The ratio of the hole area ranges from 2.5 to 56.5. If the ratio is too large, it may directly cause the opening to be too large, and indirectly cause the volume of the water chamber and the entire water tank to be too large. If the ratio is too small, the opening may be too small if the through-hole area of the side hole is constant, and it is not easy to clean the sundries inside the lower water chamber, and the water flow into the lower water chamber is not enough. Can quickly enter the cycle. Preferably, the openings, side holes, and drains are all circular holes, and the ratio of the opening diameter D1 to the side hole diameter D2 ranges from 1.6 to 7.5, and the ratio of the opening diameter D1 to the drain diameter D3 The range is 1.3~3.7. Specifically, the opening diameter D1 ranges from 80 mm to 150 mm, the side hole diameter D2 ranges from 20 mm to 50 mm, and the height H of the drain chamber ranges from 80 mm to 160 mm.

In addition, the bottom of the upper cover 2 is also provided with a movably connected spray arm 21, the spray arm 21 can rotate and spray the accommodating cavity under the drive of water flow, and the spray arm 21 and the side The hole 33 is in fluid communication with the pipeline, and is driven by the water pump 4 provided on the pipeline to form a circulating waterway with the accommodating cavity.

Rotate under force to perform periodic and all-round spray washing on dishes, chopsticks or fruits and vegetables. With the upper spraying structure, the water jetted downwards can generate a large flushing force under the action of water pressure and gravity, which can quickly wash away oil, food residues or sediment, preventing them Adhering to the upper surface of tableware, fruits and vegetables or the inner cavity of the sink, causing secondary pollution.

As shown in Fig. 2, Fig. 3 and Fig. 4, specifically, the drainer 3 also includes a casing 35, a valve body 34, and a driving device, and the valves 34 include a guide rod 341 and a valve body 342, and the inner The bottom of the cavity is provided with a central hole 36 and a water hole 37, and the lower end of the guide rod 341 can move in the center hole 36. When the valve closes the aforementioned water outlet, the valve body 342 covers and seals the water hole 37. At this time, the circulating waterway is a closed loop. The drive device includes a motor (not shown in the figure) and a drive member 38 connected thereto, and the drive member 38 is driven to rotate through the direct output of the motor. When working, the motor drives the driving member 38 to rotate and push against the bottom of the guide rod 341, so that the valve body 34 moves upward in the lower water chamber 31, and the valve body 342 is far away from the water hole 37 to realize drainage. After the drainage is completed, the driving member 38 resets, and the valve body 34 falls under the effect of its own gravity and reseals the water hole 37. In addition, in normal use, the upper end of the lifting guide rod 341 can also be manually moved to perform manual drainage, so as to meet abnormal practical needs.

The gap formed between the holes passes through into the lower water 31 cavity and is discharged from the water outlet 32 .

Further, the side hole is also provided with a second filter screen 331, the mesh area of the second filter screen 331 is smaller than the mesh area of the first filter screen, further filtering out the leakage from the first filter screen. Small silt residue prevents it from entering the circulation pipeline and causing blockage. In addition, the ratio range of the water passage area S1' of the first filter 343 to the water passage area S2' of the second filter is 2~1. If the ratio is too large, the water flow entering the lower water chamber will It cannot enter the circulation quickly, which will affect the circulation efficiency and cause the cleaning effect to deteriorate.

Preferably, the meshes of the first and second filter screens are circular, and the diameter of the mesh holes of the first filter screen is larger than that of the second filter screen. Specifically, the mesh diameters of the first and second filter screens are both in the range of 0.8 to 2 mm. If the mesh diameter is too large, it is easy to cause relatively large particles of sediment to enter the water chamber, which is likely to cause blockage of the circulation pipeline; If it is too small, the mesh will be easily blocked by sediment or other debris, and the water in the tank will not be able to enter the circulation pipeline in time for circulation, which will affect the cleaning effect.

Further, in order to prevent the small sediment residues leaked from the first filter screen 343 and excluded by the second filter screen 331 from accumulating at the bottom of the lower water cavity and blocking the circulating water hole, the side hole 33 is higher than the bottom of the lower water cavity. bottom surface. Preferably, the ratio of the distance h between the lowest point of the side hole and the opening to the height H of the lower water chamber is in the range of 0.5-0.9.

By setting the first and second filter nets, the sundries are filtered in two stages, so as to prevent the larger grains of sundries from entering the circulation pipeline and causing the pipeline or the spray port on the spray arm to be blocked, which will affect the cleaning effect and The overall reliability of the machine.

As shown in FIG. 2 , FIG. 3 , and FIG. 5 , the circulating waterway is also provided with a heating device 39 for heating the water flow in the circulating waterway. The heating device 39 can be thick film heating, electromagnetic heating, or heating tube heating. Preferably, a heating tube is used for heating, and a heating tube matching the external shape of the water cavity is fixed outside the lower water cavity by welding or other methods, and convection The water flow through the lower water chamber is heated. By directly installing the heating pipe on the drain, the length of the connecting pipeline is reduced, the structure of the entire circulation pipeline is more compact, and the space of the drain chamber is larger, the heat transfer of the heating pipe is faster, and the heating effect is good.

In addition, as shown in FIG. 1 , an ultrasonic device 7 is provided on the outer bottom of the accommodating cavity. Preferably, the number of the ultrasonic devices 7 is 3 to 8, and the water in the water tank produces a cavitation effect through the action of the ultrasonic wave, and the force generated by the cavitation effect enables impurities such as grease, residue, and silt to be removed from the water quickly. The surface of the sticky object falls off, so as to achieve the purpose of cleaning. In addition, the ultrasonic device is arranged at the bottom, which can ensure a good cleaning effect even when the water level in the storage chamber is low.

As shown in Fig. 2, Fig. 6, Fig. 7 and Fig. 8, an electrolytic water device 8 is connected to the pipeline between the spray arm and the drain. Hydroxyl radicals produced by electrolyzed water can effectively sterilize, remove pesticide residues, remove odors, sterilize tableware, fruits and vegetables, sinks, and the waterways and equipment involved, remove pesticide residues, and keep the smell fresh and odor-free for a long time. Further, a one-way valve 9 is provided on the pipeline between the water pump and the spray arm, and the one-way valve 9 is opened in the direction toward the spray arm, and the water inlet is arranged between the spray arm and the one-way valve. Between the two-way valves, so that during the initial spraying (no circulation), the one-way valve is closed, and the water flow can only flow from the water inlet to the spray arm in the circulation pipeline. Optionally, as shown in Figures 7 and 8, the electrolysis device 8 is connected in series with the one-way valve 9, and the electrolysis device 8 is arranged between the one-way valve 9 and the water pump. Preferably, as shown in FIG. 6 , the electrolyzed water device 8 is connected in parallel with the one-way valve 9 , such a structure can simultaneously ensure the efficiency of spraying and the working efficiency of the electrolyzed water device.

Further, a temperature sensor (not shown in the figure) and a water level sensor (not shown in the figure) are respectively provided in the circulating water circuit, the temperature sensor detects the water temperature in the circulating pipeline, and controls the heating power of the heating device 39 or Start and stop, adjust the water temperature in real time. The water level sensor can be arranged on the drainer 3 or the tank main body 1 to control the water level in the accommodating chamber.

The cleaning method of described intelligent sink comprises the steps:

S10: Pre-cleaning, start the water inlet, the water flow from the water inlet passes through the spray arm and then spray the items in the storage chamber, after the cleaning is completed, open the valve to drain water;

S20: Intensify cleaning, close the valve, start the ultrasonic device and/or electrolyzed water device, drive the water flow in the circulating waterway through the water pump to perform circular spray cleaning, and open the valve to drain water after cleaning.

S30: post-processing, repeating step S10 and then ending the cleaning.

Optionally, in the step S30, keep the valve open after repeating the step S10, that is, in the case of non-intelligent cleaning of the water tank, the valve of the water tank is in a normally open state.

Preferably, in the step S10, opening the valve at the bottom of the lower water chamber is further included before the water enters, and in the step S30, after repeating the step S10, the cleaning further includes closing the valve at the bottom of the lower water chamber. This is to prevent the peculiar smell in the downpipe from entering the kitchen through the drain.

First, through pre-cleaning, the food residue and sediment adhering to the surface of the tableware or fruits and vegetables are washed down and discharged out of the sink with the water flow, and then through ultrasonic and/or electrolytic water devices, the adhesion to the surface of the tableware or fruits and vegetables is stronger Remove the oil or pesticide residues, etc., and finally repeat step S10 for the final spray cleaning to ensure that the dishes, chopsticks or fruits and vegetables are completely cleaned.

In the step S20,

Optionally, only the ultrasonic device or the electrolytic water device is activated.

Optionally, the ultrasonic device and the electrolytic water device are used at the same time, and the ultrasonic device is started before the electrolytic water device.

Preferably, the ultrasonic device and the electrolytic water device are used at the same time, and the ultrasonic device and the electrolytic water device are started simultaneously. The advantage of this is that the ultrasonic wave can release the bacteria on the surface of the object into the water faster under the action of cavitation, and then use the hydroxyl radicals generated in the water by the electrolytic water device to kill the bacteria in the water, which can significantly improve the sterilization Efficiency, to ensure the cleaning effect, but because the electrolysis effect of the electrolytic water device is slow, so the ultrasonic device and the electrolytic water device are started at the same time, and the time difference between the working efficiency of the two devices can be used to ensure the cleaning effect. Reduce the total cleaning time, reduce the waiting time of consumers, and improve the user experience of consumers.

Further, the step S20 also includes a step S21: start the heating device, and circulate and heat the water flowing through the lower water chamber, and the heated water temperature ranges from 15°C to 70°C.

It can be understood that step S21 is mainly applied in the cleaning process of bowls and chopsticks. This is because the use of hot water at a higher temperature melts oils with a lower melting point and separates them from the surface of the bowls and chopsticks. The irregular movement and diffusion of molecules is faster, and it is easier to diffuse into the dirty things to loosen them and clean them.

Of course, the step S21 can also be applied in the fruit and vegetable cleaning process, especially in the north or winter, heating the low-temperature water to normal temperature, so that the fruits and vegetables can be cleaned more cleanly.

Further, for cleaning the dishes, the step S20 includes two stages. In the first stage, after the valve is closed, the water enters and the heating device and the ultrasonic device are activated, and the valve is opened to drain water after circulating spray cleaning. Remove the oil stains on the bowls and chopsticks and the residual impurities still adhering after step S10. In the second stage, close the valve, enter water and start the heating device, ultrasonic device and electrolytic water device. Through the connection and cooperation between the three sets of devices, the dishes and chopsticks are sprayed and cleaned in a circular manner. After completion, the valve is opened to drain water. The main function is to further remove Oil stains are sterilized and deodorized.

For washing fruits and vegetables, first judge the water temperature. If the water temperature is significantly lower than normal temperature, start the heating device, ultrasonic device and electrolytic water device after the water starts to enter. The heating device stops heating after heating the water temperature to normal temperature. The device works together to clean the fruits and vegetables.

It should be noted that the operating temperature of the electrolyzed water device should not exceed 40°C, otherwise, the electrolysis efficiency, sterilization and deodorization of the electrolyzed water device will be reduced, and the device may even be damaged. The working temperature of the ultrasonic device should not exceed 70°C, otherwise it may cause damage to the ultrasonic device. Therefore, in the actual use process, while satisfying the overall function, it is also necessary to cooperate with the heating device, the ultrasonic device, the working sequence and working time setting of the electrolytic water device.

Further, in order to improve cleaning efficiency, the step S20 further includes a step S22: adding a cleaning agent before the water flow is circulated or at an early stage of the cycle. It should be noted that the cleaning agent can be ordinary detergent or fruit and vegetable cleaning liquid, and does not need a special cleaning liquid. During use, a large amount of foam will be generated due to the action of the cleaning agent. Too much foam will easily lead to insufficient driving force of the spray arm, resulting in poor spray effect. Therefore, combined with the above-mentioned upper spray structure, it can defoam the large amount of foam generated in the accommodating cavity during the cleaning process, thereby reducing the problem of insufficient power of the spray arm caused by the influence of foam on the circulation pipeline, thus eliminating the need for It solves the problem that consumers need to purchase special cleaning fluid, reduces the use cost of consumers, and improves the convenience of use at the same time.

Specifically, the cleaning method mainly includes the following working processes:

Remove food residues: Open the valve, tap water will spray from the spray arm on the upper cover and push the spray arm to rotate. After the water is sprayed from top to bottom for a certain period of time, the food residue in the dishes or the sediment on the fruits and vegetables will be removed. Washed down by the water flow and discharged from the drain port 32 of the drainer 3, this process is mainly used for cleaning in the early or late stages.

Washing and spraying: close the valve, tap water is sprayed from the spray arm and after the target water level is detected by the water level sensor, the tap water valve is closed, and the heating device 39 is turned on at the same time to heat the water in the tank, and then the water pump 4 is turned on, the water in the tank After pressurization, it is sprayed downwards by the spray arm 21, sprays and washes the tableware, and stops heating when the temperature sensor detects that the water temperature reaches the required temperature. This process is mainly used for mid-term cleaning.

Sterilization, deodorization, and household medicine residue removal: close the valve, tap water is sprayed from the spray arm and the target water level is detected by the water level sensor, stop the water intake, turn on the water pump 4, and the water in the tank is pressurized and then flows from the spray arm to the water tank. Spray down, spray and rinse the tableware. Specifically, use ultrasonic device and electrolytic water device to release the bacteria on the surface of the object into the water through ultrasonic waves, and then use the hydroxyl radicals generated by the water catalyst to sterilize the bacteria. This process is mainly used for Cleansing medium.
