The operating procedure of the utility model cooking is as follows:
Take off juice tray 5, in matrix 4, add an amount of water then (1), earlier.
(2), described juice tray 5 is overlayed on the described matrix 4.At this moment, water just flows in the vapour hood 8 by the through hole on the vapour hood 8 13.
(3), steam box 6 stacking above the juice tray 5, in steaming box 6, put into food and cover lid 7 then.
(4), the pot body is overlayed on the pedestal 1, and to guarantee to go up connector 2 be to be in to be connected the state (being the power circuit conducting) that leads to lower connector 3.
(5), connect power supply, according to the kind difference of food, on function control panel 10, select needed function, the utility model then enters duty.
Operation principle of the present utility model is: in the selected good function of oneself wanting on the function control panel 10 and by after confirming, following control circuit board in the pedestal 1 will be exported its instruction, outwards transmit in the mode of infrared or radio wave by the sending and receiving apparatus that is installed on the described pedestal 1, after the sending and receiving apparatus that is installed in described pot body receives this signal, to handle by last control circuit board 12, and allow heater 9 execution heating heat up water, simultaneously thermistor (or bimetal leaf temperature controller) and the electric liquid position detecting device 15 in the induction installation also started working, and detects to heater 9 thermometrics with to the fluctuating range of water in the boiling-house 18 respectively.Meanwhile, last control circuit board 12 also will be tested and detected two kinds of information, send signal by being installed in pot sending and receiving apparatus on one's body.After being installed in sending and receiving apparatus on the pedestal 1 and receiving this signal, the result is shown with the mode of numeral or figure on display unit.(as: show out of Memory such as temperature on the described heater 9, duty.)
When the program time that sets has arrived water in (being that food cooks) or the vapour hood 8 and has been evaporated to lowest water level value set in the electric liquid position detecting device 15, the information that induction installation in the storage cistern 17 will obtain induction, the mode by infrared ray or radio wave passes in the sending and receiving apparatus that is installed on the pedestal 1.When the sending and receiving apparatus on the pedestal 1 received this information, control circuit board sent signal under will giving, and control circuit switches, and cuts off the power supply of heater 9, stops heating, thereby played the intelligent effect of automatic induction and automatic control.
When electric liquid position detecting device 15 because of certain reason, cause it not work, and when having formed heater 9 and being in dry combustion method, after heater 9 dry combustion methods reach uniform temperature, at this moment the induction installation (bimetal leaf temperature controller) that is arranged on heater 9 lower surfaces also can play the effect that control is cut off the electricity supply, and has so also just formed the dual fail-safe anti-dry in the utility model.
The operation principle of above-mentioned anti-dry detection circuit is: after connecting power supply, the upper end of probe 19 is connected with heater 9 as conductor by the water in the storage cistern 17, the other end is connected with last control circuit board 12 by lead 20, thereby forms the loop of a conducting.When the water level in not having water or storage cistern 17 in the storage cistern 17 was lower than the top of probe 19, the anti-dry detection circuit just was in the state of disconnection.At this moment, last control circuit board 12 will send signal, cuts off the power supply in the heater 9, plays the effect that prevents heater 9 dry combustion methods.
In normal use, after the pot body was placed on the pedestal 1, pot body and pedestal 1 can be regarded integrative-structure as, do not have difference with common steamer.Juice tray 5 plays and prevents that swill or dust from entering in the described matrix 4, causes the blocked situation of through hole 13.When needs cleaned the incrustation scale that produces on the heater 9 and be accumulated on one's body greasy of pot, a pot body can take off from pedestal 1 separately, each structure is separated one by one cleaned.
As shown in Figure 4, the madial wall of matrix 4 extends always and exceeds the lower plane of body support plate 14, and forms a downward seam of joining with body support plate 14, has so greatly reduced when cleaning matrix 4, flow into the interior risk of matrix 4 because of causing water because of carelessness.
As Fig. 9, shown in Figure 10, be applied to the embodiment on the steamer of another kind of structure for the utility model.The structure difference of this steamer is: the top peripheral position of pedestal 1 is provided with a ring support 22 that is complementary with storage cistern 17, and matrix 4 has been designed to a structure with storage cistern sidewall 16 these two structures.In use, a described storage cistern 17 that only needs to be provided with connector 3 overlays in the described substrate 1, connector 3 is connected with lower connector 2 gets final product, and stacks juice tray 5 at last, steaming box 6 just can reach user mode.
Pedestal of the present utility model is designed to adopt electric connector to be electrically connected with the pot body, the pedestal that makes steamer can be disconnected from each other with pot body two parts, and in two electric connectors, also be respectively arranged with the sending and receiving apparatus that can carry out wireless transmission and wireless receiving signal or be respectively arranged with radio receiver and wireless launcher on one's body at pedestal and pot, its wireless transmitting and receiving device can be the infrared ray sending and receiving apparatus that mates mutually, also can be the radio transmission receiving system that mates mutually.
The utility model has adopted the each several part structure (comprising matrix, vapour hood, juice tray, steaming box) in the described pot body has been carried out the design of separate type, after particularly described vapour hood is designed to dismountable structure, made things convenient for cleaning, thereby the incrustation scale that has solved effectively on the described heater cleans difficult problem to incrustation scale on the described heater.And the function control panel has adopted the set-up mode of touch-screen switch, the structure (as: glass or plastics) of integral panels can be adopted in the surface of touch-screen switch, need be on panel perforate just can realize the control of function key, not only cleaning is got up easily, has also played the effect of surface waterproofing simultaneously.
