Detailed Description
The present invention is illustrated by the following examples, but the present invention is not limited to these examples. Modifications to the embodiments of the invention or equivalent substitutions of parts of technical features without departing from the spirit of the invention are intended to be covered by the scope of the claims of the invention.
Referring to fig. 1 to 5, the present invention provides an overflow preventing structure of a dish washer, including a first overflow detecting device, which includes an overflow tank 41, a communicating pipe 42 and a probe structure. The overflow groove 41 is provided on the base 1 of the dishwasher, and the top of the overflow groove 41 is higher than the highest water level of the cup 3 of the dishwasher. One end of the communication pipe 42 is communicated with the overflow tank 41 and the other end is communicated with the cup 3 of the dishwasher. The probe structure is arranged on the wall of the overflow tank 41, and when the water in the overflow tank 41 rises to be in contact with the probe structure, the probe structure is communicated with a controller of the dish washing machine to form a loop.
According to the water overflow preventing structure of the dish washing machine, the overflow groove 41 is arranged on the base 1, the communicating pipe 42 is arranged to communicate the overflow groove 41 with the water cup 3, so that when the water level in the water cup 3 rises according to the principle of a communicating vessel, the water level in the overflow groove 41 also rises synchronously, and then the probe structure is adopted to detect the water level in the overflow groove 41, so that the actual water level in the water cup 3 can be accurately detected. Specifically, when the water in the overflow groove 41 rises to be in contact with the probe structure, the probe structure is communicated, so that the probe structure is communicated with the controller to form a loop, the controller obtains a signal overflow signal, and then instructs the dishwasher to stop water inflow, and/or pump out the water in the water cup 3, and/or gives an alarm, so that the overflow problem of the dishwasher is automatically detected and solved.
Optionally, the probe structure includes a support 44 and two probe bodies 43. The holder 44 is mounted on the overflow tank 41. The two probe bodies 43 are arranged on the support 44 and extend into the overflow groove 41, the bottom end of the probe body 43 is higher than the highest water level of the water cup 3, and when the water level in the overflow groove 41 rises to be in contact with the probe bodies 43, the two probe bodies 43 are communicated with each other and form a loop with the controller.
Optionally, the probe structure further comprises a lead 45, and the two probe bodies 43 are electrically connected with the controller through the lead 45.
Optionally, the base further comprises an overflow channel 46 and an overflow port 461 arranged at the upper end of the overflow channel 46, the overflow channel 46 is communicated with the bottom cover 11 arranged on the base 1, the height of the bottom end of the overflow port 461 is lower than the height of the top end of the overflow groove 41, and the height of the bottom end of the overflow port 461 is higher than the height of the bottom end of the probe body 43. So that when the probe structure is abnormal, and the water in the overflow groove 41 continues to rise after contacting the probe body 43, the water in the overflow groove 41 can flow into the overflow passage 46 through the overflow port 461 and then flow to the bottom cover 11 through the overflow passage 46, thereby preventing the water from overflowing the dishwasher.
Optionally, a second overflow detecting device 5 is further included, and the second overflow detecting device 5 is disposed on the bottom cover 11 and is used for detecting the water level in the bottom cover 11. When the water level in the bottom cover 11 rises, the second overflow detecting means 5 gets a signal and sends it to the controller, which instructs the dishwasher to stop the water intake, and/or to draw out the water in the water cup 3, and/or to give an alarm, thus avoiding the water from overflowing from the dishwasher. The overflow detection device is provided with the first overflow detection device and the second overflow detection device 5, so that the accuracy and the reliability of overflow detection are improved. When the first overflow detecting means is out of order, the overflow condition can be continuously detected by the second overflow detecting means 5, thereby effectively preventing the water from overflowing from the dishwasher.
Alternatively, the second water overflow detecting means 5 includes a microswitch 51 and a float 52. The micro switch 51 is disposed above the bottom cover 11 and is communicatively connected with a controller of the dishwasher. A float member 52 is provided in the bottom cover 11 below the micro switch 51, the float member 52 having a density less than that of water, and when the water level in the bottom cover 11 rises, the float member 52 rises and triggers the micro switch 51. Specifically, when the microswitch 51 is triggered, the microswitch 51 sends a signal to the dishwasher controller, which instructs the dishwasher to stop the water supply and/or to draw out the water in the cup 3 and/or to send out an alarm, thereby preventing the water from overflowing from the dishwasher.
Optionally, in this embodiment, the float 52 is foam. Of course, in other embodiments, the floating member 52 may be made of a material having a density less than water, such as plastic, and is not limited thereto.
Optionally, a drain pump 6 is further included, the drain pump 6 is disposed on the base 1, the drain pump 6 is in communication with the water cup 3 of the dishwasher and in communication with the controller of the dishwasher for draining water in the water cup 3 when the probe structure is connected to the controller of the dishwasher to form a loop and/or when the float 52 rises and triggers the microswitch 51.
Optionally, an alarm assembly is included, which is in communication with the dishwasher controller, for generating an alarm when the probe structure is connected to the dishwasher controller to form a circuit, and/or when the float 52 rises and triggers the microswitch 51, to prompt the user to service the dishwasher.
