Embodiment Construction

[0009] Such as figure 1 , 2 As shown, a tensile water level sensor for a washing machine includes a housing 1 and an upper cover 2. There is a shaft 3 in the housing 1, and a steel wire rope 4 wound on the shaft 3 is used to give rotation power to the shaft 3, and one end of the steel wire rope 4 is fixed. On the shaft 3, the other end passes through the housing 1 and is limited by a riveting joint 5; the reverse return power of the shaft 3 relative to the wire rope is provided by a clockwork spring 6; during the rotation of the shaft 3, through the shaft 3 The vortex structure cam on the top converts the rotary motion into a linear motion through a transmission rod 7. There is a magnetic core 8 on the transmission rod 7. The left side of the magnetic core 8 is a spring 9 that allows the magnetic core 8 to compress the shaft 3. The spring 9 of the spring 9 On the left is an adjusting screw 10 that compresses the spring. The magnetic core 8 is covered with a plastic-encapsulat...

Abstract

The invention relates to a washing machine drawing water level sensor, belonging to the washing machine field. The invention is characterized in that: the housing is equipped with a shaft; the shaft has a wire rope winded thereon, a spring and a cam with vortex line structure; the shaft also has a transmission rod disposed on one side, which has a magnetic core; the magnetic core is equipped with coil on the periphery, and the coil has a inserting piece which is connected with the control panel of the washing machine. the invention can rotate the shaft to different angle by drawing the wire rope to different length; it also can drive the transmission rod with magnetic core to perform linear motion by the vortex line structure, thereby can change the relative position of the magnetic core in the coil, change the output frequency of the sensor, and realizes the judging controlling to the water level in the washing machine barrel. The invention is especially suitable for new environment-friendly type washing machine having no water between the inner and the outer barrel.

Description

technical field [0001] The invention belongs to washing machines, in particular to a washing machine tensile water level sensor. Background technique [0002] The water level sensor has compact structure, convenient control, and is widely used in various types of washing machines. As a standard universal part on the washing machine, the principle of the existing water level sensor is the same, and its principle structure is as follows: the washing machine washing tub is divided into an inner and outer cylinder, and there is an independent air chamber on the outer cylinder, which is connected with the water in the outer cylinder to maintain The water level is on the same plane; the upper end of the air chamber is connected to the air nozzle of the water level sensor through a sealed hose. When the water level of the inner tub of the washing machine changes, the water level in the independent air chamber on the outer cylinder also changes accordingly. Changes with the water ...
