[0024] refer to Figure 1-3 This embodiment provides a dishwasher, which includes a base 1 and a cover 7 arranged on the base 1. The cover 7 and the base 1 are arranged to form a second accommodating cavity (not shown in the figure), and the second accommodating cavity is used to hold dishes to be washed.

[0025] In this embodiment, a back plate 8 is provided on the base 1, and the cover body 7 is slidably connected to the back plate 8 via a slide rail, so that the dishwasher can be opened and closed by lifting the cover body 7 upward and sliding it downward.

[0026] In this embodiment, the base 1 is provided with first panels 11 that are relatively arranged, and a second panel 12 that is arranged between the two first panels 11, wherein a first mounting plate 21 is provided on one end of one of the first panels 11 close to the second panel 12, and the first mounting plate 21 is connected to the first panel 11 through second mounting plates 22 that are arranged on both sides of the first mounting plate 21, and the first mounting plate 21, the second mounting plate 22 and the first panel 11 are arranged to form a third accommodating cavity 26, and a fourth accommodating cavity 35 is provided on the side of the third accommodating cavity 26 away from the second panel 22, and the fourth accommodating cavity 35 is surrounded by two relatively arranged third mounting plates 31 and a fourth mounting plate 32 connected to the two third mounting plates 31. The third accommodating chamber 26 is used to place the electronic control components of the dishwasher. The electronic control components are fixed on the first mounting plate 21 for easy installation. The fourth accommodating chamber 35 is used to place a bucket for containing cleaning liquid for washing dishes, so that it can be used without an external water source and is suitable for various occasions. Moreover, the third accommodating chamber 26 and the fourth accommodating chamber 35 are separated, which effectively prevents the liquid in the bucket from affecting the components in the third accommodating chamber 26, thereby ensuring safe use.

[0027] The first mounting plate 21 is provided with a plurality of fixing holes 23 for fixing electronic control components, which facilitates the installation and fixing of the components. The lower portion of the second mounting plate 22 is provided with a first through hole 24, and the first mounting plate 21 close to the second panel 12 is provided with a second through hole 25. The above arrangement effectively ensures the ventilation and heat dissipation of the electronic control components, and can also reduce the overall weight of the dishwasher.

[0028] The third mounting plate 31 or the fourth mounting plate 32 is provided with a third strip-shaped through hole 33, and the upper portion of the third mounting plate 31 is provided with a fourth through hole (not shown in the figure). The arrangement of the third through hole 33 reduces the weight of the dishwasher, and the staggered arrangement of the fourth through hole and the second through hole 25 effectively prevents the cleaning liquid in the bucket from splashing onto the electronic control components during the process of moving the dishwasher or placing the bucket.

[0029] In addition, a fifth mounting plate 34 is provided on the upper portion of the third mounting plate 31 , and the fifth mounting plate 34 is connected to the two third mounting plates 31 , thereby forming a complete closed space together with the door on the base 1 .

[0030] The dishwasher in this embodiment also includes a first water tank 41 arranged on the base 1, and a second water tank 42 arranged in the first water tank 41, the second water tank 42 includes a first outer shell 421, the first outer shell 421 is surrounded by a first accommodating cavity (not shown in the figure) for accommodating liquid, the first outer shell 421 is made of heat-conducting material, and the second water tank 421 is provided with a heating element (not shown in the figure). When in use, it is only necessary to heat the water in the second water tank 42. Through the heat conduction effect of the first outer shell 421, the water temperature in the first water tank 41 will also reach a corresponding temperature (which may be the same as or different from the water temperature in the second water tank 42). There is no need to separately set a heating element in the first water tank 41, and the second water tank 42 is arranged in the first water tank 41, which also improves the overall space utilization and makes the overall volume of the dishwasher smaller.

[0031] In this embodiment, the water temperature in the second water tank 42 is controlled between 90 and 95 degrees, and the temperature in the first water tank 41 is controlled between 40 and 60 degrees. The water temperature in the first water tank 41 does not need to be too high, nor does it need to be precisely controlled.

[0032] In this embodiment, it also includes a first water spray component (not shown in the figure) connected to the first water tank 41, and a second water spray component (not shown in the figure) connected to the second water tank 42. The first water spray component is used to wash dishes, and the second water spray component is used to rinse the washed dishes. Therefore, the first water spray component is connected to the first water tank 41, and the second water spray component is connected to the second water tank 42.

[0033] In this embodiment, the second water spray component and the first water spray component are arranged in the second accommodating chamber, and the first water tank 41 is connected to the second accommodating chamber. The water used to rinse the dishes will flow into the first water tank 41 through the liquid route designed in the second accommodating chamber, so that the cleaning liquid can be effectively recycled and water can be saved. When there is no external water source, the cleaning liquid in the bucket can be used for a long time.

[0034] In this embodiment, the first water tank 41 is provided with a first detection component (not shown in the figure) for detecting the liquid level height or liquid volume in the first water tank 41. The first detection component is electrically connected to the water pump. The water pump is started only after the liquid level or water volume in the first water tank 41 reaches a preset height or volume, so as to prevent the water pump from running in the absence of water.

[0035] The second water tank 42 is provided with a second detection element (not shown in the figure) for detecting the temperature of the liquid in the second water tank 42. The second detection element is electrically connected to the water pump and the heating element. When the temperature in the second water tank 42 reaches the requirement, the water pump starts to operate. When the temperature in the second water tank 42 reaches the set maximum temperature, the heating element stops heating, thereby ensuring that the water temperature in the second water tank 42 is stable and will not overheat.

[0036] In this embodiment, the first detection member may be a float, which changes with the height of the liquid level, thereby detecting the height of the liquid level in the first water tank 41. In addition, the dishwasher also includes a first solenoid valve (not shown in the figure) provided between the first water tank 41 and the water pump, and a second solenoid valve (not shown in the figure) provided between the second water tank 42 and the water pump. Through the setting of the first solenoid valve and the second solenoid valve, the water pump can be controlled to extract water from the first water tank 41 or the second water tank 42, so that only one water pump is required to pump water from two different water tanks.

[0037] In this embodiment, a drain plate 6 is provided above the first water tank 41, and an overflow hole is provided in the first water tank 41. The setting of the drain plate 6 can effectively prevent solid impurities on the dishes from entering the first water tank 41, which facilitates cleaning. After the water used to clean the dishes enters the first water tank 41, the oil will float above the liquid in the first water tank 41 because the density of the oil is less than that of water. When the liquid level in the first water tank 41 reaches the height of the overflow hole, the oil will first flow out through the overflow hole, thereby ensuring the recycling of the cleaning liquid and the cleanliness of the liquid in the first water tank 41.

[0038] The dishwasher described in this embodiment, after being powered on, the water pump first fills water from a water bucket or an external water source into the second water tank 42 and heats it. By detecting the water level in the first water tank 41, if the water level in the first water tank 41 is lower than a preset height, water is pumped from the second water tank 42 by the water pump, and water is sprayed into the second accommodating chamber by the first water spraying member or the second water spraying member. The water in the second accommodating chamber flows into the first water tank 41 through a set line. When the liquid level in the first water tank 41 reaches the set height, pumping water is stopped. When in use, the user first opens the cover 7, puts the dishes to be washed into the second accommodating chamber, pumps water from the first water tank 41 by the water pump, sprays water by the first water spraying member, and rinses the dishes. After the rinsing is completed, the water in the second water tank 42 is sprayed out by the second water spraying member to rinse the dishes again.

[0039] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
