Abstract

PURPOSE:To quickly inform abnormality of a cooker, by detecting various abnormal states of food to be cooked by control means thereby displaying an abnormality state division on a display apparatus. CONSTITUTION:The control means detects the fact that the difference between the food temperature and the original temperature is not exceeding a predetermined value when a certain period has passed after the start of the cooking so that the fact that the object to be heated is out of the detecting field 23 of an infrared sensor 12 is judged. Further if the control means detects the fact that the chopper count within a certain period is out of a prescribed value, it is detected as a rotational abnormality of an infrared temperature detecting section chopper plate 14. Based on the detection of these abnormalites, the control mean displays the number of the abnormality division in stead of the number of key division displayed on the displaying section. By constituting the program of the control means 18 in this manner, an abnormal operation can be quickly informed.

The feature of this embodiment is that the control means electronically detects the member's wealth S which is exclusive to ypo@11.

The abnormal state ill is a state in which the object to be heated is out of the detection field #Q (11511) of infrared rays y+aa. In this state, as Hiro has already stated, normal rotational control cannot be carried out.

The second abnormal state is the deWfA of one step outside line temperature and gas.
[14#m transfer wealth*lkl KoL-1t condition.

In this case as well, normal maple power cannot be carried out. The feature of i12 of this embodiment is that the control means (11 is a display means; "C" indicates each abnormal state of the first and second abnormal conditions). - The 5th 1 is displayed on the display means (31), and the abnormal state symbol "I!1-" of iJl is displayed in place of the serial number for pressing the above-mentioned key t'K11l. 5G shows that the second abnormal condition ■ symbol "Otori 2°" is displayed.

Figure 1116 shows the control program of the control means a field.

This program is also similar; ROMt of control means (2)
;It is stored.

As mentioned above, press the heating key 15) to press the start key ts) to press the v button. a--Execution of the program starts.

First, at P1 step 1, the infrared temperature detection section 3I starts to overshoot. Namely, Soita I, Photointerface 1! -, etc. are supplied, and the temperature deviation amount begins to be output from the temperature detection Il (to).Then, in step P2, the contents of 1A are displayed.

Sho f ii y Att? VIha'/114 hand a
It occupies one range of RAM in n. At step P5, the control means a takes in the output of the temperature detection section (the temperature detection section). This output is 1iilK at the start of one cycle of the heated object, and therefore the control means *Qa stores this as the initial temperature.

Next, in P4 step 11, the serial number corresponding to -151 in the heating menu specified by two people is displayed on display hand J1 (3
3 (2) is displayed, and microphone aam control is performed in step P5. This 81 sister is to turn on and off the magnetron 2 times 2 2 4 t' according to the microwave output of the corresponding heating 1a gram.pLL-26 In the step, the control means (11 detects the temperature of the object to be heated t' through the temperature detection 5Cllt-
At P7 day y1, it is determined whether the temperature of the heated object has reached the corresponding finishing temperature of 10 gf. In the case of 11jil, P8 stage moves only 1 step.

In P-6 sde 1g, after P5 sde y1, that is, microphone a*m
It is determined whether the elapsed time after the start of tih is exactly 1 minute or not, and if it is 1 minute, it is set to P9, and if not, it is set to P9.
Move on to step 10. ? ? In step P6, it is determined whether or not the difference between the temperature of the heated object read in step 1 and the initial temperature read in step 13 is greater than a predetermined amount, and if it is, the process moves to step P10. In step P10, the controlling means is the output A# of photointerrupter 4 of the temperature detection section @.
The pulse is read quickly, and the above-mentioned TeW Tupakawanta is turned up with that pulse.

In the following P11 step, it is checked whether 2 seconds have elapsed in P4 step 4, and if it has not elapsed, P4 snap r-1
Also, if you have already passed the exam, move on to P12 Sude 1 Pro.

In Step 1 of P12, it is determined whether or not there are ll1lr-people whose contents in the above text are scheduled, and if there are, in Step P1jS, the contents of the above Te" 11 Bakakun! content tgutsu 1 are done, and then step 1 is executed. Return to

Therefore, after starting -mll, the program is P4~Pa.

Each step of Plo, Pll, and P4 is cycled, and during the cycle, at z seconds 11, the process moves to P12. If the temperature detection part (to) is not rotating normally, the contents of the above 2 seconds of noise (the content of the temperature detection part (to)) will not be normal as expected. Therefore, every 2 seconds mentioned above (after moving to the second P12 day y1, it returns to the second P44 via the 715 snap).

Also, during the above circulation, P is activated only when 1 minute has passed after snmnm.
Moving on to step 9, the object is within the infrared detection range S@
If the temperature is sufficiently within, the difference between the determined temperature of the heated object and the above-mentioned initial temperature should be larger than the expected amount when 1 minute has passed.

At this time, the process moves to the PIG step.

From then on P4 to P8. Each step of P1G, P11, P4 is cycled, WP12, P1 black step is passed every 2 seconds, and then when the temperature of the heated object reaches the expected finishing temperature of 5Ijl, from P7 step, P14 step 1C-transfer%
In this step, the temperature detection part l and the magnet 111 are fired m5ii
The drive of ns is stopped and the process ends once and then P15.
After the PDP is driven for a predetermined time (for example, 2 seconds) in the step, it enters the standby state. The standby state means setting the internal layer of the control means and pressing the new heating menu designation key 15).
It is to be noted that the P4 day yyvt<9 has elapsed until moving to the P14 step 1, so the display means (3) continues to display the number 7, 221, and $ during this time.

Now, as mentioned above, when the first abnormal condition exists, that is, when all or most of the heated object is not within the infrared detection field of view, Even after one minute has passed, the difference between the temperature of the heated object and the above-mentioned initial temperature is smaller than the expected normal difference, so the process moves from step P9 to step P16.

In P14 day y1, other areas of the ham wing are displayed.
The data representing 11° is written in the step t=-, and then (after the tin layer similar to step I'14 is made at step P18 and the step is stopped, each step 1 of PI3 and P21 is written.
The honey circulates. During this cycle, the contents of the e-star are displayed in step P19.

"Expletive 1'-" is displayed on the display means (↓), and the key input from the life board (4) is performed at step P20.

Therefore, when the operator recognizes the displayed contents of the display means 1 and t, he learns of the sl abnormality St, and when he operates the keyboard (cancel key (7) of 4), the operator enters the standby state. Within the infrared detection range of heated objects (after pressing again, press the heating menu designation key (51 and -go-mimaichi (at') to select i.

Further, as described above, when the 26th member is in a normal state during the further execution, that is, when there is abnormal rotation of the lever 1 pa @@a4, the above Tei! Since the amount of cuffing in 2 seconds is not within the planned range, P12
Move from step to P17 step 1.

In step P17, the above display register C-feature = 12.
t-table data is written, and thereafter P18-P is written in the same way.
21 days have passed. "12-" is displayed on the 19th display means (gloss), and the system waits for the input of the cancel key (7).

Therefore, the operator must

Press the cancel key (4) and (7) to place the electronic vyp in a standby state (along with contacting the repair company).

In addition, as another embodiment, a voice synthesis means is added and the first. The second abnormal condition, along with the above visual display (;.

Alternatively, an auditory message such as "Please hide the object in the center of the heated object" or "Please contact a repair company" may be displayed.

Furthermore, it is of course possible to detect not only two abnormal states but also more abnormal states and display them as one.

Furthermore, a specific menu for detecting the first abnormal state,
That is, only the menu in which the object is likely to fall out of the infrared detection field of view (two menus may be used).

Unfortunately, the present invention uses an electric heater as a heat source, not just a microwave oven (GRC). It is also effective for utensils.
