Description

Technical Field

[0001] The present invention relates to the technical field of kitchen appliances, and particularly to a water cup structure of a dishwasher, a dishwasher and an operation method thereof. Background Art

[0002] With the development and progress of society, people's pursuit of a higher quality of life often promotes the development of some industries and the progress of technology. As an item that people often come into contact with in their daily lives, dishwashers have an increasingly greater impact on people's lives. As a kitchen appliance, dishwashers eliminate the trouble of users washing dishes and have been favored by more and more families in recent years.

[0003] During the washing process of a dishwasher, the filtration system filters food residues to prevent the food residues from causing secondary pollution to tableware through the water flow system. In particular, fine food particles will be blocked in the water cup by the micro-filtration net system. When the drainage system works, most of the particles are discharged out of the cavity with the drainage system. However, a small part of the food particles still adhere to the micro-filtration net system and cannot be drained away, resulting in the user having to regularly disassemble and wash the micro-filtration net system. If not washed in time, the food residues adhering to the micro-filtration net system are likely to deteriorate and rot, thereby generating odors and breeding bacteria, posing a risk of secondary pollution to the tableware and causing great discomfort to the user.

[0050] The following embodiments illustrate the present invention, but the present invention is not limited by these embodiments. Modifications to the specific embodiments of the present invention or equivalent replacements of some technical features, without departing from the spirit of the present invention, shall fall within the scope of the technical solutions claimed in the present invention.

[0051] Please refer to Figures 1-6 , the present invention provides a water cup structure for a dishwasher, which includes a water cup body 11, a filtering component 12, a flushing component 14, and an ultrasonic module 13. The water cup body 11 is installed on the chassis 2 of the washing inner cavity of the dishwasher. An upwardly opening water filtering cavity 10 is formed on the water cup body 11. The filtering component 12 is installed in the water filtering cavity 10 for filtering dirt. The flushing component 14 has its water inlet end and water outlet end both communicating with the water filtering cavity 10. The water in the water filtering cavity 10 flows into the flushing component 14 after passing through the filtering component 12, and the water outlet end of the flushing component 14 is arranged to face the filtering component 12. The ultrasonic module 13 is installed on the water cup body 11 and communicates with the water filtering cavity 10 for providing micro-nano bubbles to the water filtering cavity 10.

[0052] Since micro-nano bubbles generally burst in about 1 s, therefore, in the water cup assembly provided by the present invention, by arranging the ultrasonic module 13 on one side of the water filtering cavity 10 on the water cup body 11, the micro-nano bubbles generated by the ultrasonic module 13 can quickly enter the water filtering cavity 10 and act on the dirt (including oil stains and food residues) on the filtering component 12. Utilizing the energy released when the micro-nano bubbles burst, emulsify and decompose the dirt attached to the filtering component, and then use the flushing component 14 to spray water towards the filtering component 12, thereby flushing away the dirt on the filtering component 12, and thus realizing self-cleaning of the filtering component 12 of the dishwasher, with a good cleaning effect.

[0053] Optionally, an installation cavity communicating with the water filtering cavity 10 is formed on the side wall of the water filtering cavity 10, and the ultrasonic module 13 is arranged in the installation cavity. In this way, it is beneficial to install the ultrasonic module 13, making the ultrasonic module 13 located on the side wall of the water filtering cavity 10, and the micro-nano bubbles generated by the ultrasonic module 13 can quickly enter the water filtering cavity 10. At the same time, arranging the ultrasonic module 13 on the side wall of the water filtering cavity 10 will not affect the installation of the filtering component 12 in the water filtering cavity 10.

[0054] Optionally, the flushing assembly 14 includes a water-passing valve body 141, a water distribution valve plate 145, and a flushing component. The water-passing valve body 141 is installed on the water cup body 11. An inlet, a water cup flushing outlet 144, and a tableware flushing outlet are formed on the water-passing valve body 141. The tableware flushing outlet is communicated with the spray arm assembly of the dishwasher. The water distribution valve plate 145 is installed on the water-passing valve body 141. The water distribution valve plate 145 can open one of the water cup flushing outlet 144 and the tableware flushing outlet, so that one of the water cup flushing outlet 144 and the tableware flushing outlet is communicated with the inlet. The flushing component is installed on the periphery of the filtering assembly 12 and is communicated with the water cup flushing outlet 144. When it is necessary to execute the cleaning program for the filtering assembly 12, the water distribution valve plate 145 opens the water cup flushing outlet 144, so that the water cup flushing outlet 144 is communicated with the inlet. The water in the dishwasher can flow out from the water cup flushing outlet 144 to the flushing component, and then be sprayed onto the filtering assembly 12 to flush the filtering assembly 12; when it is necessary to execute the cleaning program for the tableware, the water distribution valve plate 145 opens the tableware flushing outlet, so that the tableware flushing outlet is communicated with the inlet. The water in the dishwasher can flow out from the tableware flushing outlet to the spray arm assembly, and then be sprayed onto the tableware to clean the tableware placed in the washing inner container.

[0055] Optionally, the flushing component includes a flushing ring 147 and a water connection pipe 146. The flushing ring 147 is sleeved on the outer periphery of the filtering assembly 12. Spray ports 1470 aligned with the filtering assembly 12 are formed on the inner side of the flushing ring 147. One end of the water connection pipe 146 is communicated with the water cup flushing outlet 144, and the other end is communicated with the flushing ring 147.

[0056] Optionally, a plurality of spray ports 1470 are provided. The plurality of spray ports 1470 are evenly distributed on the inner side of the flushing ring 147 to achieve uniform spraying and flushing of the filtering assembly 12.

[0057] Optionally, the diameter of the spray port 1470 gradually increases in the direction close to the filtering assembly 12, so that the water flow sprayed from the spray port 1470 can be sprayed onto the filtering assembly 12 in the up, middle, and down directions to further achieve uniform spraying and flushing of the filtering assembly 12. And because the water flow will flow downward under the action of gravity, in this embodiment, the flushing ring 147 is located above the filtering assembly 12, so that the sprayed water flow can flow through the filtering assembly 12 from top to bottom, improving the spraying and flushing effect on the filtering assembly 12.

[0058] Optionally, the tableware flushing outlet includes a first outlet 142 and a second outlet 143. The first outlet 142 is communicated with the lower spray arm of the spray arm assembly. The second outlet 143 is communicated with the middle spray arm and / or the top spray arm of the spray arm assembly.

[0059] Optionally, the upper part of the filtering component 12 protrudes upward from the opening of the water filtering cavity 10, so that the filtering component 12 can block part of the food residues on the upper side of the water cup body 11, avoiding excessive food residues from falling into the filtering cavity and causing blockage of the filtering cavity. At the same time, a double filtering effect on the washing water can be achieved, so that the washing water is first filtered once through the upper part of the filtering component 12 and then filtered a second time through the lower part of the filtering component 12, improving the filtering effect.

[0060] On the other hand, the present invention provides a dishwasher, including a washing inner container and the above-mentioned water cup structure 1.

[0061] Optionally, the chassis 2 of the washing inner container is inclined downward from the periphery to the middle, and the water cup structure 1 is installed in the middle of the chassis 2.

[0062] Optionally, it further includes a water inlet valve, a washing pump and a heating pipe. The heating pipe is used to heat the water in the washing inner container to facilitate efficient cleaning of tableware or the filtering component 12 and improve the cleaning effect. The water inlet valve is installed on the water inlet pipeline of the dishwasher to control the water inlet of the dishwasher. The washing pump is installed on the circulating water pipeline of the dishwasher to realize the circulating water spraying inside the dishwasher. The above-mentioned water inlet valve, washing pump and heating pipe are all prior arts and will not be elaborated here.

[0063] Please refer to Figure 7 , on yet another aspect, the present invention provides an operating method of the above-mentioned dishwasher, including the following steps:

[0064] S1: The dishwasher is on standby;

[0065] S2: Determine whether the water cup cleaning mode is selected. If so, open the water inlet valve of the dishwasher and then enter S3. If not, repeat S2;

[0066] S3: Determine whether L1≥L0. If so, it means that the water inflow has reached the preset flow rate. At this time, close the water inlet valve, turn on the ultrasonic module 13, start timing T1 and then enter S4. If not, repeat S3;

[0067] S4: Determine whether T1≥T01. If so, it means that the ultrasonic module 13 has generated enough micro-nano bubbles. At this time, close the ultrasonic module 13, adjust the flushing component 14 to open the water cup cleaning pipeline, turn on the washing pump and the heating pipe of the dishwasher, so that under the operation of the washing pump, the water in the dishwasher can spray hot water towards the filtering component 12 through the water cup cleaning pipeline, and at the same time start timing T2, and then enter S5. If not, repeat S4;

[0068] S5: Determine whether T2 ≥ T02. If so, it indicates that the flushing process of the filtration component 12 is completed. At this time, turn off the washing pump and the heating pipe, turn on the drain pump of the dishwasher and start timing T3, then enter S6. If not, repeat S5;

[0069] S6: Determine whether T3 ≥ T03. If so, it indicates that the water in the dishwasher is basically drained. At this time, end the program. If not, repeat S6;

[0070] Among them, L1 is the real-time water inflow, L0 is the preset water inflow, T1 is the real-time operation duration of the ultrasonic module 13, T0 is the preset operation duration of the ultrasonic module 13, T2 is the real-time operation duration of the washing pump and the heating pipe, T02 is the preset operation duration of the washing pump and the heating pipe, T3 is the real-time operation duration of the drain pump, and T03 is the preset operation duration of the drain pump.

[0071] Optionally, when L1 ≥ L0, the water in the dishwasher submerges the filtration component 12, so that the micro-nano bubble water can submerge the filtration component 12 and emulsify and decompose the dirt at various positions of the filtration component 12.

[0072] In an ordinary dishwasher, L1 can be selected as 1.2L. The amount of 1.2L of water can not only make the water on the chassis 2 submerge the filtration component 12, but also meet the requirements of the washing pump with a rotation speed of 2500r / min installed in an ordinary dishwasher (the rotation speed of the washing pump is 2500r / min, which can make the spraying force on the tableware and the filtration component 12 larger and meet the spraying force requirements).

[0073] Optionally, in S4, adjusting the flushing component 14 to open the water cup flushing pipeline includes the following steps:

[0074] Rotate the water distribution valve piece 145 of the flushing component 14 to make the water distribution valve piece 145 open the water cup flushing water outlet 144 of the flushing component 14, so that the water cup flushing water outlet 144 is communicated with the water inlet of the flushing component 14.

[0075] Optionally, 3min ≤ T1 ≤ 8min, and / or 3min ≤ T2 ≤ 8min, and / or 20s ≤ T3 ≤ 40s.

[0076] Exemplarily, in this embodiment, T1 = T2 = 5min, T3 = 30s.

[0077] The above are only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the inventive concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
