Balladeur train 1 pressurized moves down process:
When the user toasts bread with toaster, the user presses the handgrip 101 on the balladeur train, when balladeur train 1 pressurized moves down, owing to have a bit of between nut 2032 and the compressing tablet 2031 for the distance of piston rod 203 with respect to slip between the support chip 102, support chip 102 will be pressed on the compressing tablet 2031 to lower slider with respect to piston rod 203, promote piston rod 203 and piston 204 and move down.Here be provided with between nut 2032 and the compressing tablet 2031 and eliminate part error when this segment distance is mainly used in assembling, be convenient to assembling, this segment distance can not be provided with yet, and can have enough surpluses to solve for the displacement of piston 204 by increasing the length of piston cylinder 205.When piston 204 is mobile on the locational pore 2051 of A, because the diameter of through hole 2071 is bigger than the diameter of piston rod 203, be provided with certain clearance between the through hole 2071 of piston rod 203 and the loam cake 207 that passes, add the pore 2051 that piston cylinder 205 is provided with on the A position, make the air pressure in the piston cylinder 205 keep the same with outside air pressure, and the piston ring 2042 that contacts with piston cylinder 205 on the piston 204 is to adopt the rubber-like flexible material, it is very little with frictional force between the piston cylinder 205 and cooperate closely, before balladeur train 1 moves down into pore A position, the downforce of balladeur train 1 is almost constant, only need overcome the elastic force of spring 4.Continue to move down and work as balladeur train 1, after making the pore 2051 of piston 204 by position A on the piston cylinder 205, because of piston 204 is provided with hole 2041, when when the air pressure of piston 204 between piston cylinder 205 bottoms moves down because of piston 204, being connected with the air pressure of piston rod 203 one side (being provided with diaphragm seal 2043) greater than piston 204, diaphragm seal 2043 on the piston 204 (the general employing than soft materials such as rubber made) is backed down by air pressure, air outwards flows out by hole 2041, make piston 204 keep basic identical with the air pressure of piston cylinder 205 outsides to the air pressure between piston cylinder 205 bottoms, for this reason, in the process that balladeur train 1 moves down, though in the middle of balladeur train 1 and frame 11, be provided with balladeur train damping unit 2, can not increase the pressure that balladeur train 1 moves down substantially.When moving down into, balladeur train 1 covers the free end that drive unit 131 and 131-1 top bending hook portion are pushed down the lid support 121 and the 121-1 other end, and when continuing to move down, top cover 12 and 12-1 begin closed under the driving of lid support 121 and 121-1, when below the lacing film on the balladeur train 1 104 moves down into armature hook 301, top cover 12 and 12-1 closure, the depression bar that is provided with on the balladeur train 1 is with power switch (not drawing here) closure, toaster begins to toast bread, simultaneously, armature coil 3 must electricly hold armature and hook 301, lacing film 104 on the balladeur train 1 is tangled by armature and hook 301, makes balladeur train 1 remain on the toaster bottom.At this moment, described piston 204 has moved down into the bottom position of piston cylinder 205.
Balladeur train 1 process of moving up that resets:
When the stoving time of user's setting is finished in the toaster baking, armature coil 3 dead electricity that control circuit control toaster bottom is provided with, armature on it and hook 301 are released because of losing suction, balladeur train 1 upwards rises under the effect of spring 4 elastic force, and the lacing film 104 that is provided with on the balladeur train 1 breaks away from hook 301.At this moment, piston rod 203 is subjected to the pulling force that balladeur train 1 upper support sheet 102 makes progress and piston 204 is moved up.Since the pore that on the A position of piston cylinder 205, is provided with below 2051 by piston 204 sealed space, the distance that piston 204 moves up along with piston 204 to the air pressure between piston cylinder 205 bottoms increases and diminishes, because the air pressure that piston cylinder 205 is outward a piston 204 to be connected with piston rod 203 is greater than the air pressure of piston 204 towards piston cylinder 205 bottoms one side, diaphragm seal 2043 is adjacent on piston 204 by gas pressure, hole on the piston 204 2041 is sealed, like this, because the air pressure in the piston cylinder 205 is less than the air pressure outside the piston cylinder 205, therefore, the mobile of piston 204 blocked, the speed that balladeur train 1 rises is also blocked, and has slowed down the speed that balladeur train 1 rises.At this moment, the segment distance because balladeur train 1 has moved up, at this moment, lid drive unit 1031 and 1031-1 top bending hook portion have been left the free end of the lid support 121 and the 121-1 other end, and top cover 12 and 12-1 open under the effect of extension spring 122 and 122-1.In piston cylinder 205, upwards move through the A position of pore 2051 when piston 204 after, extraneous air enters in the piston cylinder 205 by pore 2051, make the air pressure in the piston cylinder 205 consistent with external pressure, at this moment, piston 204 moves up and does not have the little problem of piston cylinder 205 internal gas pressures, and balladeur train 1 rises to the normal position with uncrossed speed.Like this, after on balladeur train 1 and the frame 11 balladeur train damping unit 2 being set, toaster with cover is owing to blocked in the starting stage that balladeur train 1 rises, slowed down the rate of climb of balladeur train 1, make top cover obtain the time of fully opening, the lid drive unit 1031 that is provided with on the balladeur train 1 and 1031-1 rise with balladeur train 1 a bit of after, top cover is opened, the rise of balladeur train 1 can not make bread withstand on the top cover, so promptly simplified the structural design of toaster with cover, two balladeur train structural changes are become single balladeur train structure, promptly adopt a balladeur train just can finish the driving of toaster cover and dragging of bread, for example the applicant is that two balladeur train structures in ' toaster ' domestic patent of invention of 200810217156.x can be reduced to above-mentioned single balladeur train structure in the patent No. of on October 31st, 2008 application.Also simplified circuit design simultaneously, save the cost of product, the popularization of toaster with cover with energy-saving effect has been had big meaning, in addition, also solved the little bread of roasting weight and do not flown problem, guaranteed also that the big bread of weight can normally rise to put in place by bullet.
The piston type damping unit of balladeur train damping unit 2 of the present invention, can also be designed to another kind of structure, as shown in Figure 3, with 2041 cancellations of the hole on the piston 204 in the balladeur train damping unit 2 among Fig. 1,2, and open a hole 2053 at sealing one end of piston cylinder 205.With diaphragm seal 2043 cancellations that were arranged on originally on the piston 204; and identical diaphragm seal 2052 is arranged on outside sealing one end of piston cylinder 205; have the lower cover 209 in hole in the middle of also being provided with; with the sealing one end socket of piston cylinder 205, be used for protecting diaphragm seal 2052 not fragile in the production assembling.
Its operation principle is as follows: the user presses the handgrip 101 on the balladeur train, when balladeur train 1 pressurized moves down, piston 204 is moved down, before passing through pore 2051, because the diameter of through hole 2071 is bigger than the diameter of piston rod 203, be provided with certain clearance between the through hole 2071 of piston rod 203 and the loam cake 207 that passes, add the pore 2051 that piston cylinder 205 is provided with on the A position, make the air pressure in the piston cylinder 205 keep the same with outside air pressure, and the piston ring 2042 that contacts with piston cylinder 205 on the piston 204 is to adopt the rubber-like flexible material, frictional force between itself and the piston cylinder 205 is very little, move down at balladeur train 1 before the position of pore 2051, the downforce of balladeur train 1 is almost constant, only need overcome the elastic force of spring 4.Continue to move down and work as balladeur train 1, after making the pore 2051 of piston 204 by position A on the piston cylinder 205, because of sealing one end of piston cylinder 205 is opened a hole 2053, diaphragm seal 2052 is arranged on the sealing one end outside of piston cylinder 205, when the air pressure of piston 204 between piston cylinder 205 bottoms moves down because of piston 204 greater than piston cylinder 205 outside the one side (being provided with the one side of diaphragm seal 2052) air pressure the time, diaphragm seal 2052 is backed down by air pressure, air outwards flows out by hole 2053, make piston 204 keep basic identical with the air pressure of piston cylinder 205 outsides to the air pressure between piston cylinder 205 bottoms, for this reason, in the process that balladeur train 1 moves down, though in the middle of balladeur train 1 and frame 11, be provided with balladeur train damping unit 2, can not increase the pressure that balladeur train 1 moves down substantially.
When toaster baking bread reaches the stoving time of user's setting, control circuit makes armature coil 3 dead electricity, hook 301 is released, balladeur train 1 rises under the effect of spring 4, the lacing film 104 that is provided with on the balladeur train 1 breaks away from hook 301, the operation principle of the balladeur train damping unit 2 of the operation principle of balladeur train damping unit 2 and above-mentioned Fig. 1 was basic identical when balladeur train 1 rose, and just diaphragm seal 2052 is provided with different with 2053 positions, hole.
Finish the driving of lid and dragging of bread baking in order to realize toaster with cover with single balladeur train, and a toaster can toast the bread of Different Weight, in the time of mainly must realizing that the toaster bread baking finishes, the starting stage speed that balladeur train rises can not be too fast and cause bread to withstand top cover, or the bread bullet that weight is little flies, in order to address this problem, the present invention also has following scheme to realize.
Be the embodiment (two) of the damping unit of toast stove carriage of the present invention as shown in Figure 4, the frame 11 of present embodiment is provided with vertical shaft 5, one end of vertical shaft 5 is connected with the top of frame 11, and the other end passes balladeur train 1 and is connected with the bottom of frame 11 with the spring 4 that is in balladeur train 1 below.Balladeur train 1 and spring 4 form with vertical shaft 5 and are slidingly connected, and are provided with the balladeur train damping unit between frame 11 and the balladeur train 1, and described balladeur train damping unit is made up of by the friction plate assembly 6 of friction member roll wheel assembly 7 and conduct as friction member.Wherein, roll wheel assembly 7 is made of gear 701, gear stand 702 and back-moving spring 703, the hinged gear 701 of one end of gear stand 702, the other end is hinged on the balladeur train 1, an end that connects back-moving spring 703 at the middle part of gear stand 702, the other end of back-moving spring 703 is connected with balladeur train 1, and the below of gear stand 702 also is provided with limited post 105; Friction plate assembly 6 is provided with tooth bar 601, and the lower end of friction plate assembly 6 is fixed on the bottom of frame 11, tooth bar 601 and gear 701 corresponding settings.Be connected with on the balladeur train 11 and cover drive unit 1031 and 1031-1, the bending hook portion of lid drive unit 1031 and 1031-1 is in the top of top cover support 121 and 121-1 other end free end, and corresponding with it.
The operation principle of the damping unit of described toast stove carriage:
Balladeur train 1 folding process: when balladeur train 1 was displaced downwardly near the bottom, because gear 701 contacts with tooth bar 601, during the power that is subjected to upwards lifting, gear stand 702 upwards lifted, and gear 701 slips on tooth bar 601 surfaces, and the downforce that moves down increases hardly.When gear 701 arrived the bottom of toaster by tooth bar 601, balladeur train 1 was remained on the bottom by armature coil 3 and armature hook 301, and the effect that gear stand 702 is subjected to back-moving spring 703 pulling force resets.
