Description

Technical Field

[0001] The present invention relates to the field of dishwashing equipment, in particular to a dishwasher. Background Art

[0002] After running the dishwasher many times, the machine itself will inevitably be contaminated to varying degrees, especially its filter system. The filter system is generally composed of one or more filters. During the washing process of the dishwasher, the filter system continuously filters the washing water mixed with physical residues to make the circulating washing water relatively clean. After running many times, the residues are easy to clog the mesh of the filter system, which will not only affect the efficiency of the water circulation during the washing process, but also easily breed bacteria if the residues are not discharged in time from the filter system. Most of the existing filter systems of dishwasher products do not have a self-cleaning function, and users need to disassemble the filter system for manual cleaning.

[0003] At present, some dishwashers are equipped with self-cleaning filtering devices. However, the self-cleaning filtering devices set cleaning particles in a cavity between the coarse filter and the fine filter of the dishwasher. The cleaning particles collide and rub against the coarse filter and the fine filter with the water flow to achieve automatic cleaning of the coarse filter and the fine filter.

[0004] However, the above dishwasher is limited by the water return speed and the friction resistance of its own structure during rotation, and cannot achieve a good self-cleaning effect, and cannot effectively clean the flat filter, filter base, etc. Summary of the invention

[0005] The main purpose of the present invention is to provide a dishwasher to solve the problem that the dishwasher in the prior art cannot effectively clean its filter system.

[0007] Furthermore, the rotating part is an impeller.

[0008] Furthermore, the dishwasher also includes: a first magnetic suspension component, which is arranged on the rotating part; a second magnetic suspension component, which is arranged on the water cup assembly, the second magnetic suspension component is adapted to the first magnetic suspension component, and after the second magnetic suspension component is powered on, the second magnetic suspension component makes the first magnetic suspension component and the rotating part suspended in the accommodating cavity and rotatably arranged; after the second magnetic suspension component is powered off, the second magnetic suspension component adsorbs the first magnetic suspension component on the water cup assembly.

[0009] Furthermore, the first magnetic suspension component and the second magnetic suspension component are arranged opposite to each other along a first preset direction, and a rotation center line of the rotating part extends along the first preset direction.

[0010] Furthermore, the second magnetic suspension component is arranged at the bottom of the water cup assembly and is located outside the water cup assembly.

[0011] Furthermore, the rotation centerline of the rotating part extends in the vertical direction, the rotating part has a first end and a second end arranged opposite to each other in the vertical direction, the first end is located below the second end, and the first magnetic suspension component is arranged at the first end of the rotating part.

[0012] Furthermore, the first magnetic suspension component is a permanent magnet.

[0013] Furthermore, the second magnetic suspension component is an electromagnet.

[0014] Furthermore, the filtering system includes: a base connected to the shell; a filter connected to the base; and a filter screen arranged around the outer side of the filter.

In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0029] The present invention provides a dishwasher, please refer to Figures 1 to 6 , including: a shell 10, the shell 10 has an inner cavity 11, the inner cavity 11 includes a dishwashing cavity 111 and a groove 112 located below the dishwashing cavity 111; a filtering system 20, arranged in the groove 112; a water cup assembly 30, the water cup assembly 30 is arranged at the bottom of the inner cavity 11, and the accommodating cavity 31 of the water cup assembly 30 is connected to the groove 112; a rotating part 40, arranged in the accommodating cavity 31 and located below the filtering system 20, and the rotating part 40 is rotatably arranged in the accommodating cavity 31.

[0030] The dishwasher of the present invention includes a housing 10, a filter system 20, a water cup assembly 30 and a rotating part 40. The filter system 20 is arranged in the housing 10, the water cup assembly 30 is arranged below the filter system 20, and the rotating part 40 is arranged in the accommodating cavity 31 of the water cup assembly 30; the rotating part 40 is rotatably arranged in the accommodating cavity 31, so that the rotating part 40 drives the water in the water cup assembly to move, thereby realizing the cleaning of the filter system, thereby solving the problem that the dishwasher cannot effectively clean its filter system.

[0031] In this embodiment, the rotating part 40 is an impeller. In a specific implementation, the impeller includes a rotating shaft and a plurality of blades, the plurality of blades are evenly distributed around the circumference of the rotating shaft, and the first magnetic suspension component 50 is fixedly connected to the rotating shaft.

[0032] Preferably, the rotating shaft is a hollow shaft, and such a configuration facilitates the suspension of the impeller.

[0033] In this embodiment, the dishwasher further comprises: a first magnetic suspension component 50, which is arranged on the rotating part 40; a second magnetic suspension component 60, which is arranged on the water cup assembly 30, and the second magnetic suspension component 60 is adapted to the first magnetic suspension component 50. After the second magnetic suspension component 60 is powered on, the second magnetic suspension component 60 makes the first magnetic suspension component 50 and the rotating part 40 suspended in the accommodating chamber 31 and rotatably arranged; after the second magnetic suspension component 60 is powered off, the second magnetic suspension component 60 adsorbs the first magnetic suspension component 50 on the water cup assembly 30. Such a setting not only provides driving force for the rotating part 40, but also ensures the sealing of the drive, avoiding leakage problems caused by pure mechanical transmission (such as a transmission mode in which the driving device drives the rotating shaft to rotate, and the rotating shaft drives the rotating part to rotate).

[0034] Specifically, the second magnetic suspension component 60 can generate an alternating magnetic field to drive the first magnetic suspension component 50 and the rotating part 40 to be suspended in the accommodating cavity 31 and rotatably arranged.

[0035] In this embodiment, the first magnetic suspension component 50 and the second magnetic suspension component 60 are disposed opposite to each other along a first preset direction, and the rotation center line of the rotating part 40 extends along the first preset direction.

[0036] Preferably, the second magnetic suspension component 60 is disposed at the bottom of the water cup assembly 30 and is located outside the water cup assembly 30 .

[0037] Preferably, the rotation centerline of the rotating part 40 extends in the vertical direction, the rotating part 40 has a first end and a second end arranged opposite to each other in the vertical direction, the first end is located below the second end, and the first magnetic suspension component 50 is arranged at the first end of the rotating part 40. Such an arrangement has better disturbance to the water flow in the water cup assembly.

[0038] In this embodiment, the first magnetic suspension component 50 is a permanent magnet.

[0039] In this embodiment, the second magnetic suspension component 60 is an electromagnet or a structural component that can generate an alternating magnetic field.

[0040] In this embodiment, the filter system 20 includes: a base 21 connected to the housing 10; a filter 22 connected to the base 21; and a filter screen 23 disposed around the outer side of the filter 22. The filter screen 23 is a flat filter screen.

[0041] Preferably, the filter 22 is a microfilter, which has a better filtering effect.

[0042] In this embodiment, the dishwasher further includes a spray arm 70 , which is disposed in the dishwashing cavity 111 to rinse the kitchen utensils in the dishwashing cavity 111 .

[0043] In this embodiment, the dishwasher further includes a door body, which is disposed on the housing 10 and is rotatably disposed relative to the housing 10 to achieve opening and closing of the housing 10 .

[0044] The dishwasher of the present application solves the following technical problems: realizing automatic cleaning of the filter system of the dishwasher; and solving the sealing problem of the impeller drive.

[0045] The beneficial effects of the dishwasher of the present application are: improving the user experience and solving the problem of automatic cleaning of the filtration system.

[0046] The inventive point of the dishwasher of the present application is that the rotation of the impeller is realized by the first magnetic suspension component 50 and the second magnetic suspension component 60 to perform self-cleaning of the filter system of the dishwasher.

[0047] After the dishwasher has been used for many times, the inner cavity and filter system of the dishwasher will be scaled and contaminated, so the machine needs to be cleaned. Currently, the self-cleaning function of many dishwashers on the market only has a simple flushing process for the inner cavity of the dishwasher, but it cannot clean the pollutants and residues in the mesh of the filter system very well, and the user still needs to perform a secondary cleaning, otherwise it is easy to cause secondary contamination of the tableware. Among them, there are many meshes in the filter system, which are very easy to be blocked and retain residues, and need to be cleaned after multiple uses. The specific implementation methods of this application are:

[0048] When the dishwasher is not in operation, the first magnetic suspension component 50 and the second magnetic suspension component 60 , as common magnetic components, can attract each other, so that the first magnetic suspension component 50 is fixedly attracted to the water cup assembly.

[0049] After the self-cleaning function is turned on, the water volume in the dishwasher must at least cover the height of the flat filter; when the dishwasher is powered on, the second magnetic suspension component 60 is powered on to generate a magnetic field, thereby causing the first magnetic suspension component 50 and the rotating part 40 to suspend at a certain height in the water cup assembly (that is, the rotating part 40 and the first magnetic suspension component 50 are not in contact with other components). Figure 2 As shown, an alternating magnetic field is generated in the second magnetic suspension component 60, which can be used as a driving device to rotate the rotating part 40 and the first magnetic suspension component 50. The rotation of the rotating part 40 drives the water in the water cup assembly to move and clean the filter system.

[0050] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0051] The dishwasher of the present invention includes a housing 10, a filter system 20, a water cup assembly 30 and a rotating part 40. The filter system 20 is arranged in the housing 10, the water cup assembly 30 is arranged below the filter system 20, and the rotating part 40 is arranged in the accommodating cavity 31 of the water cup assembly 30; the rotating part 40 is rotatably arranged in the accommodating cavity 31, so that the rotating part 40 drives the water in the water cup assembly to move, thereby realizing the cleaning of the filter system, thereby solving the problem that the dishwasher cannot effectively clean its filter system.
