Description of drawings
Fig. 1 is the oblique view of the dish-washing machine tank in the specific embodiment of the invention;
Fig. 2 is the oblique view of another angle of the dish-washing machine tank in the above-mentioned embodiment.
The specific embodiment
Shown in Figure 1 is the oblique view of the dish-washing machine tank in this embodiment; Fig. 2 is the oblique view of another angle of this tank.
This dish-washing machine tank 1 is arranged on the bottom of dish-washing machine (not shown), is used to collect the water that cleaned behind the tableware.In tank 1, be formed with groove 2, form porosely 6 in this groove 2, turbidity transducer (not shown) is installed in this hole 6, and this turbidity transducer is projected in this groove 2 from this hole 6.
In tank 1, be formed with and be used to install the cylindric projection 3 of spray thrower (not shown) (spray thrower seat under constituting) down.One water pump (not shown) is communicated with the bottom of this tank 1 from the outside of tank 1; Thereby the water of collecting in the tank 1 is extracted out; And; The delivery port of this water pump passes the wall portion (being exactly in cylindric projection 3 radially inner side positions specifically) of tank 1 via pipeline (not shown) and is communicated with following spray thrower, has constituted the water channel that following spray thrower is supplied water by this pipeline, by this water pump spray thrower is supplied water to spray thrower with certain hydraulic pressure.In other words, this water channel is positioned at the radially inner side of cylindric projection 3.
As shown in the figure, on the sidewall of cylindric projection 3, be formed with gap 4.In addition, on the inwall of tank 1, be formed with diversion passage 5, in this embodiment, this diversion passage forms through on the inwall of tank 1, forming a straight groove.One end of this diversion passage 5 is in the sidewall upper shed of groove 2 and be communicated with this groove 2, and the gap 4 that forms on the sidewall of the other end and cylindric projection 3 is communicated with.On to the water channel that spray thrower supplies water down, be formed with opening (side opening; Not shown); Diversion passage 5 is communicated with water channel with this opening through gap 4; When in water channel, having water pump to supply water, a part of water that is flowing in the water channel can flow to tank 2 via this opening, gap 4, diversion passage 5, and the turbidity transducer in the tank 2 is washed.So, turbidity transducer is kept clean, thereby guarantee its accuracy of detection.
In addition, in this embodiment, sensor is positioned at current the place ahead of diversion passage, and the higher position is unlikely to be submerged in the water so always, simultaneously dirtyly generally is deposited on the bottom, so the position leans on upward, more is difficult for being infected with dirty; In addition, be to have certain flow velocity to the water in the water channel of spray thrower water supply down, thereby can make the flushing current of flushing sensor also have certain flow velocity, thereby can wash sensor effectively; Owing to can realize the flushing of sensor like this, thereby need not extra artificial the cleaning; In addition, because be accompanied by the carrying out of washing procedure, the sustainable water source that provides of spray thrower post cleans, so scavenging period is long; Moreover, because the water in the tank along with the variation of program, can in time be got rid of, be installed in the turbidity transducer in bottom of gullet and the washing pump chamber with respect to those, do not worry being embedded in the water for a long time.
The above is merely preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.That is, can in the scope that does not break away from purport spirit of the present invention, carry out suitable change to above-mentioned embodiment.
For example, in the above-described embodiment, be that example is illustrated with the turbidity transducer, yet, be not limited to this, sensor of the present invention can be turbidity transducer, temperature sensor, level sensor or they any two or overall integrated.
In addition, in the above-described embodiment, on cylindric projection 3, offer gap 4 and realization connection diversion passage 5 and spray thrower water channel, but be not limited to this, for example also can just on the sidewall of cylindric projection 3, opening be set.In the above-described embodiment, constitute water channel by the pipeline of the radially inner side of cylindric projection 3, but also can directly constitute water channel by this cylindric projection 3.
In addition; In the above-described embodiment, through offering on the inwall of tank 1 that gutter 5 forms the diversion passage and the water in the water channel that will supply water to spray thrower down guided sensor into, yet; Be not limited in this; For example, can constitute the diversion passage of the water in the water channel being guided into sensor by this pipeline at the pipeline that an open communication on the sidewall with water channel is installed on the tank.In addition, the water channel that is utilized also is not limited to the passage to following spray thrower water supply, for example also can be the passage that other spray throwers are supplied water.
In addition, in the above-described embodiment, water channel passes the wall portion of tank 1 and following spray thrower is supplied water, yet, also be not limited to this, also can be for only realizing water supply via other positions.
