液位测量仪包括水位传感器10,所述水位传感器10固定在所述储水箱11的底部,通过重量变化感应出储水箱11中液位高度。The liquid level measuring instrument includes a water level sensor 10 which is fixed at the bottom of the water storage tank 11 and senses the height of the liquid level in the water storage tank 11 through weight changes.
本申请实施例还提供一种洗碗机,包括上述的干燥装置,其中循环风道19为竖直设置,其上端入口与洗碗机内胆2上部连通,下端出口与洗碗机内胆2下部连通,在循环风道19的出口端设置风机13。The embodiment of the present application also provides a dishwasher, including the above-mentioned drying device, wherein the circulating air duct 19 is vertically arranged, the upper end of the inlet is communicated with the upper part of the dishwasher liner 2, and the lower end of the outlet is connected with the dishwasher liner 2 The lower part is connected, and a fan 13 is provided at the outlet end of the circulating air duct 19.
在洗碗机内胆2内设有上喷淋臂1和下喷淋臂3,对放置在洗碗机内胆2中的碗碟喷淋清洗,喷淋水(由其它水源提供,图中未画出入水管)事先经洗涤泵4加压及加热器5加热后,送入至洗碗机内胆2,喷淋冲洗后的水可循环使用,或经排水泵8由排水管7排出。An upper spray arm 1 and a lower spray arm 3 are provided in the dishwasher liner 2 to spray and clean the dishes placed in the dishwasher liner 2 with spray water (provided by other water sources, as shown in the figure). (The water inlet pipe is not drawn). After being pressurized by the washing pump 4 and heated by the heater 5, it is sent to the inner tank 2 of the dishwasher. The water after spraying and washing can be recycled or discharged from the drain pipe 7 through the drain pump 8. .
当洗碗机喷淋洗涤结束后,洗碗机内胆2内部湿热空气和水分多,此时洗碗机进入干燥阶段,风机13开始转动,将循环风道19中的空气往洗碗机内胆2中输送,循环风道19中形成空气负压,将洗碗机内胆2中的湿热空气吸入循环风道19,同时热泵单元开始工作,蒸发器18产生冷量,将经过蒸发器18的湿热空气迅速冷凝,经过蒸发器18冷凝的空气变成了干冷空气,再经过冷凝器加热,送回洗碗机内胆2中,将内胆2中的水分再次蒸发,再吸入循环风道,如此循环达到干燥效果。When the spray washing of the dishwasher is finished, the hot and humid air and moisture in the inner liner 2 of the dishwasher are high. At this time, the dishwasher enters the drying stage, and the fan 13 starts to rotate, and the air in the circulating air duct 19 is sent into the dishwasher The air is conveyed in the tank 2, and negative air pressure is formed in the circulating air duct 19, and the hot and humid air in the dishwasher liner 2 is sucked into the circulating air duct 19. At the same time, the heat pump unit starts to work. The evaporator 18 produces cold energy and passes through the evaporator 18. The hot and humid air rapidly condenses, and the air condensed by the evaporator 18 becomes dry and cold air. It is heated by the condenser and sent back to the dishwasher liner 2 to evaporate the moisture in the liner 2 again and then suck it into the circulating air duct. , This cycle achieves the drying effect.
经过蒸发器18的湿热空气迅速冷凝,产生的冷凝水顺应重力流入接水槽17中,经过接水槽17底部的导流管15流入储水箱11中,储水箱11中的冷凝水再通过排水泵9经过 排水管7排出洗碗机。The hot and humid air passing through the evaporator 18 quickly condenses, and the generated condensate flows into the water receiving tank 17 according to gravity, and flows into the water storage tank 11 through the diversion pipe 15 at the bottom of the water receiving tank 17, and the condensed water in the water storage tank 11 passes through the drain pump 9 Drain the dishwasher through the drain pipe 7.
储水箱11底部或侧面有水位传感器10,用于在干燥阶段检测储水箱11中的储水量,当干燥程序开始后,水位传感器10检测储水箱11的水位值H1,控制器6记录该值,热泵组件及风机开启预设时间S1,运行过时间S1后,水位传感器10检测该时刻储水箱11中的水位并记录为H2,判断H2-H1>预设值X1?若是则返回“检测水位值H1”,若否,则程序结束。通过此方法间接地检测到洗碗机内部的干燥程度,从而改变运行时长,达到干燥效果好及节约能耗的问题。There is a water level sensor 10 at the bottom or side of the water storage tank 11, which is used to detect the amount of water stored in the water storage tank 11 during the drying phase. When the drying process starts, the water level sensor 10 detects the water level value H1 of the water storage tank 11, and the controller 6 records this value. The heat pump components and fans are turned on for the preset time S1. After the running time S1, the water level sensor 10 detects the water level in the water storage tank 11 at that moment and records it as H2, and judges H2-H1>the preset value X1? If yes, return to "detect water level value H1", if no, then the program ends. Through this method, the degree of dryness inside the dishwasher can be detected indirectly, so as to change the running time and achieve the problem of good drying effect and energy saving.
