Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an oven toaster for cooking toast, cake and the like.

[0002]

2. Description of the Related Art Factors necessary for baking bread, such as four-piece and six-piece pieces, are the temperature inside the refrigerator and the radiant heat of the heater. In particular, the radiant heat of the heater is an important factor in terms of preventing the evaporation of water in the bread by giving the surface of the bread a fox-shaped focal point.

As a conventional oven toaster of this type, for example, the one disclosed in Japanese Patent Laid-Open No. 4-92616 can be cited. In the conventional oven toaster shown in this publication, the heating and cooking time is set in correspondence with the heating stop time before the start of cooking, that is, the rest time. When the rest time is long, the heating time is set long. However, when the rest time is short, the heating time is set to be short.

[0004] In addition, as a control of the heating and cooking time, there is a heating and cooking device (for example, a microwave oven) other than the oven toaster, in which the heating and cooking time is set according to the temperature in the refrigerator.

[0005]

In the conventional oven toaster, the heating and cooking time is set according to the rest time as described above. Therefore, when the toast cooking is continuously performed, the heating oven is heated. The internal temperature continues to rise, and the internal temperature exceeds 300 ° C., which causes the main body to heat up, and there is a problem in safety. Furthermore, since the temperature inside the oven becomes abnormally high, the water in the bread also easily evaporates. Therefore, when continuous toast cooking was performed, it was not possible to obtain a delicious toast containing water and having a dry surface. .

In addition, a control system for setting the heating and cooking time corresponding to the temperature inside the chamber, which is used in heating cookers other than the oven toaster, is frequently used in continuous cooking such as in the oven toaster with a pause. Even if it is simply applied to a so-called heating cooker, highly accurate control of the cooking time cannot be expected. That is, even if the temperature inside the refrigerator is the same,
If the length of the rest time before the start of cooking is different, the temperature rise inside the refrigerator after the start of cooking will change.

In view of the above points, the present invention provides an oven toaster that is highly safe even when continuous toast cooking is performed, can perform heating cooking time control with high accuracy, and can obtain a delicious toast. To aim.

The heating time setting means 28 is set to 0. When outputting from the standard heating time selection means 26 to the alarm 27, the user is told, for example, by voice, "The temperature inside the chamber has risen, please wait for a while."
It is preferable to send a message such as.

Next, the operation of the oven toaster according to the first embodiment will be described based on FIGS. 4 to 7 with reference to FIGS. 1 to 3. First, as an initial setting, the door 3 of the main body 1 is opened, two pieces of bread such as six slices are placed on the grill 7 in the heating chamber 2, the door 3 is closed, and then the baking color adjustment dial 11 is rotated. Then, a desired burn color is set from the burn color densities 1 to 7 (here, the scale is set to "4"), the start / stop key 13 is pressed, and the control device 16 is driven. If the start / stop key 13 is pressed firmly, the indicator lamp 14 lights up to inform that heating is in progress.

In the control device 16, the start / stop key 13
When is pressed, it is determined whether or not the start / stop key 13 is ON (step 111). If it is ON, the inside temperature Th is measured (step 112), and the measured inside temperature Th is preset. The temperature T1 (150 ° C.) is compared with the temperature T1 (150 ° C.) to determine whether the internal storage temperature Th is equal to or lower than the temperature T1 (150 ° C.) (step 113). If it is the first toast cooking, since the inside of the refrigerator is at room temperature (less than 30 ° C.), the process proceeds to step 114. In step 114, it is determined whether or not the sleep timer 19 is operating. If it is the first toast cooking, the pause timer 19 is in the initial state (reset state), and thus the process proceeds to step 115. In step 115, the reference heating time selection means 26 uses the reference heating time table to calculate the reference heating time Tc (1) based on the inside temperature Th and the burn color density 4 measured in step 112.
80 seconds). Next, correction is performed based on the rest time of the reference heating time Tc (step 116). At this time, the pause timer 19 is in an initial state, that is, a state where 5 minutes or more have elapsed, so the heating time setting means 28 selects a correction value of 0 second from the correction value table, and this correction value (0 second)
The reference heating time Tc is corrected by and the corrected reference heating time is set as the actual heating time t1 (step 117). That is, in the case of the first toast cooking, the correction is not substantially performed, and the reference heating time selection means 26 is used.
The reference heating time Tc (180 seconds) selected by is the set heating time t1 as it is.

When the heating time t1 is set, the heating control means 23 is activated to energize the heaters 5 and 6 to start heating (step 118), and at the same time, the heating timer 24.
Operates to integrate the heating time t (step 119).
The accumulated heating time t is constantly monitored by the heating time determination means 25 and compared with the set heating time t1 (step 120). If the comparison result is not t ≧ t1, the heating time is integrated, that is, the energization of the heaters 5 and 6 is continued, and if the comparison result is t ≧ t1, the heating control means 2
3 stops energizing the heaters 5 and 6 (step 12
1) Activate the pause timer 19 (step 12)
2).

The pause time tn accumulated by the pause timer 19 after the heater is stopped is constantly monitored by the pause time determination means 21 and compared with a preset upper limit pause time of 5 minutes (step 123). The comparison result is tn ≧ 5
If it is not a minute, it is judged whether or not the start / stop key 13 is turned on (step 124). If it is not turned on, the process returns to step 123, and if it is turned on, the process returns to step 112. That is, until the rest time tn exceeds 5 minutes,
The integration of the pause time is continued while it is constantly determined whether or not the start / stop key 13 is turned on. Step 12
If the comparison result is tn ≧ 5 minutes in 3, the process returns to the initial state (step 125) and the process ends. The above is the processing operation in the first toast cooking.

Next, when the second toast cooking is continuously performed within 5 minutes (here, 30 seconds later) after finishing the first toast cooking under the same baking color condition as the previous one. Will be described. First, in step 124 of the processing operation in the first toast cooking, it is determined that the start / stop key 13 is turned on, and the process proceeds to step 112 while the integration of the down time is continued. The internal temperature Th (here, 70 ° C.) is measured. Then, in step 113, the inside temperature Th is equal to the temperature T1.
It is determined that the temperature is (150 ° C.) or lower, and step 11
Go to 4. Since it is determined in step 114 that the sleep timer 19 is operating, the process proceeds to step 126. In step 126, the pause timer 19 is stopped. Next, the correction value (-30 seconds) is selected and set based on the pause time tn (30 seconds) at this time (step 127), and after that, the pause timer 19 is reset (step 128), and then the processing is performed. Move to step 115.

In step 115, the reference heating time selection means 26 selects the reference heating time Tc (160 seconds) from the reference heating time table based on the inside temperature Th (70 ° C.) measured in step 112 and the burn color density 4. To do. Next, in step 116, the reference heating time Tc (160 seconds) is corrected (160-30 = 130 seconds) based on the correction value (-30 seconds) according to the rest time tn (30 seconds), and step 1
The actual heating time t which is the reference heating time after correction in 17
1 (130 seconds) is set. Then, based on the set heating time t1 (130 seconds), the heating control means 23
Performs the second toast cooking under the same heating control as in the first toast cooking. The continuous toast cooking from the third time onward is also performed by the same processing operation as described above.

As the number of continuous toast cooking increases,
The internal temperature Th rises. The inside temperature Th is equal to the temperature T1 (1
50 ° C.), the temperature inside the refrigerator Th
Is determined to be equal to or higher than the temperature T1 (150 ° C.), the alarm 27 notifies that the internal temperature has increased (step 129), and the process proceeds to step 123. That is, until the rest time tn exceeds 5 minutes,
While continuously determining whether the start / stop key 13 is turned on and whether or not the internal compartment temperature Th has become equal to or lower than the temperature T1 (150 ° C.), the integration of the down time is continued, and the internal compartment temperature Th becomes the temperature T1. The output of the heating amount from the heating amount determining means 22 is stopped until the temperature falls below (150 ° C.).

As described above, in the oven toaster according to the first embodiment, toast cooking is performed based on the heating amount according to the set color value, the temperature inside the oven at the start of cooking, and the rest time before the start of cooking. , Even if continuous toast cooking is performed, heating cooking time control can be performed with high accuracy,
You can get delicious toast.

Further, the heating amount determining means 22 selects and sets a reference heating time corresponding to the set color value and the inside temperature from the reference heating time table, and sets the set reference heating time before starting cooking. Since it is configured to determine the heating amount by correcting with the correction value according to time, for example, the inside of the refrigerator after starting cooking that occurs when the temperature in the refrigerator is the same and the length of the rest time before starting cooking is different It is possible to respond to changes in the temperature rising tendency.

Further, since the heating amount determining means 22 is configured to stop the output of the heating amount when the internal temperature exceeds a predetermined value (for example, 150 ° C.), even if the number of continuous toast cooking increases. , It is possible to prevent the temperature of the main body from becoming abnormally high, which enhances safety.

Further, since the heating amount determining means 22 is configured to set the correction value to 0 when the rest time before the start of cooking exceeds the predetermined value, continuous toast cooking is performed at intervals of 5 minutes or more. When it is performed, the same control as the first toast cooking, that is, the control from the initial state can be performed even in the second and subsequent continuous toast cooking. That is, if the pause time after the heater is stopped is 5 minutes or more, the initial state can be surely returned.

Embodiment 2. FIG. 8 is a block diagram showing the configuration of the control unit of the oven toaster according to claim 6 of the present invention,
FIG. 9 is an enlarged front view showing the operation section, and FIG. 10 is a flow chart for explaining the operation of the control section.
In each drawing, the same reference numerals are given to portions corresponding to the above-described first embodiment.

In the oven toaster according to the second embodiment, a manual heating key 31 for forcibly heating by manual operation is provided on the operation portion 9 provided on the lower front surface of the main body so that the user can operate the grill through the transparent window of the door. This allows the toast cooking up to the desired baking color by manual operation while observing the bread of No. 5, and re-energizing the heaters 5 and 6 only while the manual heating key 31 is kept pressed after the heaters 5 and 6 are stopped. It is made possible to do. The other configurations are the same as those in the first embodiment.

Next, the operation of the oven toaster according to the second embodiment will be described based on FIG. 10 with reference to FIGS. 8 and 9. The operations of steps 211 to 222 are the same as steps 111 to 122 of the first embodiment.
The operation is the same as that of step 228 to step 2
Since the operation of 33 is also the same as the operation of steps 124 to 129 of the first embodiment, the description of the operation of each of these steps will be omitted here, and the operation of steps 223 to 227, that is, after the heaters 5 and 6 are stopped, will be described. The operation will be mainly described.

First, when the automatic toast cooking is finished, the energization of the heaters 5 and 6 is stopped (step 221), and the pause timer 19 is activated (step 222), the pause time tn accumulated by the pause timer 19 is calculated. It is constantly monitored by the pause time determination means 21 and compared with a preset upper limit pause time of 5 minutes (step 223). If the comparison result is not tn ≧ 5 minutes, it is determined whether or not the manual heating key 31 is turned on (step 224), and if it is turned on, energization to the heaters 5 and 6 is restarted (step 22).
5). Next, it is determined whether the manual heating key 31 is in the ON state, that is, whether the user keeps pressing the manual heating key 31 (step 226). If it is not in the ON-state, that is, if the user releases the manual heating key 31, the power supply to the heaters 5 and 6 is stopped (step 227) and the process returns to step 223. If it is determined in step 224 that the manual heating key 31 is not turned on, it is determined whether the start / stop key 13 is turned on (step 22).
8) If not ON, the procedure returns to step 223, and if it is ON, the procedure returns to step 212 and shifts to the processing operation of the second continuous toast cooking similar to the above-described first embodiment.

That is, until the rest time tn exceeds 5 minutes, it is always determined whether the manual heating key 31 is turned on or whether the start / stop key 13 is turned on, and the rest time is integrated. Is continued. Then, when the comparison result is tn ≧ 5 minutes in step 223, the process returns to the initial state (step 229) and the process is ended.

In the oven toaster according to the second embodiment, since the manual heating key 31 for forcibly heating (reheating) by manual operation is provided in the operating portion 9, the user can select the desired toast color. Can be fine-tuned.

In the second embodiment, the manual heating key 3 is used.

May be integrated to determine the re-energization time. For example, when the reheating time per operation of the manual heating key 31 is set to 10 seconds, if the manual heating key 31 is operated twice, re-energization is performed for 20 seconds, and if the operation is three times, 30 seconds and four times are operated. Then, it becomes possible to set it like 40 seconds. This improves the usability of the reheating operation in addition to the effects described above.

2, 3, 4, 5 is a block diagram showing the configuration of the control unit of the oven toaster, FIGS. 12 and 13 are flowcharts for explaining the operation of the control unit, and FIG. 14 is a flow chart for explaining the operation of the control unit. Is a timing chart for
In each drawing, the same reference numerals are given to portions corresponding to the above-described first embodiment.

In the oven toaster according to the third embodiment, when the pause timer 19 is stopped, the storage means 41 for storing the pause time ta accumulated so far is stored in the control device 16A.
And a heating time comparison means 42 for comparing whether or not the heating time t has continued for a predetermined time (here, set to 1 minute) or more, and when the heating time t is within the predetermined time (1 minute), The heating control means 23A adds the heating time tb at this time and the rest time ta stored in the storage means 41, and sets the added value tx = tb + ta as an initial value in the rest timer. . The other configurations are the same as those in the first embodiment.

Next, the operation of the oven toaster according to the third embodiment will be described based on FIGS. 12 to 14 with reference to FIG. The operations of step 311 to step 319 are the same as those of step 111 to step 1 of the first embodiment.
The operation is the same as that of Step 19, and the operations of Steps 325 to 327 are also Steps 124 to 34 of the first embodiment.
The operation is similar to that of step 126, and further, step 31
The transition operation from 3 to step 337 is also the same as in the first embodiment.
Since the operation is the same as the transition operation from step 113 to step 129 in step 129, the description of the operation of each step is omitted here, and the operation after step 320, that is, after the energization of the heaters 5 and 6 is started and after the correction is performed. Set heating time t
The operation after the start / stop key 13 is forcibly stopped before the elapse of 1 will be mainly described.

First, when energization of the heaters 5 and 6 is started (step 318) and the heating timer 24 is activated (step 319), the controller 16A forcibly stops energization of the heater by the start / stop key 13. It is determined whether or not it has been turned off (step 320), and it is turned off.
If not, the heating time t accumulated by the heating timer 24
Is the corrected heating time t set in step 317.
1 (step 321) and the comparison result is t ≧
If not t1, the process returns to step 320. Step 321
If the comparison result is t ≧ t1, the heating control means 23A
Stops energizing the heaters 5 and 6 (step 32
2) Activate the pause timer 19 (step 32)
3).

Next, the pause time tn accumulated by the pause timer 19 is compared with a preset upper limit pause time of 5 minutes (step 324). If the comparison result is not tn ≧ 5 minutes, start / stop It is determined whether or not the key 13 is turned on (step 325). If not, the process returns to step 324, and if it is on, the process returns to step 312.
That is, until the pause time tn exceeds 5 minutes, the integration of the pause time is continued while it is constantly determined whether or not the start / stop key 13 is turned on. If the comparison result is tn ≧ 5 minutes in step 324, the process returns to the initial state (step 326) and the process ends. The above is the first toast cooking (here, the set heating time t1 is 90 shown in FIG. 14).
It is assumed that it was seconds).

Next, a case where the second toast cooking is continuously performed within 5 minutes after completion of the first toast cooking (here, after 150 seconds shown in FIG. 14) will be described. First, in step 325 of the processing operation in the first toast cooking, the start / stop key 13 is turned on.
Is determined, and the process proceeds to step 312 while the integration of the downtime is continued, and the internal temperature T at this time is
h is measured. Then, in step 313, the internal temperature T
When it is determined that h is equal to or lower than the temperature T1 (150 ° C.), the process proceeds to step 314. Since it is determined in step 314 that the sleep timer 19 is operating, the process proceeds to step 327. In step 327, sleep timer 1
9 is stopped. Then, the rest time ta (1
50 seconds) is stored in the storage means 41 (step 328),
A correction value is selected and set based on the stored pause time ta (150 seconds) (step 329), and then the pause timer 19 is reset (step 3).
30) and moves the process to step 315.

In step 315, the reference heating time selecting means 26 uses the reference heating time table to determine the reference heating time T based on the inside temperature Th and the burned color density measured in step 312.
Select c. Then, in step 316, the rest time t
Reference heating time T based on the correction value according to a (150 seconds)
c is corrected, and in step 317, the actual heating time t1 that is the corrected reference heating time is set. Then, based on the set heating time t1, the heating control means 23A performs the second toast cooking under the same heating control as that in the first toast cooking.

Next, a case where the heater energization is forcibly stopped (OFF) by the start / stop key 13 during the second toast cooking will be described. First, in step 320 of the processing operation in the second toast cooking, it is determined that the heater energization has been forcibly stopped (OFF) by the start / stop key 13, and the process proceeds to step 331 where the heating is performed. The timer 24 is stopped. At the same time, the energization of the heaters 5 and 6 is forcibly stopped (step 332), and the heating time tb at this time (here, 30 seconds shown in FIG. 14) is measured (step 333). This measured heating time tb
(30 seconds) is compared with the preset 1 minute by the heating time comparison means 42 (step 334). If the comparison result is not tb ≧ 1 minute, the heating control means 23A adds the heating time tb (30 seconds) at this time and the rest time ta (150 seconds) stored in the storage means 41 (step 335). , This added value tx = tb + ta = 30 + 1
50 = 180 seconds is set as the initial value in the pause timer 19 (step 336), and the process proceeds to step 323. If it is determined that tb ≧ 1 minute in step 334, the heating time tb and the rest time ta are not added, and the process proceeds to step 323.

That is, when the heating time t is not continued for a predetermined time (for example, 1 minute) or more, the heating time t at this time is
b is added to the previous rest time ta, and processing is performed assuming that there is no heating. Further, the inside temperature Th increases due to the fact that the inside temperature Th is actually heated for 30 seconds, and this inside temperature Th is measured in step 312, and based on this, step 315
Since the reference heating time Tc is selected in, the influence of the increase in the internal temperature Th due to the actual heating can be avoided.

As described above, in the oven toaster according to the third embodiment, even if the automatic heating control is forcibly stopped during the toast cooking, the automatic control taking into account this is possible, When forcedly stopped, the control device does not erroneously determine that toast cooking has been officially performed, and the accuracy of heating control is improved.
