Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of household appliances, in particular to an anti-overflow structure of a dishwasher and the dishwasher. Background Art
[0002] In order to prevent the water in the inner tank of the dishwasher from overflowing, an overflow prevention device is set at the bottom of the dishwasher. Existing overflow prevention devices basically contain a float and a micro switch. The working principle of this type of overflow prevention device is: when the water in the inner tank of the dishwasher overflows to the bottom of the dishwasher, the float floats upward under the action of water. When the float floats up to contact with the micro switch, the micro switch will start to work and turn on the drainage pump in the dishwasher to drain the water at the bottom. As the water level at the bottom continues to drop, the float also moves downward. When it drops to separate from the micro switch, the micro switch stops working. At this time, the drainage pump also stops working, that is, the drainage stops, so that the overflow prevention function can be achieved. However, this type of overflow prevention device requires the float and the micro switch to cooperate precisely. Once there is a problem of excessive assembly error between the float and the micro switch during the assembly process, when overflow occurs, the float cannot effectively contact the micro switch, that is, the micro switch cannot work, and the drainage pump cannot be started normally to drain water. And the cost of this type of overflow prevention device is relatively high. Utility Model Content
[0003] In order to solve the above technical problems, the purpose of the utility model is to provide a dishwasher overflow prevention structure with low cost and high reliability.
[0004] The utility model adopts the following technical scheme to solve the problem: an anti-overflow structure for a dishwasher, comprising a base and a conductive probe assembly; wherein the base is provided with two mounting seats arranged opposite to each other; the conductive probe assembly comprises two conductive probes, the two conductive probes are respectively arranged in the two mounting seats, and the conductive probe assembly is used for an external power supply board or a control board.
[0005] As a further improvement of the above technical solution, the mounting seat is an insulating structure.
[0006] As a further improvement of the above technical solution, the base is also provided with a water storage tank, and the mounting seat is arranged in the water storage tank.
[0007] As a further improvement of the above technical solution, the conductive probe and the mounting seat are insulated.
[0008] As a further improvement of the above technical solution, the base is made of plastic or metal.
[0009] As a further improvement of the above technical solution, the base and the mounting seat are integrally formed.
[0010] As a further improvement of the above technical solution, the conductive probe and the mounting seat are sealed.
[0011] The beneficial effects of the utility model are as follows: the utility model provides an anti-overflow structure for a dishwasher, which comprises a base and a conductive probe assembly; wherein the base is provided with two mounting seats arranged opposite to each other; the conductive probe assembly comprises two conductive probes, the two conductive probes are respectively arranged in the mounting seats, and the conductive probe assembly is externally connected to a drainage pump controller.
[0012] When water overflows from the inner tank of the dishwasher to the base, when the water accumulated in the base submerges the conductive probe assembly, the conductive probe assembly, the accumulated water in the base, and the power board or control board externally connected to the conductive probe assembly form an energized circuit, which triggers an overflow alarm and stops all running programs of the dishwasher. If a drainage pump control program is provided in the power board or control board, the drainage pump will be operated to drain the accumulated water in the base, thereby realizing an overflow prevention function. If the power board or control board is not provided with a drainage pump control program, the power board or control board will trigger an overflow alarm and stop all running programs of the dishwasher, but will not start the drainage pump, thereby realizing an overflow prevention alarm function and effectively avoiding the problem that the dishwasher continues to work when the inner tank has overflowed.
[0013] Furthermore, the utility model is not controlled by a buoy and a micro switch, thus avoiding the problem of failure of the anti-overflow function due to imprecise coordination between the buoy and the micro switch, and the technical solution described in the utility model has a simple structure and can greatly reduce costs.
[0014] The utility model also provides a dishwasher, comprising the above-mentioned dishwasher overflow prevention structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present embodiment provides an anti-overflow structure for a dishwasher, which includes a base 100 and a conductive probe assembly; wherein the base 100 is provided with two mounting seats 200 arranged opposite to each other; the conductive probe assembly includes two conductive probes 300, which are respectively arranged in the mounting seats 200, and the conductive probe assembly is externally connected to a drainage pump controller; when water overflows from the inner tank of the dishwasher to the base 100, when the water accumulated in the base 100 immerses the conductive probe assembly, at this time, the conductive probe assembly, the accumulated water in the base 100, and the power board or control board externally connected to the conductive probe assembly form an electric circuit, at this time, an overflow alarm will be triggered, and all running programs of the dishwasher will be stopped, such as the power board or control board. A drain pump control program is provided in the control board, and the drain pump will work at this time to drain the accumulated water in the base 100, thus realizing the overflow prevention function; if the power board or the control board is not provided with the drain pump control program, then the power board or the control board will trigger the overflow alarm and stop all running programs of the dishwasher, but will not start the drain pump, thus realizing the overflow prevention alarm function and effectively avoiding the problem that the dishwasher continues to work when the inner tank has overflowed; and the utility model is not controlled by the float and the micro switch, thus avoiding the problem that the overflow prevention function fails due to the imprecise coordination between the float and the micro switch, and the simple structure of the technical solution described in the utility model can greatly reduce the cost.
[0024] In this embodiment, the mounting seat 200 is an insulating structure. The base 100 is made of plastic. In addition to plastic, the base can also be made of metal.
[0025] In this embodiment, the base 100 and the mounting seat 200 are integrally formed; the integral forming process can avoid the generation of a seam between the base 100 and the mounting seat 200, thereby improving the sealing performance of the base.
[0026] In this embodiment, the base 100 is further provided with a water tank 400, and the mounting seat 200 is arranged in the water tank 400; the conductive probe 300 is installed in the mounting seat 200, and the mounting seat 200 has a certain height. The base 100 is not provided with a water tank 400. When the accumulated water in the base 100 immerses the conductive probe 300, the accumulated water in the base 100 may be a lot. The water tank 400 is arranged on the base 100, so when water overflows from the inner tank of the dishwasher, it will flow into the water tank 400, and the mounting seat 200 is arranged in the water tank 400, so that the anti-overflow structure does not start to work until a lot of water accumulates in the base 100.
