Embodiment 1

[0022] Such as figure 1 , 2 As shown, the three measurement ends and the common end 3 of this solution are installed on the same fixed plate 2, and the fixed plate is an L-shaped structure, wherein the long folded edge is installed on the outer surface of the outer tub 1 of the washing machine, and the short folded edge is installed on the outer surface of the washing machine outer tub 1. At the bottom of the outer barrel, the measuring end is installed on the long fold, and the common end is installed on the short fold. There are three measurement terminals, namely the drainage measurement terminal 4 installed at the bottom of the outer tub, the washing measurement terminal 5 installed at the bottom 4 / 5 upwards, and the overflow measurement terminal 6 installed at the top of the outer tub 20MM downwards. In order to prevent excessive washing water, the installation position needs to consider the influence of the rotation of the water flow during washing. The number of measu...

Embodiment 2

[0024] On the basis of Embodiment 1, the measuring end is installed in the fixed plate, and the fixed plate is formed by buckling and sealing two plates, and a slot parallel to the axis of the outer barrel is set on the inner wall of the outer barrel, and the fixed plate is inserted into the slot Inside, the fixed plate is located in the outer tub, and three through holes are set on the plate to expose the measuring point end of the measuring end. The wires of the three measuring ends are drawn from one end of the fixing plate to connect with the main control unit of the washing machine. Make a preventive seal between them to avoid water entering the fixed plate. This solution does not use destructive installation on the outer barrel, but only sets a concave or convex slot, which greatly reduces the volume, and is easier to maintain, and it is more convenient to seal the separate fixing plate.

[0025] The using method process of the present invention is as follows:

Abstract

The invention discloses a water-level measuring device for small / mini buoyancy washing machines and an application method thereof and relates to the field of washing machines. The water-level measuring device disclosed by the invention comprises a public end and a measuring end, wherein the measuring end is arranged on the side face of an external barrel of a washing machine, the public end is arranged at the bottom of the external barrel of the washing machine, and the public end and the measuring end are respectively connected with a master control unit of the washing machine by virtue of wires. According to the scheme of the invention, the public end is arranged at the bottom of the external barrel, and measuring points are arranged on the parts (at different heights) of the external barrel, so that by using the electric conduction character of water, when the contact points at different heights are contacted with water, the corresponding measuring end is conducted, and then according to the change in resistances between the measuring end and the public end, the current position of the washing water can be obtained. The measuring end and the public end can be arranged on a same fixed plate, so that the wire layout, installation and removal of the two ends are more convenient, and the occupied space of the measuring end can be further reduced. According to the scheme of the invention, because only one contact point contacted with water is required, the device disclosed by the invention is simple in structure, small in volume, low in cost and convenient to install, and does not require complicated processing devices and analysis programs.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a small / micro-buoyancy washing machine that utilizes changes in resistance caused by washing water to determine a water level measuring device and a usage method. Background technique [0002] The water level measuring device of the existing washing machine generally adopts the water level switch or water level sensor. Compared with the specified value, the current water level change of the washing machine can be obtained. The theory of the above method is that the water level change in the washing machine can be known at any time, and multiple washing programs and water level positions can be set, so that the washing machine has various working modes. However, the above-mentioned measuring devices all need corresponding sensing devices, so that the measuring devices themselves are bulky and difficult to shrink, and the cost is high. [0003] Among the types of washing machines,...
