DETAILED DESCRIPTION

[0023] The following embodiments are used to illustrate the utility model, but the utility model is not limited by these embodiments. The specific embodiment of the utility model is modified or equivalent replacement is carried out to part technical features, and does not deviate from the spirit of the utility model scheme, and it should be covered in the technical scheme range that the utility model claims protection.

[0024] REFERENCE Figures 1-5The embodiment provides a dishwasher with an intelligent dispensing function, which comprises a dishwasher main body 1, a door body assembly 2, an intelligent dispensing assembly 3, a waterway system (not shown in the figure) and a main control assembly 4, wherein the dishwasher main body 1 is provided with a cavity 11 with one side opening. The door body assembly 2 is movably connected to the dishwasher main body 1 and used for opening or closing the cavity 11. In the embodiment, a door body detection sensor 21 is arranged on the dishwasher main body 1 or the door body assembly 2, and the door body detection sensor 21 is used for detecting whether the door body assembly 2 closes the cavity 11; in addition, a display operation panel 22 is arranged on the front upper end or the top of the door body assembly 2. The intelligent dispensing assembly 3 is arranged on the door body assembly 2 and comprises a washing liquid storage box 31, a peristaltic pump 32 and a washing liquid detection sensor 33, and a feeding opening 311 is arranged on the washing liquid storage box 31. The peristaltic pump 32 is arranged on the washing liquid storage box 31 and used for dispensing the washing liquid in the washing liquid storage box 31 into the cavity 11, so that the dishwasher has the intelligent dispensing function; the washing liquid detection sensor 33 is arranged on the bottom or the side wall of the washing liquid storage box 31 and used for detecting the residual amount of the washing liquid in the washing liquid storage box 31. The waterway system comprises a water inlet assembly and a water outlet assembly which are respectively connected to the cavity 11 of the dishwasher main body 1, the water inlet assembly comprises a water inlet valve and a water softener, and the water outlet assembly comprises a water outlet valve and a water outlet pump. The main control assembly 4 is arranged on the dishwasher main body 1 or the door body assembly 2, and the main control assembly 4 is electrically connected to the door body detection sensor 21, the display operation panel 22, the peristaltic pump 32, the washing liquid detection sensor 33, the water inlet assembly and the water outlet assembly.

[0025] When the dishwasher is powered on and enters a dishwashing program, the door body detection sensor 21 detects whether the door body assembly 2 is closed; after it is determined that the door body assembly 2 is closed, the water outlet assembly is first started to drain until the water in the dishwasher main body 1 is emptied and then the water inlet assembly is started to inject cleaning water into the dishwasher main body 1 until the water inlet assembly is closed after the set water level is reached; the washing liquid detection sensor 33 detects the residual amount X of the washing liquid in the washing liquid storage box 31, and the main control assembly 4 judges whether the residual amount X is not less than a target value, and if not, the user is reminded to add washing liquid, and if yes, the peristaltic pump 32 is started to run for a time t; after the peristaltic pump 32 is closed, a washing stage, a water draining stage and a drying stage are sequentially entered.

[0026] It can be seen that by detecting the remaining amount X of the washing liquid in the washing liquid storage box 31 before the water inlet is completed and the washing stage is entered, and determining whether the user needs to be reminded to add the washing liquid according to the size relationship between the remaining amount X and the target value, it can be avoided that the washing liquid is still in the wall-flow process in a short time after the door body assembly 2 is closed, which affects the judgment of the remaining amount X of the washing liquid, thereby causing misjudgment. This not only helps to improve the judgment accuracy of the remaining amount X of the washing liquid, but also can remind the user to add the washing liquid at one time when using the dishwasher, so as to automatically dispense in subsequent multiple dishwashing, reduce the frequency of the user adding the washing liquid, and less contact with the washing liquid to avoid skin corrosion.

[0027] Reference Figures 1-4 The feeding port 311 is arranged on the rear side wall of the washing liquid storage box 31 facing the cavity 11, so that the feeding port 311 faces upward after the door body assembly 2 is opened and laid flat, thereby achieving convenient feeding.

[0028] The peristaltic pump 32 is used for dispensing the washing liquid before washing. The working principle is that when the motor rotates all the time, the rotating disc with three balls rotates coaxially to extrude the washing liquid in the washing liquid delivery pipe into the cavity 11 of the dishwasher main body 1. According to the linear speed v of the outer diameter of the peristaltic pump 32, the rotation time t, the diameter d of the washing liquid delivery pipe, and the circumference π, the influence of the curvature of the washing liquid delivery pipe winding the rotating disc is ignored, and the volume capacity Lv of the dispensed washing liquid is calculated, wherein Among them, the running time t of the peristaltic pump 32 is tested by testing the samples of conventional tableware with different pollution degrees.

[0030] In the design stage, when the washing liquid storage box 31 does not store the washing liquid, the single-pass time t0 of the ultrasonic wave through the washing liquid storage box 31 is calculated. Since the wall thickness h0 of the washing liquid storage box 31 is known and the propagation speed of the ultrasonic wave in the washing liquid is c, the washing liquid level height h can be calculated according to the following formula: After the user uses for a period of time, the user uses different washing liquid, the ultrasonic wave propagation speed in the liquid can be different, so a group of calibration is applied to the conventional washing liquid on the market at the factory, and written in the main control component 4. When the user uses, if the detection is inaccurate, the washing liquid can be filled to the air, that is, the size of h is known, the calibration timing can be called, and the c value is corrected.
