the U-shaped cavity 710 or moves in the opposite direction to cancel the force acting on the partition plate 82. With the above structure, the switching of the opening and closing of the first outlet 701 and the second outlet 702 can be realized by the compression of the air in the U-shaped cavity 710 and the cooperation with the air bag 83.

[0035] An electromagnetic module 85 corresponding to the arrangement of the elastic member 81 and the ball 84 is arranged in the accommodating cavity 211. In the energized state, the electromagnetic module 85 is used to attract the ball 84 to drive the baffle to move towards the closed end of the U-shaped cavity 710, press the gas in the U-shaped cavity 710 into the air bag 83 to expand the air bag 83 and cut off the third section 713. In the de-energized state, the electromagnetic module 85 is used to repel the ball 84 to cancel the force acting on the partition plate 82 and cut off the first section 711 downstream of the third section 713, and the air bag 83 is retracted to communicate the third section 713. The inner diameter of the third section 713 is smaller than the diameter of the ball 84. The first section 711 is provided with a limiting ring 715 capable of cooperating with the ball 84 to cut off the first section 711. With the above structure, when the dishwasher is not needed to be used and only the hot air in the door body 2 needs to be discharged, the electromagnetic module 85 is energized to generate an attractive force on the ball 84. The ball 84 drives the partition plate 82 to compress the spring. The gas in the U-shaped cavity 710 is compressed into the air bag 83. The air bag 83 is expanded and pops into the third section 713 to cut off the third section 713. At this time, not only the hot air sucked by the fan 72 is prevented from entering the sink 1 through the third section 713, but also the moisture in the sink 1 is prevented from entering the door body 2 through the air guide pipe 71. The middle part of the first section 711 is connected with the fan 72 through the fourth section 714. The fourth section 714 is arranged corresponding to the top of the third section 713.

[0036] The side edge of the door body 2 is also provided with a stop block 9 capable of opening or closing the air outlet 23. The stop block 9 is movably constrained in the door body 2 perpendicular to the air outlet 23. The inner side wall of the stop block 9 is a slope 91 arranged corresponding to the outlet end of the air guide pipe 71. The end of the stop block 9 is provided with a spring 92 capable of driving the stop block 9 to move laterally to close the air outlet 23 or to move in the opposite direction to open the air outlet 23 in the air outlet pushing slope state. With such a structure, in the non-air exhaust state, external moisture can be prevented from entering the door body 2, and in the air exhaust state, the stop block 9 can be automatically pushed open without affecting the air exhaust.

[0037] The electromagnetic heating module 3 is arranged at the central part of the accommodating cavity 211 and comprises an inductor coil 31 and magnets 32. The inductor coil 31 is disc-shaped, and the magnets 32 are arranged radially on the inductor coil 31. The above structure is adopted to generate heat by electromagnetic induction in the energized state.

[0038] The inductor coil 31 comprises an outer ring 311 arranged in the circumferential direction and a plurality of coil arms 312 arranged radially in the outer ring 311. Each coil arm 312 is connected to a shaped inner ring 313 near the center of the coil. The magnets 32 comprise a first part 321 extending along the length of the coil arm 312 at the bottom of the coil arm 312. The first part 321 is bent upward near the inner ring 313 to form a second part 322 passing through the inner ring 313. The first part 321 is bent upward near the outer ring 311 to form a third part 323 passing through the outer ring 311.

[0039] The inductor coil 31 comprises an upper base body 301 and a lower base body 302 stacked vertically. The outer ring 311 of the upper base body 301 is an open ring structure, and the outer ring 311 of the lower base body 302 is a closed ring structure. The diameter of the outer ring 311 of the lower base body 302 is greater than that of the upper base body 301. The outer ring 311 of the lower base body 302 is provided with a through-knocking 314. Correspondingly, the lower surface of the outer ring 311 of the upper base body 301 is provided with a clamping leg 315 extending downward and matched with the knocking 314.

[0040] The inner ring 313 is provided with a first opening 316 passing through vertically and for the second part 322 to pass through. The outer ring 311 is provided with a second opening 317 passing through vertically and for the third part 323 to pass through. In the assembled state, the third part 323 is arranged close to the outer edge of the outer ring 311 of the upper base body 301.

[0041] The above electromagnetic heating structure is convenient for production and assembly. The outer ring 311 of the lower base body 302 can be fixed on the bottom wall of the accommodating cavity 211 by screws. The heating effect is reliable and stable.

[0042] In this embodiment, the accommodating cavity is directly formed in the main body of the door body, and the electromagnetic heating module is arranged in the accommodating cavity. The glass plate is placed flat on the top of the accommodating cavity, which not only seals the accommodating cavity but also serves as a heat transfer member for supporting the pot. The overall structure is simple and compact, and convenient for assembly. Meanwhile, a temperature detector and an air exhaust assembly for exhausting the hot air in the accommodating cavity are arranged in the accommodating cavity. When the temperature in the door body is detected to be higher than the set value, the air exhaust assembly is started to exhaust the hot air in the door body, so as to control the temperature in the door body within a certain range and avoid damage to the switch assembly arranged in the door body caused by high temperature, thereby improving the operation reliability of the sink cleaning machine.
