Description
Technical field
The present invention relates to household electrical appliance technical field, refer in particular to a kind of vacuum insulation of electric cooker.
Background technology
Along with popularizing and the renewal of technology of household electrical appliance, the function of a lot of household electrical appliance has obtained perfect, offers convenience to the user.At present, people generally adopt electric cooker to cook, and the function of its convenient insulation is loved by the people, yet, after meal boiled, when entering keeping warm mode, the time one was long, and rice can be along with time and airborne combination with oxygen, breed bacteria will soon flavescence, souring.In view of this, be necessary to provide a kind of vacuum insulation of electric cooker, be applied in ordinary electric rice cooker and the electric pressure, solve this problem.
Summary of the invention
Purpose of the present invention be exactly a kind of reliable in structure of providing at the deficiencies in the prior art part, easy to use, can postpone greatly to be incubated in the vacuum insulation of electric cooker of rice flavescence souring.
For achieving the above object, the present invention includes: the pot body, interior pot, inner pot cover, outer pot cover, the pot cover rotating shaft, pot cover is released the button, the bottom surface heater, side insulation electric heater, pot cover insulation electric heater and guidance panel, be provided with a three-way magnetic valve in pot cover inside, and be connected with the pumping that has bleeding point and gas outlet in the external side of pot, first opening of this three-way magnetic valve is communicated with interior pot cavity, its second opening is communicated with the bleeding point of pumping, its the 3rd opening be positioned at the relief hole that outer pot covers and be communicated with, also be provided with the switch of control three-way magnetic valve and pumping work outside on the pot cover.
After adopting said structure, somewhere at pot cover, design a three-way magnetic valve, and external pumping of magnetic valve and relief hole after meal is cooked, start magnetic valve, and startup pumping, air in the pot is extracted out, made the vacuum state that causes in the pot to a certain degree, thereby effectively make the rice in the insulation postpone flavescence and souring.The present invention has reliable in structure, easy to use, time that has prolonged the rice flavescence souring in the insulation, the characteristics that can be applicable to ordinary electric rice cooker and electric pressure.
Description of drawings
Fig. 1 is the cross-section structure principle schematic of electric pressure embodiment one of the present invention.
Fig. 2 is the cross-section structure principle schematic of ordinary electric rice cooker embodiment two of the present invention.
Fig. 3 is the partial enlarged drawing of the three-way magnetic valve among Fig. 1 and Fig. 2.
The specific embodiment
As accompanying drawing 1～shown in Figure 3, the present invention includes: pot body 10, interior pot 11, inner pot cover 12, outer pot cover 13, pot cover rotating shaft 14, pot cover releases the button 15, bottom surface heater 16, side insulation electric heater 17, pot cover insulation electric heater 18 and guidance panel 19, be provided with a three-way magnetic valve 20 in pot cover inside, and be connected with the pumping 30 that has bleeding point 31 and gas outlet 32 in pot body 10 outsides, first opening 21 of this three-way magnetic valve 20 is communicated with interior pot 11 cavitys, its second opening 22 is communicated with the bleeding point 31 of pumping 30, its the 3rd opening 23 is communicated with relief hole 131 on being positioned at outer pot cover 13, also is provided with the switch of control three-way magnetic valve 20 and pumping 30 work outside on the pot cover 13.Described electric cooker is an electric pressure, its inner pot cover 12 and outside also be communicated with a pressure release passage 40 on the pot cover 13, at the outer vent place of this pressure release passage 40 relief valve 41 is housed.Described three-way magnetic valve 20 includes first opening 21, second opening 22, the 3rd opening 23, valve body 24, two Ball valves 25 and two electromagnet 26, two Ball valves 25 are installed in second opening 22, the 3rd opening 23 places respectively, and two electromagnet 26 are installed in the both sides of second opening 22 and the 3rd opening 23 respectively.Described three-way magnetic valve 20 is arranged on the bottom of inner pot cover 12.Below described pot body 10 sides, pot cover rotating shaft 14, be connected with the pumping case 50 that is used to install pumping 20.The switch of described control three-way magnetic valve 20 and pumping 30 work is arranged on pot cover and releases the button in 15.
During use, shown in figure one, when adding rice in the electric pressure when beginning to heat, the bleeding point 31 that the three-way magnetic valve 20 of design in pot cover controlled relief hole 131 and pumping 30 all is in closed condition, guarantees not pressure release; After meal boils, open relief valve 41, wait let out pressure after, close the relief valve of opening 41; Press pot cover again and release the button 15, trigger gauge tap, open second opening 22 of three-way magnetic valve 20, start the pumping 30 of pot body 10 sides simultaneously, the air in the interior pot is discharged by bleeding point 31; When reaching certain negative pressure, second opening 22 and the 3rd opening 23 of three-way magnetic valve 20 are closed automatically, form vacuum state to a certain degree in making in the pot 11, make the rice delay flavescence in the insulation, the time of souring; In the time will getting rice, press pot cover again and release the button 15, the 3rd opening 23 of three-way magnetic valve 20 is opened, connect relief hole 131, air is entered in the cavity of interior pot 11, inner pot cover 12 and outer pot cover 13 just can be opened.When inner pot cover 12 and outer pot cover 13 cover, when pressing this button again, pumping 30 is automatically starting just, exhaust pot interior air after, stop automatically.So recycle, very convenient.
Embodiment shown in the figure two for another example, when adding rice in the ordinary electric rice cooker and begin to heat, relief hole 131 in the outer pot cover 13 and the 3rd opening 23 of three-way magnetic valve 20 are in open state, avoid pressure excessive.After meal boils, press pot cover 15 the 3rd openings 23 that just can close three-way magnetic valve 20 of releasing the button and connect relief holes 131, open second opening 22 of three-way magnetic valve 20 simultaneously and connect bleeding point 31, and start the pumping 30 of pot body 10 sides, the air in the interior pot cavity is discharged.When reaching certain negative pressure, three-way magnetic valve 20 is closed second opening 22, and the bleeding point 31 of closed pumping 30 forms vacuum state to a certain degree in pot 11 bodies in making; Rice in the insulation then postpones time of flavescence, souring widely; In the time will getting rice, press pot cover again and release the button 15, can open relief hole 9, air is entered in interior pot 11 bodies, inner pot cover 12 and outer pot cover 13 just can be opened.When inner pot cover 12 and outer pot cover 13 cover, when pressing this button again, pumping 30 is automatically starting just, exhaust pot interior air after, stop automatically.So recycle, very convenient.
In sum, the present invention has improved the deficiency of existing electric cooker function, and rice flavescence, souring in can postponing greatly to be incubated have characteristics simple and reliable for structure, easy to use.
