This embodiment discloses a dishwasher, as shown in fig. 1, 2 and 5, comprising a base 1, an overflow detecting device 2 and a soleplate 3 detachably connected, the soleplate 3 being lower than the base 1. The overflow detecting device 2 includes a fixed seat 21, a micro switch 22 and a float 23, both the micro switch 22 and the float 23 are disposed in the fixed seat 21, and the float 23 is located below the micro switch 22. A connecting piece is arranged on the side face of the fixing seat 21, a mounting through hole 11 is arranged on the base 1, the connecting piece is connected to the mounting through hole 11, and the bottom face of the overflow detecting device after mounting is lower than the mounting through hole 11. The distance between the bottom surface of the float 23 and the bottom plate 3 is smaller than a set value, and the float 23 can contact the water surface during overflow. Other structures of the dish washer are the same as those of the prior art, and are not described herein.

The float 23 is preferably made of a low-density material such as foam, and when the water level on the bottom plate 3 reaches a certain height, water can push the float 23 to float upwards. When the float 23 floats up to a set height, the protrusion 231 on the top of the float 23 can abut against the contact 221 of the micro switch 22, thereby triggering the micro switch 22.

The connection member is provided on the side of the fixing base 21 and is higher than the float 23, i.e., the bottom surface of the connection member is higher than the bottom surface of the float 23, so that the fixing base 21 can be connected to the base 1, and the float 23 is substantially attached to the bottom plate 3. When the overflow detection device 2 is disassembled, the base 1 and the bottom plate 3 can be disassembled firstly, then the fixing seat 21 is disassembled from the base 1, the disassembly and the assembly are more convenient, the limit of the installation position is less, and the design difficulty is low. The maintenance efficiency of the overflow detection device 2 is high, the fixed seat 21 can be repeatedly assembled and disassembled with the base 1, and the service life is long; the float 23 is sensitive to the water surface lifting reaction, the micro switch 22 is sensitive to trigger, and the dishwasher can accurately and timely send overflow alarms.

On the basis of the above structure, the bottom plate 3 is inclined, and the float 23 is located at the lowest point of the bottom plate 3. Preferably, the bottom plate 3 is provided with a water storage recess (not shown) in which the float 23 is located. When the inner container of the dish washer leaks, water flow is converged into the water storage groove. As the water flow builds up, the liquid level rises continuously. When the water level in the water storage groove rises to a certain height, the floater 23 is pushed by the buoyancy of the water level to rise, the bulge 231 is abutted against the contact 221 so as to trigger the micro switch 22, the micro switch 22 sends a signal to a control device (not shown), and the control device starts a flash lamp, a buzzer and other alarm devices to send an overflow alarm to a user.

As shown in fig. 3 and 4, the fixed seat 21 includes a cylindrical seat body 215, and the float 23 is penetrated in the seat body 215. The bottom of the seat main body 215 is provided with a limit support 216, the float 23 is provided with a limit groove 233, and the limit support 216 can be embedded in the limit groove 233. The stopper 216 can hold the float 23 from the bottom, thereby restricting the float 23 within the seat body 215, and the float 23 is not detached from the seat body 215 during the process of attaching and detaching the overflow detecting device 2.

A plurality of arc-shaped water passing holes 218 are provided at the bottom side of the seat body 215, and water flows from the water passing holes 218 into the interior of the seat body 215 for pushing the float 23 upward. In this embodiment, the connector is higher than the top end of the water passing hole 218, so that water does not spread on the base 1.

In order to make the moving track of the float 23 more controlled in the floating process, the fixing seat 21 is provided with a positioning column 217, the float 23 is provided with a guide hole 232, and the positioning column 217 is penetrated in the guide hole 232. During the upward movement of the float 23, the positioning column 217 can guide the float 23, so that the float 23 is prevented from skewing or rotating around the axis, and the response to the water level lifting is more sensitive and accurate.

Furthermore, the float 23 can be designed to be stepped, the fixing seat 21 is correspondingly stepped, and the side surface of the stepped structure can also play a limiting and guiding role.

On the basis of the above structure, the specific structure of the connecting piece is not limited, and the fixing base 21 can be conveniently connected to the base 1. As shown in fig. 3 to 5, the first connector structure includes a mounting surface 211 formed along a radial extension of the fixing base 21, and an undercut 212 and a limiting portion 214 are provided on a bottom surface of the mounting surface 211. The back-off 212 can be arranged in the mounting through hole 11 in a penetrating way, so that the fixing seat 21 is clamped on the base 1. The position department of seting up installation through-hole 11 on the base 1 is a dull and stereotyped structure, and back-off 212 penetrates installation through-hole 11 after, and back-off 212 butt is on the bottom surface of this dull and stereotyped structure, and the bottom butt of spacing portion 214 is on the top surface of this dull and stereotyped structure, and spacing portion 214 and back-off 212 are from two upper and lower directions respectively supporting dull and stereotyped structure, realize fixing base 21 and the stable connection of base 1.

In order to avoid the fixing seat 21 from shaking relative to the base 1, the distance between the limiting portion 214 and the back-off 212 is smaller than or equal to the wall thickness of the mounting through hole 11 (i.e. the thickness of the flat plate structure), and after the back-off 212 penetrates into the mounting through hole 11, the periphery of the mounting through hole 11 can be tightly clamped by the limiting portion 214 and the back-off 212.

After the overflow detecting device 2 is installed, the back-off 212 can prevent the installation surface 211 from moving upwards, the limiting part 214 can prevent the installation surface 211 from moving downwards, so that the installation surface 211 is fixed relative to the base 1, the float 23 is basically attached to the bottom plate 3, and once the overflow condition occurs, the float 23 can contact the water surface as soon as possible.

In order to accommodate the height difference between the base 1 and the bottom plate 3, the connector further includes a limiting member 213, and the limiting member 213 is connected between the side surface of the fixing base 21 and the mounting surface 211. Meanwhile, the limiting piece 213 is abutted on the side surface of the base 1, so that the fixing seat 21 is prevented from laterally shaking relative to the base 1. The limiting piece 213 and the mounting surface 211 form a ladder structure, the mounting surface 211 is lifted, a larger mounting space is reserved for the back-off 212, and the dismounting difficulty of the overflow detection device is further reduced.

The second connector structure comprises a slider (not shown) with corresponding sliding grooves on the base 1. During installation, the slide fastener enters the slide groove from the gap of the side surface of the slide groove, so that the connection between the fixing seat 21 and the base 1 can be completed, and the disassembly efficiency is high.
