Abstract

A pressure sensor comprises a pressure sensor body, wherein the pressure sensor body comprises a casing and a buckle, wherein a hydraulically sensitive deformable membrane is accommodated in the casing; the buckle is arranged at the top of the casing, buckle bodies and buckle wings are arranged on the buckle, and the buckle is detachably buckled and fixed with an electric appliance fixing rack. A first clamping foot and a second clamping foot on an elastic first arm and an elastic second arm are extruded and inserted into a hole of an electric appliance panel by means of the buckle and are firmly fixed through a first clamping wing and a second clamping wing on the outer side of the hole, so that the pressure sensor can be tightly hung on the panel and is convenient to mount and firmly fixed. The buckle can be pinched and extruded from outer sides of the first arm and the second arm and can be taken out of the hole of the panel when the width of the first clamping foot and the second clamping foot is smaller than the hole of the panel, and the pressure sensor is convenient and efficient to replace.

Description

technical field [0001] The invention relates to a pressure sensor, in particular to a pressure sensor connected to a water pool or a water collection box of a household appliance in use and used for detecting the water level of the water box. Background technique [0002] The present invention relates to an improved pressure sensor or pressure switch for detecting an operating parameter of a household appliance featuring a part that is movable relative to the carcass of the appliance itself, such as a washing machine, dryer or the like. Cylinder or pool of type machine. [0003] French patent application FR-A-2767194 describes a system for detecting some of these parameters using a liquid that is connected to the water supply system of the household appliance and integrally connected to the rotating basket containing the household appliance (washing machine or dryer). A pressure switch (pressure sensor) for closing the cylinder; it is known that the cylinder is connected to...
