Description
Technical field:
The utility model relates to the electric cooker product.
Background technology:
Electric cooker is widely used as the essential household appliances in house, and it frees people from busy housework.After along with people quality of life being proposed higher requirement, the pressure type electric cooker has been come into daily life.Compare common electric cooker product, the rice mouthfeel of the cooking of pressure cooker is better, the time spent is shorter, and energy savings more, thereby very big development space is arranged, but the structure that the pressure cooker of general type adopts is a rotary structure, and promptly the method by rotation makes interior pot be connected with pressure texture.The major defect of its structure is exactly the structure heaviness, and inconvenience operates.The reliability requirement of pressure texture has absolute assurance, and heating plate all is to be fixed on the shell body in addition, and after service time was long, it is not good enough that interior pot and heating plate contact effect, influences the efficiency of heating surface.
Summary of the invention:
The purpose of this utility model is to solve problems such as the pressure texture reliability of pressure cooker product and operation convenience, and a kind of pressure type electric cooker is provided, and is safe and reliable, easy to operate, efficiency of heating surface height.
The technical scheme that the utility model is adopted for achieving the above object is: the pressure type electric cooker, lid is arranged on the housing, pot in housing is built-in, metal framework fixedly is housed in the housing, interior pot frame is on metal framework, an end lock shaft connects the pressure retaining mechanism on the lid, the pressure retaining mechanism is the hinged stiffener of fixed head, latch is equipped with by the latch axle in another termination of stiffener, spring button is housed on the latch, the maintenance pin is housed in the spring, and fixed head is fixedlyed connected with housing, and lid is connected with the housing bearing pin by fixed head.
Below the described lid upper reinforcing plate plate of keeping a public place clean is housed, pressure-regulating valve and pressure protection valve are arranged on the plate of keeping a public place clean, pressure-regulating valve is a pressure ball of placing weight and internal pressure coupling on the steam port, and pressure ball has the guard shield that has opening outward.Pressure protection valve is the compressing tablet of pegging graft on the steam port, and compressing tablet connects spring, and spring pressure equates that with safe pressure spring and compressing tablet place in the housing that has exhaust outlet.
Described metal framework bottom has at least two pilot holes, and pilot hole is built-in with guide finger, and guide finger inserts in the pin-and-hole of heating plate bottom, and box outer has spring to connect heating plate bottom and metal framework.
The utility model modern design when being atmospheric pressure state in the interior pot, just can make latch rotate motion by keeping pin as long as push button, makes latch break away from the edge of interior pot, thereby finishes the action that loam cake is opened, and it is simple, convenient to operate; When in the interior pot pressure being arranged, interior pot will by the edge with the metal framework self-locking that firmly forces together; When only pressure was reduced to safe pressure in interior pot, loam cake could freely be opened.The plate of keeping a public place clean is finished pressure simultaneously and is regulated and two effects of pressure protect, and has the characteristics of compact conformation and convenient disassembly.Because pot will guarantee certain relative altitude position with pressure texture in pressure cooker required, and the position of pressure texture is fixed, the deadweight of pot guarantees the engagement height with heating plate in can not relying on, the utility model is by adjusting engagement height with interior pot to heating plate by three groups of elastic constructions, that is to say that requiring interior pot is flexible with cooperating of heating plate, thereby guarantee the state of its cooperation.
Description of drawings:
Fig. 1 is the utility model structural representation.
The specific embodiment:
Pressure type electric cooker as shown in the figure, lid 10 is arranged on the housing 4, pot 3 in housing is built-in, metal framework 1 fixedly is housed in the housing, interior pot frame is on metal framework, and the metal framework bottom has at least two pilot holes, and pilot hole is built-in with guide finger 20, guide finger inserts in the heating plate 2 bottom pin-and-holes, and box outer has stage clip 21 to connect heating plate bottom and metal framework; An end lock shaft connects the pressure retaining mechanism on the lid, the pressure retaining mechanism is fixed head 17 hinged stiffeners 12, latch 5 is equipped with by latch axle 6 in another termination of stiffener, spring button 8 is housed on the latch, spring button is to be equipped with in the spring 7 to keep pin 9, fixed head is fixedlyed connected with housing, and lid is connected with the housing bearing pin by fixed head.The plate 11 of keeping a public place clean is housed below the lid upper reinforcing plate, pressure-regulating valve 13 and pressure protection valve 14 are arranged on the plate of keeping a public place clean, pressure-regulating valve is a pressure ball 18 of placing weight and internal pressure coupling on the steam port 19, and pressure ball has the guard shield that has opening outward.Pressure protection valve is a grafting compressing tablet 15 on the steam port, and compressing tablet connects spring 16, and spring pressure equates that with safe pressure spring and compressing tablet place in the housing 22 that has exhaust outlet.
When being atmospheric pressure state in the interior pot, just can make latch rotate motion as long as push button by keeping pin, make latch break away from the edge of interior pot, thereby finish the action that loam cake is opened, when in the interior pot pressure being arranged, in pot will firmly forcing together by the edge with metal framework, because the shaft position of latch is forward with respect to the impetus of latch, at this moment the latch structure can produce a rotary torsion square opposite with opening direction under the effect of pressure, must overcome this torsional forces if open loam cake, push the peak torque power that button can produce latch and be decided by that spring structure gets pressure.The peak torque power that spring provides is far smaller than the reverse torque that is produced by pressure, and outer like this bound pair button has great impulsive force that loam cake is opened, thereby realizes auto-lock function.So when only pressure was reduced to safe pressure in interior pot, loam cake could freely be opened.The plate of keeping a public place clean has selected for use two kinds of pressure to guarantee mode simultaneously: counterweight method and SPRING METHOD OF STONE.Pressure ball is pressed in the steam port top during operate as normal, internally carries out sealing in the pot.When reaching designing requirement, the steam pressure in the interior pot pressure ball will be pushed open the beginning pressure release.When pressure was lower than designing requirement, pressure ball will fall after rise sealed steam port automatically, thereby the pressure in the pot is in the designing requirement scope in guaranteeing.In addition, also can by electromagnet with pressure ball from the steam port position push open realize pressure release action make in pressure the pot reduce.At steam port generation abnormal problem, in the time of can not normally opening, pressure protection valve will begin action.When pressure surpassed design pressure, steam will make the spring compression of pressure protection valve, Exhaust Open, beginning decompression protection.In the time of in pressure drops to safe range, spring reset stops pressure release.The heating plate spring structure can be adjusted heating plate on short transverse, the guide finger structure guarantees that heating plate is concentric with metal framework, effectively avoids the different poor fits that cause of relative altitude owing to interior pot.
