Through-type dishwashers and long-haul dishwashers usually have high washing efficiency, but they are large in volume and occupy a large floor area, and their usage scenarios are restricted by the kitchen area. When the kitchen area is small, these two types of dishwashers cannot be used. The lid-lifting dishwasher, although small in space occupation and applicable to scenarios with a small kitchen area, usually has only one washing station, so its washing efficiency is lower than that of the other two types of dishwashers.

[0003] For the existing lid-lifting dishwashers, the height when the lid is lifted is higher than the height of the dishwasher in the working state. Therefore, when installing the dishwasher, a part of space needs to be reserved above the dishwasher to facilitate lifting the lid. For some usage scenarios with height restrictions, it is easy to be restricted when the lid of the lid-lifting dishwasher is lifted. There are also some multi-layer dishwashers in the prior art. The multi-layer washing stations are at different heights, and it is very laborious for the operator to carry in and out the dish basket, especially the dish basket at the upper washing station, from the dishwasher.

[0125] As Figure 1 and Figure 7 shown, in an alternative embodiment of the present utility model, the dishwasher body 1 has only one opening, the basket platform includes a first basket platform 51, the lifting mechanism includes a first lifting mechanism 31, and the control unit is electrically connected to the lifting mechanism; the basket sensor further includes:

[0126] A first inlet basket sensor 61, and the first inlet basket sensor 61 is provided on the first basket platform 51;

[0127] A first platform basket sensor 71, and the first platform basket sensor 71 is provided on the first lifting mechanism 31;

[0128] When starting the washing, when the first inlet basket sensor 61 and the first platform basket sensor 71 send a signal that the basket is not in place, the control unit controls the lifting platform 34 of the first lifting mechanism 31 to descend to the second position; when the first platform basket sensor 71 sends a signal that the basket is in place, the control unit controls the lifting platform 34 of the first lifting mechanism 31 to ascend to the first position;

[0129] When ending the washing, when the first inlet basket sensor 61 sends a signal that the basket is not in place and the first platform basket sensor 71 sends a signal that the basket is in place, the control unit controls the lifting platform 34 of the first lifting mechanism 31 to descend to the second position.

[0130] In this embodiment, in order to reduce the space occupied by the dishwasher, the dishwasher body 1 is configured to have a structure with only one opening. The first inlet basket sensor 61 is used to detect whether the dish basket 4 on the first basket platform 51 is in place, so as to prevent the lifting platform 34 from crushing the dish basket 4 on the basket platform 51 when it descends to the second position. The first platform basket sensor 71 is used to detect whether the dish basket 4 on the first lifting mechanism 31 is in place to confirm whether the operation of lowering the lifting platform 34 needs to be performed. The control unit controls the first lifting mechanism 31 to lift between the first position and the second position according to the signals of the first inlet basket sensor 61 and the first platform basket sensor 71, realizing the automatic lifting of the first lifting mechanism 31, facilitating the operator to load and unload the dish basket 4, further reducing the working intensity of the operator, helping to improve the cleaning efficiency, and at the same time being able to reduce the overall occupied area;

[0131] During specific operation: when starting the washing, when the first inlet basket sensor 61, the first platform basket sensor 71 and all the internal basket sensors 8 do not detect the dish basket 4, the control unit of the dishwasher body 1 controls the winding opening and closing mechanism 2 to open, realizing the full opening of the opening of the dishwasher body 1; at the same time, the control unit of the dishwasher body 1 controls the first lifting mechanism 31 to rise away from the first basket platform 51;

[0132] The operator places the dish basket 4 with tableware on the first basket platform 51 and pushes the dish basket 4 to the second washing position 122;

[0133] At this time, the internal basket sensor 8 at the second washing position 122 detects the dish basket 4, and the first inlet basket sensor 61 and the first platform basket sensor 71 do not detect the dish basket 4. The control unit of the dishwasher body 1 controls the first lifting mechanism 31 to descend to the surface of the first basket platform 51;

[0134] The operator places the dish basket 4 with tableware on the first lifting mechanism 31. The first platform basket sensor 71 detects the dish basket 4. The control unit of the dishwasher body 1 controls the first lifting mechanism 31 to rise to the first washing position 121. The operator pushes the dish basket 4 to the first washing position 121. At this time, the internal basket sensor 8 at the first washing position 121 detects the dish basket 4; if there are multiple first washing positions 121, the dish basket 4 is sent to all the first washing positions 121 in sequence through the above process. This process can be from top to bottom or from bottom to top, and no specific limitation is made here;

[0135] When all the internal bowl basket sensors 8 detect the dishwashing basket 4, the control unit of the dishwasher main body 1 controls the winding opening and closing mechanism 2 to close, achieving a complete closure of the opening of the dishwasher main body 1, and starting to spray and clean the tableware inside the dishwashing basket 4. After the spray cleaning is completed, this washing cycle ends. The control unit of the dishwasher main body 1 controls the winding opening and closing mechanism 2 to open, achieving a complete opening of the opening of the dishwasher main body 1, and performing the operation of taking out the dishwashing basket 4. The specific operation process of taking out the dishwashing basket 4 can be the reverse process of the above-mentioned operation process of feeding the dishwashing basket 4, which will not be elaborated here.

[0136] As Figure 8 and Figure 9 shown, in an alternative embodiment of the present invention, the first washing position 121 communicates with the second washing position 122; or, the second washing position 122 and the first washing position 121 are separated by a partition 17.

[0137] In this embodiment, when the first washing position 121 communicates with the second washing position 122, the structure of the dishwasher can be simplified; or, when the first washing position 121 and the second washing position 122 are separated by a partition 17, relatively independent cleaning of the first washing position 121 and the second washing position 122 can be achieved, avoiding the water droplets after upper-layer washing from falling onto the lower-layer dishwashing basket 4 and contaminating the tableware in the lower-layer dishwashing basket 4, which helps to ensure the cleaning effect;

[0138] In this embodiment, when the first washing position 121 and the second washing position 122 are separated by a partition 17, a liquid outlet pipe is provided inside each first washing position 121 to lead out the washing wastewater from the corresponding washing position, avoiding contamination of the washing position located in the lower layer.

[0139] As Figure 8 and Figure 9 shown, in an alternative embodiment of the present invention, the first washing position (121) is provided with a first spraying mechanism, and the second washing position 122 is provided with a second spraying mechanism. The spraying direction of the first spraying mechanism faces the first washing position 121, and the spraying direction of the second spraying mechanism faces the second washing position 122.

[0140] The first spraying mechanism is arranged at the top and / or bottom of the first washing position 121, and the second spraying mechanism is arranged at the top and / or bottom of the second washing position 122.

[0141] In this embodiment, by spraying and cleaning the dishwashing basket 4 in the first washing position 121 through the first spraying mechanism and spraying and cleaning the dishwashing basket 4 in the second washing position 122 through the second spraying mechanism, the spraying and cleaning effect of the tableware inside the dishwashing basket 4 can be ensured;

[0142] In this embodiment, the spraying mechanism of each washing position can be set according to actual needs. For example, for each washing position, a spraying mechanism can be set at the top of the washing position, or at the bottom, or both at the top and bottom according to actual needs. Or the spraying mechanism of some washing positions is set at the top, and the spraying mechanism of the remaining washing positions is set at the bottom;

[0143] In this embodiment, taking the dishwasher having two layers as an example, as Figure 8 shown, when the first washing position 121 and the second washing position 122 are communicated, the first spraying mechanism includes the first washing arm assembly 13, and the second spraying mechanism includes the second washing arm assembly 15. To improve the cleaning effect and simplify the equipment structure, a two-way washing arm assembly 14 can also be provided between the first washing position 121 and the second washing position 122. The two-way washing arm assembly 14 can spray simultaneously upward and downward; if there are multiple first washing positions 121, the two-way washing arm assembly 14 is provided between two adjacent first washing positions 121. At this time, the two-way washing arm assembly 14 not only serves as the first spraying mechanism to spray the first washing position 121, but also serves as the second spraying mechanism to spray the second washing position 122;

[0144] As Figure 9 shown, the first washing position 121 and the second washing position 122 are separated by a partition 17 to avoid the pollution of the lower washing position by the dripping liquid between the washing positions; the first spraying mechanism includes the third washing arm assembly 16. To improve the cleaning effect and efficiency, two third washing arm assemblies 16 are provided and are respectively located at the top and bottom of the first washing position 121; the second spraying mechanism includes the fourth washing arm assembly 18. To improve the cleaning effect and efficiency, two fourth washing arm assemblies 18 are provided and are respectively located at the top and bottom of the second washing position 122.

[0145] Those skilled in the art can understand that when the dishwasher has more than two layers, a partition 17 can be provided between each washing position to avoid the water droplets after washing in the upper layer from falling onto the lower layer and polluting the tableware in the lower dish basket 4.

[0146] Embodiment Two

[0147] The difference between Embodiment Two and Embodiment One lies in the different number of openings of the dishwasher body 1;

[0148] As Figure 10 and Figure 11 shown, in an optional embodiment of the present invention, the dishwasher body 1 has two openings, and the two openings are respectively used as the inlet side and the outlet side of the dishwasher body 1;

[0149] The lifting mechanism includes a second lifting mechanism 35 and a third lifting mechanism 36. The second lifting mechanism 35 is disposed on the inlet side of the dishwasher body 1, and the third lifting mechanism 36 is disposed on the outlet side of the dishwasher body 1;

[0157] When starting the washing, when the second inlet basket sensor 62 and the second platform basket sensor 72 send a signal indicating that the basket is not in place, the control unit controls the second lifting mechanism 35 to descend to the second position; when the third platform basket sensor 73 sends a signal indicating that the basket is not in place, the control unit controls the third lifting mechanism 36 to ascend to the first position;

[0158] When ending the washing, when the outlet basket sensor 63 sends a signal indicating that the basket is not in place and the third platform basket sensor 73 sends a signal indicating that the basket is in place, the control unit controls the third lifting mechanism 36 to descend to the second position.

[0159] In this embodiment, at the start of washing, the second inlet basket sensor 62 is used to detect whether the dish basket 4 on the second basket platform 52 is in place, so as to prevent the lifting platform 34 of the second lifting mechanism 35 from crushing the dish basket 4 on the second basket platform 52. The second platform basket sensor 72 is used to detect whether the dish basket 4 on the second lifting mechanism 35 is in place to confirm whether the second lifting mechanism 35 needs to be lowered. The control unit controls the lifting platform 34 of the second lifting mechanism 35 to lift between the first position and the second position according to the signals of the second inlet basket sensor 62 and the second platform basket sensor 72, realizing the automatic lifting of the second lifting mechanism 35, facilitating the operation of the operator on the inlet side to send in the dish basket 4, and helping to improve the cleaning efficiency. Moreover, the third platform basket sensor 73 is used to detect whether the dish basket on the third lifting mechanism 36 is in place, and when it is not in place, the lifting platform 34 of the third lifting mechanism 36 is lifted to the first position, so that the third lifting mechanism 36 can wait in advance at the outlet of the first washing position 121, so that the dish basket 4 can be promptly moved out onto the third lifting mechanism 36 after washing, improving the washing efficiency.

[0160] The outlet basket sensor 63 is used to detect whether the dish basket 4 on the third basket platform 53 is in place to prevent crushing the dish basket 4 on the third basket platform 53. The third platform basket sensor 73 is used to detect whether the dish basket 4 on the third lifting mechanism 36 is in place to confirm whether the dish basket 4 has reached the third lifting mechanism and is waiting for transportation. The control unit controls the third lifting mechanism 36 to lift between the first position and the second position according to the signals of the outlet basket sensor 63 and the third platform basket sensor 73, realizing the automatic lifting of the third lifting mechanism 36, facilitating the operation of the operator on the outlet side to take out the dish basket 4, and helping to improve the cleaning efficiency.

[0161] During specific operation:
