Detergent and dish brightening agent are respectively put in the first storage cavity 6 and the second storage cavity 7 in the putting box 202 through the liquid putting port 9, liquid flows in through the storage cavities, when the first probe 301 and the second probe 302 in the air chamber 5 are switched on, the liquid level is higher than the low liquid level detection value, and when the third probe 13 in the first storage cavity 6 gives an alarm, the liquid in the first storage cavity 6 is in a high liquid level state, and the pouring of the liquid is stopped. If the first probe 301 and the second probe 302 in the gas chamber 5 are disconnected, the probes alarm, indicating that the liquid in the storage chamber is in a low liquid level state. The air chamber 5 is arranged in the storage container 2, the probe in the air chamber 5 is isolated from the liquid in the storage cavity, and the probe is prevented from being adhered by the poured liquid, so that the probe loses the liquid level detection effect. The probe judges whether the detergent and the dish brightening agent are at a low liquid level or a high liquid level by detecting the change of the volume value. The probes are mounted on the top, bottom or side walls of the reservoir 2, respectively. Because the detergent has certain viscosity, the liquid level detection can be disabled due to the wall hanging of the liquid. Therefore, a gas chamber 5 is designed, so that the probe is contacted with the detergent and the dish brightening agent at the lower end, and the probe is positioned in the gas chamber 5 at the top, so as to avoid the adhesion of the detergent and the dish brightening agent.

The utility model discloses a device is put in to detergent has solved the lot of current dish washer and has put in, can realize once putting in detergent and bright dish agent, gets into the dish washer inner bag through 4 drive fluid of measuring pump, realizes the measurement and puts in, avoids once pouring into too much detergent and bright dish agent and causes the waste. Due to the adoption of the automatic feeding function, when the dishwasher works, the detergent and the dish brightening agent can be automatically added, and when the detergent and the dish brightening agent are lower than a low liquid level, the probe can automatically detect and alarm in real time.

According to the utility model provides a further embodiment, the detergent is put in the device and is carried out liquid level detection accessible float switch and detect the detergent capacity change. Through throwing liquid mouth 9 and depositing chamber 6 and second and deposit chamber 7 and put in detergent and bright dish agent respectively to throwing in first in the box 202, liquid flows in through depositing the chamber, and first float 8 receives buoyancy effect rebound, and proximity switch 10 detects the float and apart from proximity switch 10's distance, and sensing signal judges the liquid level height of depositing the detergent in the chamber. The position of the second floater 14 in the storage cavity changes along with the amount of the poured liquid, the second floater 14 is positioned at the bottom of the storage cavity, the proximity switch 10 judges the distance from the second floater 14, the sensing signal judges that the second floater 14 is in a low liquid level state, and an alarm is given.

The utility model discloses a two embodiments can set up alone and deposit the chamber, also can set up jointly and deposit the chamber, ensure liquid level detection's accuracy.

It is to be understood that the present invention has been described with reference to certain embodiments, and that various changes or equivalents may be substituted for elements thereof by those skilled in the art without departing from the spirit and scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof.
