Abstract
The invention discloses a temperature control method for an upper cavity of an electric oven. The electric oven comprises a control chip, a lower cavity and the upper cavity, wherein heating bodies and temperature probes are arranged in the lower cavity and the upper cavity; the control chips are used for receiving the temperature measurement signals of the two temperature probes; the heating body of the upper cavity works as the upper cavity starts working, the control chip sets an initial buffer temperature Tk, the heating body of the upper cavity stops heating when the temperature of the upper cavity reaches the initial buffer temperature Tk, the heating body of the upper cavity starts to work once again after a time t1 and the heating body of the upper cavity is used for continuously and stably heating the upper cavity in a circulating mode in a manner of working-stopping intermittent heating. The temperature control method disclosed by the invention can avoid influence on a temperature control process over the upper cavity due to the various working states of the lower cavity, and can achieve precise control over the temperature of the upper cavity regardless of whether the lower cavity works or not; in addition, the method disclosed by the invention, in a mode of setting the initial buffer temperature, can effectively avoid the occurrence of a high-temperature peak, so that the initial heating process of the upper cavity, even through being affected by the lower cavity, can achieve normal transition.
Description
Technical field
The present invention relates to a kind of temperature control method of electric oven product, particularly a kind of epicoele temperature control method with the electric oven of upper and lower cavity structure.
Background technology
Electric oven is the electric heating appliance that the radiant heat utilizing heating to send carrys out baked goods, and we can make roast chicken, roast duck, baking bread, cake etc. to utilize it.In order to the requirement of satisfied difference culinary art, there is a kind of bicavate electric oven at present on the market.As shown in Figure 1, the cavity of resorption of this kind of electric oven, as main heating chamber, is generally used for and realizes normal electric heating function, and epicoele is as auxiliary heating chamber, be then generally used for the functions such as boiling.Because epicoele and cavity of resorption are pressed close to mutually, both can carry out heat transfer, and especially for epicoele, when cavity of resorption works, cavity of resorption heats the high heat produced when being transmitted in epicoele, and the temperature of epicoele can be greatly affected.Current epicoele temperature control method is generally all arranged independent of cavity of resorption, because the duty of cavity of resorption when epicoele starts is unknown, therefore adopts the temperature control effect of this independent temperature control method poor, can not carry out accurate temperature controlling to epicoele.In addition, epicoele is when initial start is heated, it generally can produce a high temperature spike, particularly be subject to lower cavity temperature when affecting, this high temperature spike can be very outstanding, this high temperature spike can cause the instability of calandria work, therefore how to avoid this high temperature spike to be also one of epicoele temperature control problem that must solve.
Summary of the invention
For the problems referred to above, the invention provides and a kind ofly accurately can control upper cavity temperature and effectively can overcome the temperature control method of the electric oven epicoele of initial high-temperature spike.
The technical scheme that the present invention adopts for its technical problem of solution is:
A kind of temperature control method of electric oven epicoele, this electric oven comprises control chip, cavity of resorption and is arranged on cavity of resorption cavity of resorption heat by conduction can be utilized to carry out the epicoele heated, calandria and temp probe is respectively provided with in cavity of resorption and epicoele, it is characterized in that described control chip receives the temperature measurement signal of two temperatures probe, after epicoele starts heating, epicoele calandria works, control chip setting initial buffer temperature T
