Embodiment 1

[0022] Such as figure 1 , 2 As shown, the three measuring ends and the common end 3 of this solution are installed on the same fixing plate 2. The fixing plate is an L-shaped structure, in which the long folded edge is installed on the outer side of the washing machine tub 1, and the short folded edge is installed on the washing machine. At the bottom of the outer barrel, the measuring end is installed on the long flange, and the common end is installed on the short flange. There are three measuring terminals, namely the drainage measuring terminal 4 installed at the bottom of the outer tub, the washing measuring terminal 5 installed at 4 / 5 upwards from the bottom, the overflow measuring terminal 6 installed at the top of the outer bucket 20MM downward, and the overflow measuring terminal is used 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 measurement termi...

Embodiment 2

[0024] On the basis of the first embodiment, the measuring end is installed in the fixing plate. The fixing plate is made by buckling and sealing two plates. A slot parallel to the axis of the outer barrel is provided on the inner wall of the outer barrel, and the fixing plate is inserted into the slot Inside, the fixing plate is provided with three through holes on the plate in the outer tub, exposing the measuring point end of the measuring end. The wires of the three measuring ends are led out from one end of the fixing plate and connected to the main control unit of the washing machine. To prevent water from entering the fixed plate. This solution does not use destructive installation of the outer barrel, only provides a concave or convex slot, the volume is greatly reduced, and maintenance is easier, and it is more convenient to seal the separate fixing plate.

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

[0026] Step 1. The main control unit of the wash...

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, and in particular to a measuring device and a method of use for a small / micro buoyancy washing machine to judge the water level by using the change in resistance caused by washing water. Background technique [0002] Existing water level measuring devices of washing machines generally use water level switches or water level sensors, which mainly use the different effects of different water level pressures on the air chamber to drive contact switches or electromagnetic coils to act. The set value is compared to obtain the current water level change of the washing machine. The above method theory 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, which makes the washing machine work in a variety of ways. However, the above-mentioned measuring devices all require corresponding sensing devices, which makes the...
