Description
Technical field
The utility model relates to foodstuff heating box, particularly a kind of locking pressure oven.
Background technology
Pressure oven is a kind of conventional food heating device, human consumption after food is heated in casing.Owing to containing moisture in food, therefore moisture can be made to evaporate the heating of food in baking box, cause the pressure in baking box to exceed external pressure; Existing baking box in order to safety can by the earth pressure release in baking box, some baking box, in order to accelerate the slaking speed of food, needs keep the pressure in baking box and become pressure oven; Pressure oven needs to keep casing to be connected with locking firm between chamber door, latch-up structure between the chamber door of pressure oven conventional at present and casing is fairly simple, as: chamber door is arranged metal derby or magnet that on magnet, casing, setting matches with magnet, by both adhesives, realize the locking of chamber door and casing; The shortcoming of this latch-up structure is:, due to the food moisture content heated in baking box there is gap and gap be difficult to expect, the steam produced after the heat foods that water content is large can cause the pressure in baking box to exceed the locking between chamber door and casing, chamber door non-controlling is caused to be opened, steam in casing is put out, and damages neighbouring people; People touch chamber door in operation and also may cause that chamber door is improper to be opened in addition, damage, have the space of improvement to people.
Utility model content
The utility model is to overcome defect in above-mentioned prior art, provides a kind of locking pressure oven that can prevent chamber door from surprisingly performing fighting.
For achieving the above object, the utility model provides a kind of locking pressure oven, comprising: casing, chamber door, the second locking piece being arranged on the first locking piece on chamber door and being connected with casing;
Described first locking piece and chamber door are fastenedly connected, and comprise a latch hook;
The control lever that described second locking piece comprises lockplate and is connected with lockplate, described lockplate moves under the driving of control lever, and lockplate is also provided with snap close, and the lockplate driving snap close of movement matches to link or depart from described latch hook and links;
Described control lever is connected with body pivot by rotating shaft, position between the leading section of control lever and rotating shaft is provided with and locks spring first tie point, casing is provided with locking spring second tie point, locking spring is connected between two described spring connecting point, when control lever rotates around the axis and drives described latch hook and snap close to link, locking spring is stretched, simultaneously, spacing is produced between locking spring and rotating shaft, the pulling force of locking spring drives control lever maintenance torque lock around the shaft, thus remain lock-out state between driving latch hook and snap close, when control lever rotates backward around the shaft, latch hook and snap close depart from and link, simultaneously, locking spring keeps conllinear or crosses rotating shaft forming a unlatching torque reverse with torque lock with rotating shaft after overcoming torque lock.
By above-mentioned setting, rotated around the axis by control lever, the second locking piece and the first locking piece is driven to link and disengaging, the driving force that torque lock between locking spring and rotating shaft drives control lever to remain to lock chamber door stablizing when ensureing that chamber door is opened, make locking pressure oven more reliable and secure, avoid chamber door and surprisingly open human body is damaged; The unlatching torque of locking spring can make the opening of chamber door stablize.
Be set to further: described control lever is also provided with back-moving spring first tie point, casing is provided with back-moving spring second tie point, back-moving spring is connected between two back-moving spring tie points, control lever is rotated in the process forming torque lock, back-moving spring tie point produces and shifts and drive between back-moving spring and rotating shaft and form reset torque, and the direction of reset torque is contrary with the direction of torque lock and be less than torque lock.
By above-mentioned setting, reset torque is less than torque lock and makes the lock-out state of control lever can not be subject to the impact of reset torque, and control lever, when removing latch hook and snap close links, carrys out complete operation by applying less power after reset torque; Back-moving spring is also beneficial to when chamber door is opened and keeps control lever to be in stable position.
Be set to further: the top of described casing is provided with relief valve, between described control lever and relief valve, linkage unit is set, the linkage unit that moves through of described control lever drives relief valve to open or closes: pull control lever when latch hook and snap close being unlocked, control lever drives relief valve to open, pressure in casing is released, when opening chamber door, the pressure in casing reduces; When described chamber door is closed, control lever drives relief valve to close.
Be set to further: described linkage unit comprises the gangbar that to rotate with control lever and be connected and to rotate the dwang be connected with gangbar, dwang rotates and is fixed on casing outside, the axis of gangbar and dwang keeps spacing, make gangbar that dwang can be driven to rotate around its axis when being subject to control lever and pulling, the rotation process of dwang drives relief valve to open or closes.
Compared with prior art, the utility model drives the first locking piece to coordinate with the second phase-locked linking by control lever, and by using the locking spring be connected with the second locking piece, make opening or closing more reliable and secure of chamber door, thus improve the use safety coefficient of locking pressure oven; By using the back-moving spring be connected with the second locking piece, making the unlatching of chamber door more light, also not affecting the reliability of chamber door locking simultaneously; The opening and closing being achieved locking pressure oven door by the link gear between the control lever of the second locking piece and relief valve with and the stable interaction relation that opens and closes of relief valve, guarantee the use safety of whole locking pressure oven.
