一、发明实例 1“溢流洗菜盆”洗菜时,莱盆内盛满水后,莱都漂浮在水面上,由于自来水的冲击或水面的波动,菜极易被冲出盆外,不卫生又麻烦。在洗菜盆四周近口处钻1～3排小孔(如图),这样在洗菜时,水位到盆内打孔处时,就会自动溢出,而菜不会被冲出盆外。 I. Inventive Example 1 “Overflowing sinks” When washing dishes, the bowls are filled with water and Laidou floats on the water. Because of the impact of tap water or the fluctuation of the water surface, the vegetables can easily be washed out of the basin. Health is troublesome. Drill 1 to 3 rows of small holes near the wash basin (see the figure) so that when the vegetables are washed in the pot, the water level will automatically overflow and the vegetables will not be washed out of the pot.
