Abstract
The utility model relates to an electric rice cooker using a multi-purpose timer with a single driving plate. The utility model belongs to the improvement of a timing electric rice cooker and is characterized in that a timer adopts a single shaft which is sheathed with the single driving plate and a single drop pit wheel. A temperature controlled automatic heat reducing circuit is composed of a heat-sensitive element K3 which can be disconnected at 85 DEG C and an intermittently closed G and E reed contact switch in parallel. Because the components of the timer are changed from an original double shaft, a double driving plate, a double drop pit wheel into the single driving plate, the single shaft and the single the drop pit wheel, thus, the electric rice cooker has the advantages of simple structure and convenient and visual operation. The intermittent switching of G and E reeds is used for reducing heating power consumption.
Description
The utility model relates to a kind of improvement of timing electric cooker.
The 95244571.9 plesichronous multifunctional electric rice cookers that economize on electricity by my application have obtained on market and have applied, yet shortcoming is to adopt two dial timing switches, complicated operation, and users are difficult for grasping.
The purpose of this utility model is in order to overcome the shortcoming of prior art, a kind of single dial multipurpose timer electric cooker to be provided.
The technical solution of the utility model is that it includes pot body, heater element RR, magnet steel temperature limit switch K1, warmer K switch 2, timer and temperature control reduce the caloric value circuit automatically, the reed contact A of timer and B respectively with 1 of the magnetic steel temperature limiter K1 of warmer K switch 2 and hilted broadsword dibit, 2 contact parallel circuitss and temperature control reduce 1 of caloric value circuit and magnetic steel temperature limiter K switch 1, after being in series, the series circuit of 3 contacts connects with heater element RR jointly again, timer motor M one end connects power supply, the other end is connected with reed contact D, is characterized in being set with single dial on the timer employing single axle, single gear, single pit wheel construction.
The advantage of this electric cooker is simple in structure, and is easy to operate directly perceived, asks that the disconnected heat energy that adds reduces power consumption, popular with users.
The utility model embodiment is described further in conjunction with the accompanying drawings.
Fig. 1 is the pit wheel of embodiment 1, spring combination figure,
Fig. 2 is the pit wheel of embodiment 2, spring combination figure.
Embodiment 1:
By shown in Figure 1, timer has only an axle 5 single dial 3 of suit thereon, single pit wheel 19, single final stage gear 56, reed contact A with by 1 of the magnetic steel temperature limiter K switch 1 of insulation K switch 2 and hilted broadsword dibit, the circuit that 2 contacts are in parallel is in series, reed contact B with reduce 1 of caloric value circuit and magnetic steel temperature limiter K switch 1 by heating element R automatically with the temperature control that is formed in parallel with the temperature-sensitive element K3 that can disconnect again after diode d connects to 85 ℃, 3 contacts are in series, and then connect with heater element RR jointly, timer motor M one end connects power supply, the other end is connected with reed contact D, and reed contact H is connected with indicator light L2.
If need cook immediately, do not need to stir the timer dial, as long as press K1, make 1 of K1,2 contacts are connected, if will regularly cook, then press K1 and make 1,2 contacts are connected, and stir dial to the time that need cook, this moment, reed boss 15 was controlled on the e to the outer of pit 19, CDFBH connects, and indicator light L2 is bright, and the work of timer motor M is promptly regularly left, this moment, AC connected, CD disconnects, and electric cooker is by the high-power heating of heater element RR, in the time of 103 ℃, 1 of K1,2 disconnect, 1,3 connect, and by the K2 insulation, temperature-sensitive element K3 disconnects when being higher than 85 ℃, therefore in the process of cooking, the timer motor M is not all worked.Cooking congee, during the multi-functional cooking of Baoshang, 1 of K1,3 connect, carrying out plesichronous this moment sets, i.e. regularly starting and regularly pass, when boss 15 pushed the outer c part of pit wheel 19, reed contact CD connected, and AC disconnects, BF disconnects, motor M work, one behind the timing proceed-to-send, and reed boss 15 falls into the groove b of pit wheel 19, and reed CDFB is connected, by temperature-sensitive element K3 by the high-power heating of heater element RR, the motor M running, when heating-up temperature was higher than 85 ℃, K3 disconnected, this moment is by diode d and heater element R, the heating of RR series connection small-power, until regularly closing, reed boss 15 falls into pit race a, and CD disconnects, motor M does not turn round, and this moment, AC connected by 2 insulations of warmer K switch.
Embodiment 2:
By shown in Figure 2, different is by heating element R with embodiment 1 is to change into adopting temperature-sensitive element K3 and being interrupted closed E with the temperature control caloric value circuit that is formed in parallel with temperature-sensitive element K3 again after diode d connects, G reed contact switch in parallel forms, operation principle is just had any different when timing is closed, when regularly closing, reed boss 15 falls into pit race b, this moment, CDBF connected, motor M work, by the high-power heating of temperature-sensitive element K3 heater element RR, the motor M running, when heating-up temperature is higher than 85 ℃, K3 disconnects, at this moment, motor M drives the compound cam actuating spring contact G that is provided with on the train, it is that the circuit heater element RR that connects again is interrupted heating that E is interrupted temperature control heating that switch forms behind the series diode again.
Claims (4)
1, a kind of pot body that includes, heater element RR, magnet steel temperature limit switch K1, the warm device K switch 2 of stewing, timer and temperature control reduce the electric cooker of the single dial multipurpose timer of employing of caloric value circuit automatically, the reed contact A of timer and B respectively with 1 of the magnetic steel temperature limiter K1 of warmer K switch 2 and hilted broadsword dibit, 2 contact parallel circuitss and temperature control reduce 1 of caloric value circuit and magnetic steel temperature limiter K switch 1, after being in series, the series circuit of 3 contacts connects with heater element RR jointly again, timer motor M one end connects power supply, the other end is connected with reed contact D, it is characterized in that, described timer adopts the single dial of suit on the single axle, single final stage gear, the structure of single pit wheel.
