Control method of sink type cleaner

Abstract

The invention discloses a control method of a sink type cleaner. The method includes the following steps that a water quality hardness sensor detects the hardness of water, a controller compares the detected hardness value of the water with a built-in set value, and when the detected water hardness value is larger than the set value, the controller controls a reversing valve to change the direction of water flow and make the water flow pass through a resin cavity and then flow out of a water softener device, otherwise the controller controls the reversing valve to change the direction of the water flow and make the water flow enter the water softener device from a water inlet of the water softener device and then directly flow out of a water outlet of the water softener device; when the water flow passes through the resin cavity and then flows out of the water softener device, the controller records and accumulates the water flow detected by a flow meter at the same time, when the accumulated water flow is larger than a set value, a replacement and regeneration program is started, the reversing valve is controlled to change the direction of the water flow during the next time of water input, and the water flow passes through a saline cavity and the resin cavity and finally flows out of the water softener device. By means of the method, whether the water is subjected to softening treatment or not can be automatically controlled, the cleaning time is effectively shortened, and resources are saved.

Description

technical field [0001] The invention relates to the field of kitchen utensils, in particular to a control method for a sink type washing machine. Background technique [0002] A sink type washing machine is an integrated home appliance that has the function of a sink and can automatically clean tableware, fruits and vegetables, seafood, etc. Usually, when washing tableware, the water is heated to about 70°C. At this time, if the hardness of the water exceeds 60ppm, it is easy to form scale on the inner wall of the washing machine and the surface of electrical components. With the accumulation of scale, it will seriously affect the cleaning performance. [0003] The water softener uses the resin to absorb calcium and magnesium ions in the water to soften the water quality and avoid scaling; at the same time, it can also use the sodium ions in the brine to replace and regenerate the resin, and the softening and regeneration process can be repeated. [0004] Common sink cleani...

Chinese Patent Publication Nos. CN106963318A and CN107334443A all provide water softeners with compact structure, flat shape and small volume, which can be used for configuration and use of sink type washing machines. The cleaning water flows through the resin softening treatment, that is, every time the water needs to be softened before it flows into the cleaning tank of the sink type cleaning machine, which increases the cleaning time and reduces the life of the resin, resulting in waste of resources
