The dishwasher of this scheme takes out the cleaned dishes when the cover 2 is opened after washing the dishes. Since the washing mechanism is located on the cover 2, the washing mechanism is taken out together when the cover 2 is opened, so that only the cleaned dishes or fruits and vegetables remain in the cavity 1. After taking out the objects to be cleaned, there is no object in the cleaning space of the cavity 1, and the user can easily wipe and clean the cavity 1. Compared with the prior art, the cleaning dead corners are basically eliminated, and it is easier to remove the material basis for the breeding of bacteria, so it is not easy to produce odor. And because it is convenient for users to do daily maintenance, it also greatly increases the service life of the dishwasher.

[0132] There is no specific limitation on the structure of the washing mechanism. In this embodiment, Figure 2 , Figure 4 As shown, the washing mechanism includes: a washing arm 41, one end of which is arranged under the cover body 2, and the other end extends toward the cavity 1, including an output hole 42 arranged on the washing arm 41; a washing tank 44, which is arranged on the cover body 2 and is used to hold liquid and / or solid cleaning agents, and the washing tank 44 is connected to the output hole 42 through a supply channel 43. The washing arm 41 is used to spray detergent into the cleaning space, and the detergent is sprayed into the cleaning space through the output hole 42. After the object to be cleaned is placed in the cleaning space, the cleaning agent is first sprayed on the object to be cleaned, so that the cleaning agent is fully reflected on the surface of the object to be cleaned, and then water is injected into the cavity 1 for cleaning. As an alternative embodiment, the washing arm 41 has a. As another alternative embodiment, such as Figure 4 , Figure 5 As shown, there are four wash arms 41 .

[0133] There is no specific limitation on the distribution of the washing arms 41. In this embodiment, Figure 5 , Figure 7 As shown, the washing arms 41 are evenly distributed around the circumference.

[0134] There is no specific limitation on the structure of the supply channel 43. In this embodiment, Figure 3 , Fig. 9 As shown, the supply channel 43 is arranged in the washing arm 41.

The second motor 51 is located in the installation chamber 46 and is closed by the sealing cover 461, so that the working environment of the second motor 51 is isolated from the external environment of the washing arm 41. This prevents the washing arm 41 from working in the liquid and affecting the working of the second motor 51.

[0141] There is no specific limitation on the structure of the washing arm 41. In this embodiment, Figure 8 , Fig. 9 As shown, the washing arm 41 at least includes: a low water level detection point 47 and a high water level detection point 48 distributed along the length direction of the washing arm 41. The high water level detection point 48 and the low water level detection point 47 can detect the amount of water to remind the user to add water. It can also play a protective role when the user removes the cover body 2. If the washing mechanism is still in the working state when the cover body 2 is removed, the high water level detection point 48 and the low water level detection point 47 will be separated from the liquid surface in turn, and the system will automatically stop working when the low water level is detected during operation. It provides a judgment basis for the safety system and provides protection for the safety of the user.

[0142] There is no specific limitation on the structure of the washing mechanism. In this embodiment, the washing mechanism further includes: a heating module 7, which is located on the washing arm 41 and is arranged away from the cover body 2. The heating module 7 is arranged away from the cover body 2 to ensure that the heating module 7 is in contact with the cleaning liquid. In different cleaning modes, the cleaning liquid can be heated to meet different cleaning temperature requirements. The diversity of the washing modes of the dishwasher is improved to achieve scientific cleaning. As an alternative embodiment, the heating module 7 is arranged on the first blade 31 and / or the second blade 35.

[0143] There is no specific limitation on the connection structure between the washing mechanism and the cover 2. In this embodiment, Figure 2 , Figure 3As shown, the washing mechanism further includes: a bracket 4, which is detachably arranged on the side of the cover 2 facing the cavity 1, and there is a space for installing electronic components between the bracket 4 and the cover 2; a control panel 21, which is arranged on the surface of the cover 2 away from the cavity 1, and the control panel 21 is electrically connected to the electronic components. The bracket 4 connects the washing mechanism and the cover 2 together, and provides an installation space for components such as circuits that control the operation of the washing mechanism. As an alternative embodiment, the cover 2 and the bracket 4 are integrally formed.

[0144] There is no specific limitation on the location of the washing tank 44. Figure 2 As shown, the washing tank 44 is arranged on the bracket 4, and the opening of the washing tank 44 is arranged toward the cover body 2. The washing tank 44 is used to contain solid or liquid cleaning agents. The cleaning agents in the washing tank 44 can be replenished or replaced by opening the cover body 2. As an alternative embodiment, when the cover body 2 and the bracket 4 are integrally formed, an opening for taking out and placing the washing tank 44 is provided on the bracket 4 corresponding to the washing tank 44. As an alternative embodiment, Fig.11 As shown, a placement cover 23 is provided on the cover body 2 at a position corresponding to the washing tank 44 , and detergent is added into the washing tank 44 by opening the placement cover 23 .

[0145] There is no specific limitation on the structure of the bracket 4. In this embodiment, Figure 2 , Figure 4 , Figure 5 As shown, the bracket 4 includes: a support portion 45, which is protruding from the bracket 4 and supported at the open end of the cavity 1. The bracket 4 is supported on the opening of the cavity 1 by the support portion 45, and the washing arm 41 located below the bracket 4 extends into the cavity 1. On the one hand, the bracket 4 indirectly closes the opening of the cavity 1, and on the other hand, the bracket 4 makes it easier to lift the cover 2 and the washing mechanism out of the cavity 1, which is convenient for users to operate.

[0146] There is no specific limitation on the structure of the washing mechanism. In this embodiment, Figure 5 , Figure 6 As shown, the washing mechanism also includes a stirring assembly 3, which includes: a first blade 31, one end of which is movably connected to the side of the cover body 2 facing the cavity 1, and the other end extends to the cavity 1. The cover body 2 is provided with a first motor 22, and the first blade 31 is controlled by the first motor 22 to rotate relative to the cover body 2. The first blade 31 is arranged around the washing space, and during the washing operation, it revolves relative to the washing object. Agitation of the washing liquid in a relatively large range is achieved. As an alternative embodiment, Figure 7 As shown, the washing mechanism is not provided with an agitating assembly 3 .

[0147] There is no specific limitation on the shape of the first blade 31. In this embodiment, Figure 3 , Figure 6As shown, the first blade 31 is tilted. When the first blade 31 is tilted, the area for pushing the cleaning liquid is increased, and it is easier to drive the entire cleaning liquid to flow.

[0148] There is no specific limitation on the number of the first blades 31. Figure 4 , Figure 6 As shown, there are multiple first blades 31, and the first blades 31 are arranged near the inner wall of the cavity 1, and the multiple first blades 31 are arranged around the cleaning object. When the first blades 31 arranged near the inner wall of the cavity 1 rotate around the cleaning space under the control of the first motor 22, more liquid is surrounded between the first blades 31, thereby increasing the influence range of the first blades 31 when rotating and improving the efficiency of stirring the water flow.

[0149] There is no specific limitation on the distribution of the first blades 31. In this embodiment, Figure 4 , Figure 5 As shown, a plurality of first blades 31 form a group, and the first blades 31 in each group have the same spacing and the same inclination angle. The entire stirring assembly 3 has a plurality of groups of first blades 31, and there is a clearance gap between each group of first blades 31. When the stirring assembly 3 is used in conjunction with the washing arm 41, the washing arm 41 is arranged just opposite the clearance gap at the initial position of washing, and at this time, the first blades 31 can reduce the obstruction of the detergent spray.

[0150] There is no specific limitation on the manner in which the washing arm 41 is exactly opposite to the clearance gap. Figure 2 , Fig.11 As shown, an iron sheet 36 is arranged on the back side of the first blade 31, that is, on the rib 34 of the base plate 32. An electromagnet 37 is arranged on the bracket 4 at the position of the iron sheet 36, and a DC adapter 38 for controlling the electromagnet 37 is also arranged on the bracket 4. When the iron sheet 36 is adsorbed on the electromagnet 37 accordingly, the washing arm 41 is just located within the range of the clearance. When the whole machine is stopped, the stirring assembly 3 can rotate freely relative to the motor 22 to protect the motor. When it is necessary to spray detergent, the controller provides a signal to control the electromagnet 37 to generate magnetic force, thereby adsorbing the iron sheet, so that the position of the stirring assembly 3 is corrected, so that the washing arm 41 is just located within the range of the clearance. When the dishwasher enters other programs that require the stirring assembly 3 to rotate, the electromagnet 37 is powered off, and the stirring assembly 3 is controlled by the motor 22 again.

[0151] There is no specific limitation on the structure of the stirring assembly 3. In this embodiment, Figure 5 , Figure 6As shown, the stirring assembly 3 also includes: a second blade 35, which is located on the side of the cover body 2 facing the cavity 1 and protrudes, and the two ends of the second blade 35 in the length direction extend in a direction parallel to the cover body 2. The second blade 35 is arranged parallel to the cover body 2. After the tableware or fruits and vegetables are washed, the second blade 35 continues to rotate, driving the air flow in the cavity 1 to accelerate the air drying of the tableware, fruits and vegetables. The second blade 35 provides downward power for the water. If there is no slope and it is connected, it provides a vertical downward water flow similar to a straight cylinder. In this embodiment, the blades of the second blade 35 have an inclined angle, guiding the water flow to flow to the outside away from the rotation center, and the middle part corresponding to the rotation center is disconnected and does not provide power, so that the water flow can go down from the outer circle, pass through the bottom and go up from the middle, forming a longitudinal water flow circulation in the water depth direction, preventing water flow turbulence and splashing. As an alternative embodiment, the second blade 35 is replaced by an air outlet, and the air outlet outputs hot air into the cleaning space.

[0152] There is no specific limitation on the structure of the stirring assembly 3. In this embodiment, Figure 6 As shown, the stirring assembly 3 further includes: a base plate 32, which is rotatably connected to the cover body 2, and a first blade 31 and a second blade 35 are arranged on a side of the base plate 32 facing the cavity 1. The base plate 32 is controlled by the first motor 22 to rotate, thereby driving the first blade 31 and the second blade 35 to rotate, thereby achieving the function of stirring the cleaning liquid or disturbing the airflow to form wind.

[0153] The first blade 31 is similar to the structure of a centrifugal wind wheel. When rotating, it pushes the water flow to gather in the middle, and then cooperates with the second blade 35 to form a circulating water flow. There is no specific limitation on the inclination angle of the first blade 31 and the second blade 35. In this embodiment, the inclination angle of the first blade 31 is [30°, 60°], and the inclination angle of the second blade 35 is [10°, 30°]. Within the above angle range, the water flow circulation formed by the cooperation of the two can minimize the occurrence of splashing while ensuring the cleaning efficiency. As an alternative embodiment, the first blade 31 and the second blade 35 are not inclined, which can also meet the cleaning requirements.

[0154] There is no specific limitation on the structure of the bracket 4. In this embodiment, the bracket has a plurality of cavities with openings toward the cover 2. Most of the cavities are used to install components such as controllers, circuits, and display components. Figure 3 , Fig.11As shown, the bracket 4 has a cross-shaped cavity, the first purpose of which is to separate the electrical components from the water in the dishwasher, the second purpose is to isolate the cavities from each other, to separate the strong current from the weak current, and the third purpose is to further increase the structural strength of the bracket. In order to meet safety requirements, the cover 2 is usually not opened. At the same time, the motor is isolated from other cavities for strong current, the motherboard controller is arranged in one of the cavities with strong and weak current, and the display component is arranged in other cavities. The above two cavities are sealed to prevent users from electric shock or water from entering. The washing tank 44 is a separate cavity, and the user can put detergent by opening the delivery cover 23, and other things can be placed in other idle cavity areas, such as DC adapters. There is no specific restriction on the specific number of cavities, and those skilled in the art will divide it according to actual functional requirements.

[0155] There is no specific limitation on the structure of the dishwasher. In this embodiment, Figure 2 , Figure 3 As shown, it also includes: a protective cover 8, which is detachably arranged on the cover body 2, surrounds the washing mechanism, and has a plurality of through holes distributed on the protective cover 8. The protective cover 8 prevents the user from touching the washing mechanism, providing a guarantee for the user's safe use. The through holes on the protective cover 8 facilitate the passage of cleaning liquid and airflow, reducing the impact on the washing work.

[0156] There is no specific limitation on the structure of the protective cover 8. In this embodiment, Figure 2 , Figure 3 As shown, the protective cover 8 is at least a two-layer mesh cover structure, and the washing mechanism is arranged between the two layers of the mesh cover structure to prevent the tableware from directly contacting the washing mechanism and causing collision.

[0157] There is no specific limitation on the connection method between the protective cover 8 and the cover body 2 or the bracket 4. In this embodiment, Figure 2 , Figure 3 As shown, a connection portion 81 is protruded from the protective cover 8, and a matching portion 49 adapted to the connection portion 81 is provided below the cover body 2. The protective cover 8 is detachably provided on the cover body 2, which is convenient for cleaning, repair and replacement of the protective cover 8. At the same time, after the protective cover 8 is removed, the stirring assembly 3 and the washing arm 41 are exposed, which is convenient for users to clean and repair. As an alternative embodiment, the protective cover 8 is hung on the cover body 2 or the bracket 4 by a hook. As another alternative embodiment, the protective cover 8 is fastened to the cover body 2 or the bracket 4 by bolts.

[0158] There is no specific limitation on the structure of the dishwasher for holding tableware or fruits and vegetables. Figure 2 , Figure 3 As shown, it also includes: a basket 6, which is arranged in the cavity 1 and is used to place the washing objects. The basket 6 forms a limit for tableware, fruits and vegetables to prevent the tableware from colliding with the washing mechanism.

[0159] There is no specific limitation on the structure of the basket 6. In this embodiment, Figure 2 , Figure 3 As shown, the basket 6 includes: a pulley, which is arranged below the basket 6 to support the basket 6 on the bottom surface inside the cavity 1. When the cleaning agent is not used, the basket 6 can be placed outside the equipment to form a temporary dish rack. The pulley facilitates the movement of the temporary dish rack.

[0160] There is no specific limitation on the structure of the cavity 1. In this embodiment, Figure 1 , Figure 2 , Figure 3 As shown, the cavity 1 includes: a water injection hole 11 and a drainage hole 12. The water injection hole 11 is arranged near the top of the cavity 1, and the drainage hole 12 is arranged near the drainage hole 12. The water injection hole 11 can be connected to a water pipe to realize the automatic water inlet function of the dishwasher under the drive of a water pump.
