Description

Cleaning equipment

Technical Field

The utility model relates to an electric appliance, in particular to cleaning equipment.

Background

In washing apparatuses such as dish washers, washing machines, shoe washers, etc., it is generally necessary to determine the degree of cleanliness of the articles by detecting the degree of contamination of the washing water to determine an optimal running program, washing time, etc. Among them, in the case of a dishwasher, a turbidity sensor is generally used to detect the degree of contamination of wash water. As disclosed in chinese utility model patent No. ZL201721604644.7 (grant publication No. CN 208435552U), a sump assembly of a dish washing machine and a dish washing machine having the same.

The sump assembly of the dish washing machine detects turbidity of the washing water by installing a turbidity sensor inside the circulating water cup. In order to protect the parts in the circulating water cup, the existing dish washer is generally provided with a filter screen at the top opening of the circulating water cup and a slag basket at the water outlet of the circulating water cup so as to filter the washing water, thereby avoiding a large amount of impurities from entering the inside of the circulating water cup. In this way, the turbidity sensor is used for detecting the washing water after filtering the impurities, so that the turbidity detection value of the turbidity sensor deviates from the actual value, and the detection result is not accurate enough.

The Chinese patent with patent number ZL202122117777.4 (issued publication number CN 215976487U) discloses a turbidity detection mechanism, which comprises a drain pipe, wherein the drain pipe comprises a first inner wall, a detection cavity is formed on the first inner wall, a first connector is arranged on the drain pipe, the first connector is provided with a second inner wall, a first interface is formed on the second inner wall, and the first interface is communicated with the detection cavity; the adapter is at least partially arranged at the first interface, is provided with a third inner wall, forms a second interface communicated with the detection cavity and is provided with a first connecting structure; and the turbidity sensor is at least partially arranged at the second interface, and is provided with a second connecting structure which is detachably connected with the first connecting structure.

According to the turbidity detection mechanism, the turbidity sensor is arranged on the drain pipe, and all washing water is finally discharged through the drain pipe, so that the turbidity sensor can detect an actual turbidity value, and the detection result is more accurate.

In addition, the working principle of the turbidity sensor is as follows: the sensor is internally provided with an infrared light emitting end and an infrared light receiving end, when light rays emitted by the infrared light emitting end pass through a certain amount of water, the transmission amount of the light rays depends on the pollution degree of the water, and the more polluted the water is, the less light rays are transmitted. The infrared light receiving end converts the transmitted light intensity into corresponding current, the transmitted light is more, the current is more, and conversely, the transmitted light is less, and the current is less. Further, by measuring the magnitude of the infrared light receiving end current, the degree of water fouling can be calculated. However, many bubbles are easily formed in the water flow, and the presence of bubbles affects the light transmission amount, and thus the detection accuracy of the turbidity sensor.
