Abstract
A water retaining structure of a household appliance switch bracket comprises the switch bracket, a door hook, a microswitch, a door hook support and a plastic base plate. The door hook support is arranged on the left or right side of the switch bracket, and the plastic base plate is arranged at the position of a door hook hole. The water retaining structure is characterized in that two water retaining pieces are symmetrically arranged on the plastic base plate, compression springs are arranged between the water retaining pieces and the plastic base plate, the compression springs drive the water retaining pieces to turn on a switch inside the plastic base plate, and therefore the sealing and water retaining effect is achieved. When the switch is turned off, the door hook is pulled out from the position between the two water retaining pieces, and the water retaining pieces are folded due to elasticity of the springs; when the switch is turned on, the door hook touches the inclined planes of the water retaining pieces, and slides into the switch bracket naturally. According to the water retaining structure, the phenomenon that water is likely to flow into an existing switch bracket is greatly avoided, the structure is simple, working is reliable, assembling is convenient and fast, the service life of an electric appliance is greatly prolonged, the using performance of the electric appliance is greatly improved, the cost is low, and the water retaining structure can be universally used.
Description
Technical field
The present invention relates to a kind of water-retaining structure of appliance switch bracket, the switch carriage of household electrical appliance is played to the effect of dash
Background technology
Nowadays, household electrical appliance kind gets more and more, and people also rely on more to household electrical appliances.During household electrical appliances work, unnecessary water, wet goods impurity flow into switch carriage; Or the door stop hole of plastic base plate still opens wide when door is opened, if now water or other impurity flow into, cause live part short circuit or play baked wheaten cake chance and bring the damage that cannot make up to electrical equipment, even danger is caused to user.Therefore, process appliance switch being carried out to dash or waterproof is needed.On May 21st, 2014, Chinese patent literature CN203607290U discloses a kind of button switch waterproof structure, and comprise button, elastomer and strutting piece composition, wherein, button is arranged on casing, and user realizes the function of electronic installation by pressing keys; Elastomer covers on casing, is located in the middle of casing and button, during gear pressing keys, and the direct contact resilient body of button, the active force pressed by elastomer transmission thus be pressed into push switch further; Strutting piece is installed on elastomer, fixes this elastomer, and when making to press this button, this elastomeric shape can not change.It is said, this invention is worked in coordination by casing and supporting member, and elastomer is stable in the middle of the two, and the position that elastomer and shell are directly contacted reaches the object of waterproof due to elastomeric crimp.But, because elastomer reaches waterproof object by crimp, make water resistance stable not, be further improved.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of water-retaining structure of appliance switch bracket, and it can prevent appliance switch bracket from intaking.
In order to solve the problems of the technologies described above, the invention provides a kind of water-retaining structure of appliance switch bracket, it comprises switch carriage, door stop hole, is arranged at the gate stop bearing of switch carriage left/right side and is arranged at the plastic base plate at door stop hole place, it is characterized in that described plastic base plate being symmetrically arranged with two block water plates; And be provided with Compress Spring between described block water plate and plastic base plate, realize open and close movement by Spring driving block water plate at plastic base plate, reach the effect of sealing dash.Plastic base plate arranges block water plate, and arrange spring between block water plate and plastic base plate, when switch is in opening, gate stop is extracted out between two block water plates, and block water plate closes up due to the elastic force of spring; When position switch is in closure state, the inclined plane of gate stop touching block water plate, takes advantage of a situation and slips in switch carriage, and produce interlock and electrical equipment is normally worked, in this process, block water plate separates to both sides, under the effect of Compress Spring, tightly touch gate stop, reduces door stop hole gap.
The groove corresponding with bottom block water plate is provided with inside described plastic base plate; And described plastic base plate both sides are also provided with the fixing limiting section of triangle; Described plastic base plate and switch carriage are fastened and connected.By arranging the groove corresponding with bottom block water plate in plastic base plate inside, block water plate can be made therein to slide; The fixing limiting section of the triangle of plastic base plate both sides, can make plastic base plate be fixedly connected with switch carriage.
One end of the corresponding Compress Spring of described plastic base plate, is provided with corresponding recess; Described Compress Spring one end is arranged in recess.Plastic base plate is provided with the recess of corresponding Compress Spring, makes Compress Spring easy for installation, stable and not easily eject after installing.
Described block water plate arranged outside has the lead of protrusion; Inclined plane is set to inside described block water plate; And the another both sides of described block water plate are also provided with the fixed part of triangle; Described block water plate is that plastics POM makes.Block water plate afterbody is provided with a protrusion cylinder and can leads Compress Spring, and block water plate both sides have triangle reverse to buckle in plastic base plate chute, and working stability is reliable, and plastics POM has high strength, high abrasion and the low feature of coefficient of friction.
Described Compress Spring is column type; Described Compress Spring radius is 2.4mm; Described lead is connected with the Compress Spring other end.
The fixing limiting section of the corresponding plastic base plate both sides of described switch carriage, is provided with corresponding cooperation fixed part.
The block water plate that the present invention substantially improves in existing switch carriage easily flows into water problem, and its structure is simple, reliable operation, assembling are convenient, not only substantially increase serviceability and the life-span of electrical equipment, and cost is low, can be widely used.
