A kind of draining control structure of dish-washing machine
Technical field
The utility model is a kind of draining control structure of dish-washing machine, belongs to the renovation technique of the draining control structure of dish-washing machine.
Background technology
After the dish-washing machine of prior art washes tableware, need the water in a period of time emptying water tumbler, emptying time is by the programme-control that sets, for the water in the water tumbler is drained only, generally longer water discharge time can be set, therefore, empty draining phenomenon can appear in the water in draining in the smooth and easy or water tumbler more after a little while, increase the working time of draining pump like this, reduced the service life of draining pump, increased energy consumption and noise.
The utility model content
The purpose of this utility model is to consider the problems referred to above and a kind of water discharge time of can accurately controlling is provided, and reduces energy consumption and noise, improves the draining control structure of the dish-washing machine in service life.
The technical solution of the utility model is: a kind of draining control structure of dish-washing machine, comprise water tumbler and draining pump, it is characterized in that also comprising air chamber, pressure sensor, control panel and wireway, wherein air chamber is communicated with the bottom of water tumbler, wireway one end is communicated with air chamber, the other end is connected with pressure sensor, and pressure sensor is electrically connected with control panel, and control panel is electrically connected with draining pump by lead.
The utility model is because the air chamber that adopts setting to be communicated with the water tumbler bottom, pressure sensor is communicated with air chamber, the structure that pressure sensor and draining pump are electrically connected with control panel, therefore, can accurately control water discharge time, eliminate sky row's time of draining pump, reduce energy consumption and noise, reduce the working time of draining pump, prolonged the service life of draining pump greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Embodiment:
Structural representation of the present utility model as shown in Figure 1, comprise water tumbler 1, draining pump 5, air chamber 2, pressure sensor 3, control panel 4 and wireway 6, wherein air chamber 2 is communicated with the bottom of water tumbler 1, wireway 6 one ends are communicated with air chamber 2, the other end is connected with pressure sensor 3, pressure sensor 3 is electrically connected with control panel 4, and control panel 4 is electrically connected with draining pump 5 by lead.
When the utility model draining pump is started working, water begins to discharge, water level in the water tumbler descends, the pressure of the air chamber that is communicated with the water tumbler bottom reduces gradually, pressure sensor is the real-time height of water level in the water tumbler by the pressure size of wireway perception air chamber, when the pressure of air chamber reduced to the value of setting, pressure sensor offered control panel by lead with information, and control panel stops draining by the control draining pump.
