A kind of overflow structure of dish-washing machine
Technical field
The utility model relates to a kind of novel overflow structure of dish-washing machine, belongs to the improvement technology of overflow protection structure.
Background technology
At present; The device of control washing pump inflow is to be positioned at the into flowmeter of water pipe end in the commercially available dish-washing machine, and after a certain amount of current advanced internal cavity of bowl washer, dish-washing machine was started working; In actual use; Regular meeting takes place owing to reasons such as flowmeter damages, and the water level that flows to inner bag can be higher than interior threshold, and water can overflow when opening the inside door of dish-washing machine so.Therefore; Commercially available dish-washing machine all is provided with excess flow protection device; And the excess flow protection device that most dish-washing machines use is a pressure switch, and this pressure switch is an electrical part, and not only cost is higher; And increased the weight of the difficulty of design program controller structure, also cause complete machine chassis structure more complicated simultaneously.
Summary of the invention
The purpose of the utility model is to consider the problems referred to above and provides a kind of dish-washing machine overflow reasonable in design, simple in structure, safe and reliable, lower-cost to protect structure.
The technical scheme of the utility model is: a kind of overflow mechanism of dish-washing machine; It is characterized in that comprising overflow cover, overflow nut, pad, overflow valve body and internal cavity of bowl washer; Its Intermediate gasket is sleeved on the pedestal of overflow valve body; The overflow valve body pierces in the installing hole on the bottom surface of internal cavity of bowl washer and screws with the overflow nut, on the end wall of overflow valve body spout hole is set, and the overflow cover spiral-lock at the top of overflow valve body and with the spout hole cover within it.
Said overflow cover apical cap inboard is provided with barrel mast type deck; The end wall of deck is provided with Ka Tai annular or that a plurality of circles are uniformly distributed with; Corresponding deck, the top of overflow valve body is provided with circular button hole, and deck is installed on realizes in the button hole that overflow cover is installed in the top of overflow valve body.
Said spout hole is provided with more than three isometrical and be uniformly distributed with.
Above-mentioned said overflow cover, overflow nut and overflow valve body are working of plastics; Pad is a rubber parts.
The utility model has adopted the excess flow protection device of crown cap structure, and parts not only simple in structure, required are few, and overall volume is little; Dismounting has easily significantly been saved the inner space of dish-washing machine, and need not to be electrically connected; Greatly reduce the difficulty of writing automatically controlled software, cost is low; And crown overflow cover can block the transmission of rocking of ripples in the dish-washing machine effectively, avoids because of the water surface rocks the illusion that causes overflow, can stop that bigger swill stops up spout hole simultaneously.

Fig. 3 is the complete section diagrammatic sketch of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Like Fig. 1, shown in 2; The overflow mechanism of the utility model dish-washing machine; Comprise overflow cover 1, overflow nut 2, pad 3, overflow valve body 4 and internal cavity of bowl washer 5, its Intermediate gasket 3 is sleeved on the pedestal 41 of overflow valve body 4, and overflow valve body 4 pierces in the installing hole 51 on the bottom surface of internal cavity of bowl washer 5 and screws with overflow nut 2; The end wall of overflow valve body 4 is provided with the isometrical and spout hole 42 that is uniformly distributed with more than three, and overflow cover 1 spiral-lock at the top of overflow valve body 4 and with spout hole 42 covers within it.
As shown in Figure 3; Said overflow cover 1 apical cap inboard is provided with barrel mast type deck 11; The end wall of deck 11 is provided with card platform 12 annular or that a plurality of circles are uniformly distributed with; Corresponding deck 11, the top of overflow valve body 4 is provided with circular button hole 43, and deck 11 is installed on realizes in the button hole 43 that overflow cover 1 is installed in the top of overflow valve body 4.
Be to practice thrift cost, above-mentioned said stream lid 1, overflow nut 2, overflow valve body 4 are working of plastics; Pad 3 is a rubber parts.
In the utility model dish-washing machine water inlet process, the water yield exceeds standard, and covers spout hole 42, and water will go down from the intermediate flow of overflow valve body 4, triggers warning device and reports to the police; When the water surface rocked or foam occurs, the crown type structure of overflow cover 1 can effectively stop water to cover spout hole 42, produced spurious alarm, also can stop that big swill stops up spout hole 42 simultaneously.
The utility model overflow infrastructure cost is low, and required parts are few, and are simple in structure, operates easy for installationly, need not to be electrically connected, and reduces the difficulty of writing automatically controlled software, and this overflow protection structural entity volume is little, saves the inner space of dish-washing machine.
