Description

The heating means of baking machine, the heater of baking machine and baking machine

Technical field

The present invention relates to baking machine technical field, in particular to heating means, the heater of a kind of baking machine and a kind of baking machine of a kind of baking machine.

Background technology

Baking machine the most on the market; when preheating completes; after putting into food; the baking tray temperature of baking machine can drastically reduce (as shown in Figure 1); and the temperature controller (or temperature detector) in baking machine can not sense the decline of temperature immediately; generally having the delay of 10 seconds 30 seconds, thus cannot at once notify that food is heated by heating unit, this makes the temperature of baking tray just start heat foods after reducing further.And the concrete heating process of its baking machine includes: step 102, when baking machine has preheated, put into food；Step 104, the temperature controller in baking machine starts to detect in real time the temperature of baking tray, and judges whether baking tray temperature T detected is more than T0 (T0 generally takes 170 DEG C to 210 DEG C), if it is, perform step 106；Heat if it is not, then continue baking plate, and re-execute step 104；Step 106, when baking tray temperature T being detected more than T0, stops heating baking tray；Step 108, it is judged that whether baking tray temperature T that temperature controller detects is less than T1 (T1 generally takes 160 DEG C to 180 DEG C)), if it is, perform step 110；If it is not, then perform step 106；Step 110, when baking tray temperature T detected is less than T1, continues baking plate and heats.

But, current this heating means can cause food cooking time of baking machine long due to the response delay of temperature controller, further, since cannot effectively control the temperature of upper lower baking disk respectively, mouthfeel, outward appearance are the best because water loss is too much to further result in food.

Therefore, how to solve the heating delays problem postponing due to temperature controller temperature-sensitive and the temperature of upper lower baking disk effectively cannot being controlled and cause, and then the loss of minimizing food moisture, improve the mouthfeel of food, become technical problem the most urgently to be resolved hurrily.

Summary of the invention

It is contemplated that at least solve one of technical problem present in prior art or correlation technique.

To this end, it is an object of the present invention to propose the heating means of a kind of baking machine.

Further object is that the heater proposing a kind of baking machine.

A further object of the present invention is to propose a kind of baking machine.

For achieving the above object, embodiment according to the first aspect of the invention, propose the heating means of a kind of baking machine, including: after the preheating of described baking machine, when the temperature of the baking tray of described baking machine maintains between the first preset temperature and the second preset temperature, according to the triggering signal received, described baking tray is compensated heating；After described compensation heating process terminates, the temperature controller of described baking machine detects upper baking pan and/or the real time temperature of lower baking disk of described baking machine, and determines whether to continue to heat described upper baking pan and/or described lower baking disk according to the real time temperature of described upper baking pan and/or the real time temperature of described lower baking disk.

nullThe heating means of baking machine according to an embodiment of the invention，In baking machine after preheating，When baking tray temperature maintains (usually 160 DEG C-210 DEG C) between the first preset temperature and the second preset temperature，Heating is compensated by carrying out baking plate according to the triggering signal received，When food can be overcome to be placed into baking tray，Temperature controller in baking machine cannot sense the decline of baking tray temperature and the heating delays problem brought in time，Thus realize the compensation to food and heat，Additionally，By reasonably control this heating process (such as: reasonably control force heating time or heating-up temperature) can shorten compensation heat time heating time，Reduce the loss of food moisture，The most important thing is become dry faster through the surface of so food of heating，Require time in the heat transfer of the epidermis of food to food，Certain moisture is also possessed in making food，Certainly，After compensation heating process terminates，Determined whether respectively by the real time temperature of the real time temperature according to upper baking pan and/or lower baking disk to continue upper baking pan and/or lower baking disk are heated，May further ensure that the loss (omiting) loss more than the moisture of food internal layer of the moisture of the exocuticle of food，And then make the crisp internal layer of food appearance that grillING goes out soft，And prevent the upper epidermis of food to be scorched.It addition, by reasonably controlling this heating process, the loss that typically can make the moisture of the exocuticle of food is 20%-70%, internal layer moisture loss 7%-15%.

According to one embodiment of present invention, described triggering signal is sent by with one or a combination set of lower component: CPU, triggering switch, heater switch.
