Specific embodiment
In order to be best understood from the purpose of the present invention, structure and function, with reference to the accompanying drawing, to a kind of liquid level of the invention
Detection device and dish-washing machine do further detailed description.
As shown in Figure 1, liquid level detection device of the invention, including water collection chamber 1 and baffle 2, baffle 2 are arranged in water collection chamber 1
Interior, the two sidewalls of baffle 2 are fixed on the inner wall of water collection chamber 1, and gap 3, baffle 2 is arranged in the bottom surface and 1 bottom surface of water collection chamber of baffle 2
Water collection chamber 1 is divided into the chamber of two connections, two chambers are respectively torus and test chamber, and the width of torus is greater than detection
The width of chamber, water collection chamber 1 constitute linker structure, and water outlet is arranged on the side wall of test chamber, and water outlet passes through connecting tube 4 and water
Position pressure switch 5 is connected to, and when liquid level rises in water collection chamber 1, the indoor liquid level of two chambers maintains an equal level, when liquid level reaches water outlet,
Liquid reaches water level pressure switch 5 so that the switching signal of water level pressure switch 5 changes by connecting tube 4.
Dish-washing machine in the process of work, generally includes the heat treatment process such as heating washing, heat drying, due to level pressure
4 diameter of connecting tube of switch 5 is small, in the detection process, since 1 internal-external temperature difference of water collection chamber is also easy to produce condensed water in connecting tube 4,
