The purposes of toaster be by heat radiation bread baking to sallow state, outer soft in crisp, strengthen mouthfeel.The lifting structure of tradition toaster be by push away the bar seat, push away bar, parts such as handle support, handle, guide pillar, spring, magnet assemblies, switch module form, by manual operation, overcome various spring forces, the handle that exposes is applied a downward pressure, when being depressed into extreme lower position, the closed energising of switch module, magnet assemblies produces magnetic field, hold flat thin magnet, make to push away bar and remain on extreme lower position, the heater baking bread of starting working.When having arrived setting-up time, magnet assemblies loses magnetic field, and switch module is cut off the electricity supply, and pushes away bar under the effect of spring force bread is lifted to desired location.This structure has following shortcoming: 1. it is bigger to overcome the downward pressure that handle is implemented; 2. suction is not enough, in normal bake process, is subjected to the extraneous vibration influence, and magnet assemblies fails to hold flat thin magnet, will produce undesired outage midway, and bread is upspring.3. elastic force is excessive, in holding up the process of bread, and might be the bread bullet furnace chamber that flies out; Or elastic force is too small, the set height position of upspringing of failing.
Along with people's living standard improves constantly, begin to occur having the toaster of automatic lifting bread function on the market.Chinese patent literature CN2726313 discloses a kind of toaster bread carriage automatic hoisting mechanism on September 21st, 2005, comprise: can be installed in the slide-bar on the right riser in the toaster, be nested with the crane on slide-bar, the bread support of fixedlying connected with crane, it is characterized in that: a side of crane is provided with a guide groove that is used to cooperate reversed column, and described reversed column is installed on the output gear side panel face of a transmission mechanism that is made of motor and driving gear set.Start crane by this transmission mechanism, realize the automation of action up or down of toaster bread carriage.It is said that it has simple and reasonable for structure, have plurality of advantages such as easy for operation, bread carriage stable action, power consumption be low, safe and reliable.But, this structure adopts gear train to drive crane, because the cost of manufacture of gear is higher, and gear often needs with lubricator to be lubricated, lubricant infiltrates in the bread easily, and if there is bread to go to sticks and staves into gear, then can influence the operate as normal of gear, people also comparatively bother when cleaning, require further improvement.
The utility model content
The purpose of this utility model aims to provide the automatic hoisting mechanism that a kind of simplicity of design toaster bread reasonable, durable in use, easy to clean pushes away bar, to overcome weak point of the prior art.
Push away the automatic hoisting mechanism of bar by a kind of toaster bread of this purpose design, comprising slides to be provided with on the guide shaft that vertically is arranged on the toaster inboard, the guide shaft pushes away the bar seat, bread pushes away bar one side and is fixed on and pushes away on the bar seat, motor is fixed on the motor cabinet, and motor cabinet is passed in the rotating shaft of motor, upper limit switch and limit switch are positioned at a side of guide shaft, and its architectural feature is that the rotating shaft of motor pushes away the bar seat by the rocker arm body connection.
Described rocker arm body comprises the rocking arm that is arranged on loose slot that pushes away on the bar seat and the rotating shaft that is connected loose slot and motor.
Be provided with axle sleeve in the described loose slot, axle sleeve is connected with an end of rocking arm by the hinge chain rivet; The terminal rectangular or cross of the rotating shaft of motor, the shape of the corresponding rotating shaft end of an other end of rocking arm is provided with connector and is attached thereto.
Described rocking arm is the lever of single-unit or the crank rocker that is formed by hinge by two joint levers.
Described loose slot is in-line or circular arc.
Described upper limit switch and limit switch are fixed on the switch bracket, push away that the position of corresponding upper limit switch and limit switch is provided with feeler lever on the bar seat.
Described motor cavity is above or below the guide shaft.
Described motor is synchronous motor at a slow speed.
The utility model pushes away at bread the device that makes its automatic lifting is set on the bar, after machine operation, can control bread automatically and drop to desired location, the heater of toaster is started working then, bread rises to original height automatically during to the scheduled time, and the control heater quits work, and can also control the lifting of bread in bake process.It pushes away the bar structure with the spring of traditional toaster and compares, and has advantages such as simple in structure, easy to operate, that automation is high, cost of manufacture is low.
