Abstract
The utility model relates to a washing machine magnetic safety switch assembly, comprising a surface plane, a cover plate, a permanent magnet and a magnetron. The permanent magnet and the cover plate are formed by integrated injection moulding; the magnetron is installed on the surface plane; the permanent magnet and the magnetron approach when the cover plate is closed. When a washing machine cover plate is closed, the permanent magnet and the magnetron approach, two metal elastic reeds installed in the magnetron mutually contact under magnetic action to form a closed circuit and a washing tube starts working; when the washing machine cover plate is open, the permanent magnet and magnetron are far from each other, the metal elastic reeds are separated to form an open circuit and the washing tube stops working. The structure is simple and use is convenient. The permanent magnet and the cover plate are formed by integrated injection moulding, which can avoid the possibility of abnormal sound caused by magnet shaking owing to existence of assembling gap, meanwhile omits assemblies for fixing magnets, reduces costs and increases security coefficient.
Description
Technical field
The utility model relates to safe on-off of washing machine, relates in particular to a kind of magnetic safety switch of washing machine assembly.
Background technology
In recent years, market is universal at home gradually comes for washing machine, becomes indispensable household electrical appliance in people's life.Safe on-off of washing machine is under a kind of assurance washing of drum type washing machine barrel operation status, the safety switching apparatus that washing tube is stopped operating rapidly.The displacement play may occur due to what on the cover board permanent magnet position was installed, cause permanent magnet that the magnetic of magnetron is weakened, the situation that when cover plate occurring and opening, washing tube is still worked easily damages, and has potential safety hazard.
Summary of the invention
For solving problems of the prior art, the purpose of this utility model is to provide a kind of simple in structure, safe and reliable magnetic safety switch of washing machine assembly.
Embodiment of the present utility model: a kind of magnetic safety switch of washing machine assembly, comprise face frame, cover plate, permanent magnet and magnetron, it is characterized in that: described permanent magnet and cover plate are integrated injection mo(u)lding, described magnetron is arranged on the face frame, and described permanent magnet and magnetron position when the face frame is closed is approaching.
Described magnetron comprises outer tube and two interior metallic elastic reeds of outer tube is installed, metal spring leaf tail end connection power lead.
The beneficial effects of the utility model:During the washing machine cover plate closing, permanent magnet and magnetron position approach, and two metallic elastic reeds installing in magnetron contact with each other under magnetic action, form closed circuit, and washing tube is started working; When cover plate for washing machine is opened, permanent magnet and magnetron away from, the metallic elastic reed separates, and forms open circuit, washing tube quits work, it is simple in structure, easy to use.Permanent magnet and cover plate are integrated injection mo(u)lding, have avoided owing to there being the fit-up gap, magnet are rocked cause the possibility of abnormal sound, have also saved the accessory of fixed magnet simultaneously, have reduced cost, have increased coefficient of safety.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is magnetron structures schematic diagram of the present utility model.
In figure: 1, face frame, 2, magnetron, 3, permanent magnet, 4, cover plate, 5, outer tube, 6, the elastic metallic reed.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of magnetic safety switch of washing machine comprises face frame 1, cover plate 4, permanent magnet 3 and magnetron 2, and permanent magnet 3 is integrated injection mo(u)lding with cover plate 4, and magnetron 2 is arranged on face frame 1; Magnetron 2 comprises outer tube 5 and two interior elastic metallic reeds 6 of outer tube 5 is installed, metal spring leaf 6 tail ends connection power leads.When cover plate for washing machine 4 was closed, permanent magnet 3 and magnetron 2 positions were approaching, are on same axis, and the metallic elastic reeds 6 of installing in magnetron 2 contact with each other under magnetic action, form closed circuit, and washing tube is started working; When cover plate for washing machine 4 is opened, permanent magnet 3 and magnetron 2 away from, metallic elastic reed 6 separates, and forms open circuit, washing tube quits work, it is simple in structure, easy to use.Permanent magnet 3 is integrated injection mo(u)lding with cover plate 4, has avoided making permanent magnet 3 rock the possibility that causes abnormal sound owing to there being the fit-up gap, has also saved the accessory of fixing permanent magnet 3 simultaneously, has reduced cost, has increased coefficient of safety.
Claims (2)
