Abstract
The utility model relates to an uncovering safety detection device for a pulsator washing machine, which comprises a face frame and a door cover. A permanent magnet is arranged on the door cover, a reed pipe matched with the permanent magnet is arranged on the face frame, and the reed pipe is connected with a controller. When the door cover is closed, the distance A between nearest end faces of the permanent magnet and the reed pipe is smaller the 10 mm. By means of the technical scheme, the reed pipe and the permanent magnet which are matched are positioned on the face frame and the door cover respectively, the reed pipe can be disconnected and connected under the action of the magnetism effective distance of the permanent magnet, and the controller can detect the change and send signals to a motor to lead the motor to work or stop.
Description
Technical field
The utility model relates to a kind of checkout gear, relates to a kind of safety detection device of uncapping that is used for rotary drum washing machine specifically.
Background technology
Rotary drum washing machine is when high speed dewatering, and clothing can not have regular distribution at dehydration bucket circumference along with the rotation of dehydration bucket one superhigh speed yet; If this moment, hand put in the bucket, twined by clothing, will cause great injury to health; So general dehydration bucket top is provided with door closure, and will accomplish that when door closure is opened the dehydration bucket is in the very short time; Dewatering speed can lower, and prevents human body is damaged, and this is commonly referred to the safety detection of uncapping of washing machine.At present, the safety detection of uncapping of washing machine is that two copper reeds are installed at the cover plate rear portion, in the cover plate open and close; Two reeds are broken off and closure through structure; This is this control mode complex structural designs, and the angular dimension of uncapping is influenced by door closure, face frame and the tolerance stack of reed own, and is wayward; Reliable in action property reduces with long-time use, and this copper reed is prone to produce distortion in producing, transport and assembling simultaneously.
Summary of the invention
The purpose of the utility model provides a kind of rotary drum washing machine safety detection device of uncapping, and this installs simplicity of design, and security performance is good.
For realizing above-mentioned purpose; The utility model has adopted following technical scheme: comprise face frame and door closure; Door closure is provided with permanent magnet, and the face frame is provided with the tongue tube that matches with permanent magnet, and tongue tube links to each other with controller; When door closure was closed, the distance A between the nearest end face of permanent magnet and tongue tube was less than 10mm.
Tongue tube of the utility model and the adhesive of permanent magnet distance are greater than 12mm, and the break distance of tongue tube and permanent magnet is greater than 15.5mm.
The tongue tube of the utility model is the open type tongue tube.
Permanent magnet of the utility model and door closure directly are injection molded into one.
Can know by technique scheme; The utility model is through being provided with tongue tube and the permanent magnet that cooperatively interacts respectively on face frame and door closure; Tongue tube can break off under the effect of the magnetic coverage of permanent magnet and be closed; Detect this variation through controller simultaneously, and transmit signal and make machine operation to motor or quit work.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the control flow chart of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified:
A kind of rotary drum washing machine as shown in Figure 1 safety detection device of uncapping; Comprise face frame 10 and door closure 20, door closure 20 is provided with permanent magnet 21, and face frame 10 is provided with the tongue tube 11 that matches with permanent magnet 21; Tongue tube 11 links to each other with the input of controller; The output of controller links to each other with motor, and during door closure 20 closures, the distance A between permanent magnet 21 and tongue tube 11 both nearest end faces is less than 10mm.
As the preferred version of the utility model, the adhesive of tongue tube 11 and permanent magnet 21 distance is greater than 12mm, and the break distance of tongue tube 11 and permanent magnet 21 is greater than 15.5mm, and tongue tube 11 is the open type tongue tube.Being exactly that tongue tube 11 is as many as specifically is one door closure 20 is in closed condition when the washing machine operate as normal near switch that at this moment tongue tube 11 is closed under the magnetic action of permanent magnet 21; If door closure 20 is opened, the distance between tongue tube 11 and the permanent magnet 21 is during greater than the 15.5mm millimeter, and tongue tube 11 breaks off, and controller obtains signal, stops to the motor power supply, and motor can guarantee user's safety in the second of setting stall in the number.
As more preferred scheme, permanent magnet 21 directly is injection molded into one with door closure 20, and production is got up simple and convenient, has overcome traditional copper reed yielding problem in producing, transport and assembling.
The concrete operations step is following:
1) dehydration beginning; 2) open drain motor; 3) draining finishes and then opens dehydration electric motor, and draining does not finish, and then returns and opens drain motor, finishes until draining; 4) open dehydration electric motor, setting dewatering time is five minutes; 5) open door closure after satisfying five-minute period, tongue tube breaks off, and gets into and closes draining, dehydration electric motor program, opens door closure during less than five minutes, and tongue tube breaks off, and controller provides signal to make the motor outage, returns the step of opening dehydration electric motor again; 6) closing behind draining, the dehydration electric motor alarm signal rings.
Above-described embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that those of ordinary skills make the technical scheme of the utility model all should fall in the definite protection domain of the utility model claims.
