Water level in liner 5 is carried out judging to start into draining protection mechanism, solves and is only flowed into bottom plate in water in the prior art
The problem of Shi Caike is with priming level protective device, and float assembly 1 does not need bottom plate and is additionally provided support force, is not having it
Bottom plate can be saved when his demand, reduces the cost of dish-washing machine, save the inner space of dish-washing machine；Meanwhile float assembly 1 is adopted
With contactless magnetic switch 12, can be improved floating to avoid the sensitivity of greasy dirt or sundries influence float assembly 1 in water
The reliability of 1 sensed water level of sub-component.
Specifically, the water protective device in the present embodiment can be arranged in liner 5, below lower shelf, be conducive to
Rationally utilize the space in liner 5；Float assembly 1 further includes hollow fixed link 2, and fixed link 2 is fixed on the bottom of liner 5,
Floating ball 11 is the loop configuration for being embedded with magnet, and floating ball 11 is sheathed on outside fixed link 2, and magnetic switch 12 is set in fixed link 2,
Floating ball 11 can float up and down according to the water level in liner 5 in fixed link 2.Wherein, magnetic switch 12 can be tongue tube, dry spring
Pipe is also referred to as reed capsule or magnetic reed switch, is a kind of special key of magnetosensitive, is dry-reed relay and the critical piece close to switch.
Tongue tube resin-encapsulated can effectively fix tongue tube in hollow fixed link 2 in the present embodiment.When the liner of dish-washing machine
When water in 5 is in normal water level, the floating ball 11 in liner 5 will not float, and remain stationary as, at this time two panels end in tongue tube
The reed of overlapping is not magnetized, and two panels reed does not contact, and tongue tube is not triggered, dish-washing machine normal work；Work as dish-washing machine
Liner 5 in water level when reaching the peak level of setting, floating ball 11 is under the action of the buoyancy of water along fixed link 2 to moving up
Dynamic, the two panels reed in tongue tube is magnetized to different polarity by the embedded magnet of floating ball 11, and the different two panels reed of polarity will
Attract each other closure, and tongue tube is triggered at this time, sends enabling signal to control assembly, control assembly will control in dish-washing machine
Start into drain protective device.Can be water inlet by cutting off dish-washing machine or operation draining pump by liner into drain protective device
Water in 5 ejects the water level in control dish-washing machine, runs draining pump while can also be cut-out dish-washing machine water inlet, herein not
It is restricted.
The present embodiment controls opening into drain protective device by the floating ball 11 of magnetic switch 12 and embedded magnet to generate
Dynamic signal, magnet and tongue tube composition are a kind of non-contact switch, and tongue tube is set in hollow fixed link 2,
Can be to avoid with the extension of usage time, greasy dirt or sundries in water reduce the sensitivity of float assembly 1, improve float assembly
1 reliability；In addition, tongue tube is small, light-weight and relatively simple for structure, be easily installed, the space occupied it is smaller.
To prevent floating ball 11 to be detached from fixed link 2 under the action of the buoyancy of water, the upper end of fixed link 2 can be provided with limit
Structure 21, position limiting structure 21 can be and 2 integrally formed protrusion of fixed link, the raised outside projection of side wall by fixed link 2；
Can be fixed link 2 upper end edge perpendicular to fixed link 2 extending direction be inserted into gag lever post, as long as floating ball 11 can be limited
The extreme higher position floated, is not restricted herein.
Water protective device in the present embodiment further includes pedestal 3 and fixing piece 4, and pedestal 3 and fixing piece 4 are individually fixed in
The inner surface and the outer surface of the bottom of internal cavity of bowl washer 5, pedestal 3 can be integrally formed with fixed link 2, if pedestal 3 is into liner 5
Protrusion forms fixed link 2, the modes such as can also be connected through a screw thread and fix on the base 3, fixing piece 4 and pedestal 3 respectively including
The both sides of courage 5 are oppositely arranged, and can improve integrally-built intensity, stability and fixed firmness.To prevent liner 5
Interior water is flowed out by the gap of the junction of 5 bottom of pedestal 3, fixing piece 4 and liner, between pedestal 3 and liner 5 and liner
It is both provided with sealing ring 7 between 5 and fixing piece 4, prevents water from being leaked by liner 5, avoids causing other accidents.
On the basis of the above, the water protective device in the present embodiment further includes the protective cover being set in outside float assembly 1
6, accommodating space is constituted between protective cover 6 and pedestal 3, through-hole 61 is provided on protective cover 6, is flowed into and is held convenient for the water in liner 5
In emptying, so that floating ball 11 floats up and down according to SEA LEVEL VARIATION.Through-hole 61 on protective cover 6 can be arranged in protective cover 6
Bottom end keeps the water level of accommodating space identical as the water level in liner 5 always, improves the sensitive of float assembly 1 to a certain extent
Degree and accuracy.Specifically, through-hole 61 can be arranged multiple, multiple through-holes 61 may be uniformly distributed in the bottom end of protective cover 6,
The variation for accelerating water level in liner 5 and accommodating space, be further ensured that the water level of accommodating space always with the water level in liner 5
It is identical.
In addition, protective cover 6 can be detachably connected with pedestal 3, user is facilitated to float protective cover 6 and 6 inside of protective cover
Sub-component 1 is cleared up, and prevents sundries from blocking the attachment such as through-hole 61 or greasy dirt on protective cover 6 floating ball 11,2 surface of fixed link,
Cause floating ball 11 that can not be moved along fixed link 2.On this basis, protective cover 6 can be that cross-sectional area gradually increases from top to bottom
Curved-surface structure, be conducive to sundries using this curved-surface structure and flowed down along curved surface, can in order to the flow in dish-washing machine rinse protect
Shield 6, by protective cover 6 foam or sundries rinse well；Meanwhile the cross-sectional area of bottom is big compared with top, can improve guarantor
Shield 6 and 3 fixed stability of pedestal, further increase the integrally-built stabilization of water protective device.
