Embodiment 1

[0041] The present embodiment provides a kind of descaling agent, and it is prepared by following method:

[0042] 15g citric acid, 2.1g sodium carboxymethyl cellulose, 0.9g calcium carbonate and 12g sodium citrate are mixed homogeneously, and pressed with a pressure of 16MPa to obtain a spherical block descaling agent, the weight of the descaling agent is 30g, and the density 1.45g / cm 3 .

Embodiment 2

[0044] The present embodiment provides a kind of descaling agent, and it is prepared by following method:

[0045] Mix 18g malic acid, 2.1g hydroxyethyl cellulose, 2.4g calcium carbonate and 7.5g sodium nitrilotriacetate, and press with a pressure of 18MPa to obtain a spherical block descaling agent. The weight of the descaling agent is 30g, density 1.5g / cm 3 .

Embodiment 3

[0047] The present embodiment provides a kind of descaling agent, and it is prepared by following method:

[0048] 24g tartaric acid, 1.5g hydroxyethyl cellulose, 3g calcium carbonate and 1.5g sodium edetate are mixed uniformly, and pressed with a pressure of 15MPa to obtain a square block descaling agent, the weight of the descaling agent is 30g, The density is 1.4g / cm 3 .

Abstract

The invention provides a descaling agent, a preparation method thereof, a descaling device and a dish-washing machine. The organic acid, the cellulose ether and the slow-release agent in the descalingagent are matched with one another, so that the descaling agent has excellent water softening capacity and good slow-release performance, the descaling capacity of the descaling agent can be kept fora long time, and the descaling agent is suitable for softening and descaling flowing water; the descaling device comprises a storage unit used for containing a descaling agent, and a plurality of filter holes used for allowing the descaling agent to pass through are formed in the storage unit. The descaling device is arranged on the inner side of an opening-closing door of the dish-washing machine. In the washing process, the descaling agent is slowly dissolved and released through washing of water in the dish washing machine, and the descaling agent is discharged into the water from filter holes of the descaling device; organic acid in the descaling agent is gradually released, so that water softening and incrustation removing are achieved, and finally the problem that incrustation is generated in the long-term use process of the dish-washing machine is solved.

Description

technical field [0001] The invention relates to the field of dishwashers, in particular to a descaling agent, a preparation method thereof, a descaling device and a dishwasher. Background technique [0002] With the modernization of the kitchen, various advanced kitchen appliances have been developed and applied. Among them, household dishwashers are widely welcomed by people because of their good cleaning performance and convenient use. Judging from the current development situation, dishwashers may become a sales hotspot of new kitchen utensils after refrigerators, and the special detergents used in conjunction with them will also be further promoted and applied. The dishwasher uses high-temperature, high-pressure water jets to continuously wash the tableware surface at 360 degrees, and the special detergent decomposes the oil stains and residues on the tableware surface, and the hot water soaks and expands the food residues, so that the oil stains and residues quickly de...
