Description

Control method of thawing by weight of microwave oven

The present invention relates to a method for controlling the thawing by weight of a microwave oven, and more particularly, by setting the thawing time according to the weight of the sea animal in different stages and by setting a rest period, the thawing by weight of the microwave oven is performed. It relates to a control method.

In general, a microwave oven is an electronic device that cooks food by using a high frequency oscillated from a magnetron, and has a thawing function, a warming function, and a cooking function by a multi-stage output of the magnetron.

In addition to the magnetron, there is a grill cooking function using a heater and a combination function using a heater and a magnetron at the same time, and an oven function of circulating hot air inside the cooking chamber with a convection heater and a convection pan installed at the rear of the cooking chamber.

In such a microwave oven, a cooking method is a sensor type automatic cooking control method that detects humidity generated from a food product by heating using a humidity sensor and automatically controls cooking time, and cooking amount according to cooking name and serving. There is a program type automatic cooking control method that finds the cooking time set by experiment in advance and controls the heating during the cooking time by manually inputting.

In order to cook in a microwave oven, put the food into the cooking room with the power connected, close the door, select the output level, select the cooking function, press the start key, and the magnetron will start under the control of the microcomputer. To cook.

These microwave ovens are diversified in their functions, and are being developed day by day to get closer to the user's preference.

In such a general microwave oven, the conventional thawing control method divides the thawing time set by the thawing button into five stages.

Here, the first stage is 20% of the total thawing time, the second stage is 10% of the total thawing time, the third stage is 10% of the total thawing time, the fourth stage is 20% of the total thawing time, and the fifth stage is the total thawing time. 40% of the time.

At this time, look at the output level of the magnetron for each stage, the strong level (level 9) in the first stage, the weak level (level 2) in the second stage, the magnetron off state in the third stage, the weak level in the fourth stage (level 2 In step 5, the level becomes medium and weak level (level 3).

When the thawing time is set unconditionally regardless of the weight of the sea animal, the thawing time is divided into five stages as described above.

Therefore, in the conventional thawing control method as described above, the thawing time set irrespective of the weight of the sea animal is divided into five stages as described above, and the output level of the magnetron is undivided into five stages set unconditionally. There was a problem in that the thawing effect was lowered because the resting time, which was the standing time, was short.

In addition, even after thawing by step 5, the thawing is often not possible, so that the user's natural neglect time is long.

Accordingly, an object of the present invention is to solve the conventional problems, and provides a thawing control method for each microwave in order to achieve the optimum thawing by setting different thawing times according to the weight of the sea animals and also setting a rest period differently. Is in.

The object of the present invention is to measure the weight of the sea animal when the thawing function is selected by the user; Setting the thawing time of the first stage or the resting stage of the third stage according to the measured weight of the sea animal in the state where the thawing time is divided into four stages; and setting the output level of the magnetron in the fourth stage after the thawing time is set. And thawing the animal according to the set thawing time and the output level of the magnetron.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic configuration diagram of a microwave oven to which the present invention is applied.

As shown in the drawing, the M / W key 10 for setting a manual function or changing an output level during operation, and a key input unit including a plurality of keys for selecting a function and setting a time such as thawing and automatic cooking ( 20), the weight measuring unit 70 for measuring the weight of the marine animal on the turntable, and the overall operation of the microwave control in accordance with the function set by the M / W key 10 and the key input unit 20 And, when thawing, the microcomputer 30 for controlling the thawing by drawing a thawing program stored in the memory 60 according to the weight of the sea animal obtained by the weight measuring unit 70, and the oscillation under the control of the microcomputer 30 A magnetron 40 for generating electromagnetic waves (microwaves) for cooking and thawing, a display unit 50 for displaying an output level and cooking time of the magnetron 40 under the control of the microcomputer 30, and Defrost by weight for thawing Was composed of a memory 60, a program is built.

Figure 2 is a control flow chart showing a thaw control method of the microwave oven according to the present invention.

As shown therein, a step (S1) of searching whether the thaw is selected, a step (S2) of measuring the weight of the sea animal, a step of setting the thawing time according to the weight of the sea animal (S3), and a magnetron The step of setting the strength of the in four steps (S4), the thawing proceeds according to the set thaw time and the strength of the magnetron (S5).

Referring to the microwave oven to which the present invention having such a configuration is applied, the thawing control method according to the preferred embodiment of the present invention will be described in detail as follows.

First, when the user places the animal on the turntable in the cavity to thaw the animal, closes the door and selects the thawing function through the key input unit 20, the microcomputer 30 recognizes this and weighs ( Read the weight of the sea animal measured in 70) (S1) (S2).

After that, the thawing program is drawn out from the memory 60 according to the weight of the sea animal, and the thawing is performed by controlling the output level of the magnetron 40 accordingly (S3-S5).

Here, the thawing program divides the total thawing time into four stages, and divides the total thawing time into four stages in such a way that the first stage thawing time increases as the weight of the sea animal increases.

In addition, by setting the resting time variably according to the weight of the sea animal, the deterioration effect of the thawing effect caused by the short resting time, which is a thawing period in the natural state as in the past, is prevented.

On the other hand, the intensity of the magnetron is set to four stages, such as the middle stage 1, the middle stage 2, the middle stage 3, the off stage idle, the fourth stage weak.

Thereafter, thawing is performed according to the strength of the magnetron according to the set thawing time to thaw the animal.

Table 1-1 below is an example of the thawing time for each weight included in the memory 60.

Table (1-1) Thawing Time by Weight

Weight (Kg) Thawing time Stepwise time allocation and magnetron strength Stage 1 Tier 2 Tier 3 4 steps Medium, river level Middle level Off About level 0.1 7 minutes 31 seconds 4.5% 4.5% 91.0% - 0.5 15 minutes 55 seconds 10.5% 10.5% 60.0% 19.0% 1.0 26 minutes 30 seconds 12.5% 12.5% 49.0% 26.0% 1.5 37 minutes 05 seconds 13.5% 13.5% 44.0% 29.0% 2.0 47 minutes 40 seconds 14.0% 14.0% 41.5% 30.5% 2.5 58 minutes 15 seconds 14.5% 14.5% 40.0% 31.0% 3.0 68 minutes 50 seconds 14.5% 14.5% 39.0% 32.0% 3.5 79 minutes 25 seconds 14.5% 14.5% 38.0% 33.0% 4.0 90 minutes 00 seconds 15.0% 15.0% 37.0% 33.0%

Looking at the above table (1-1), the first stage of thawing is a step of melting the surface of the animal slightly, and it can be seen that the weight increases gradually, and the rest period is considerably longer than the existing one, thus eliminating the problem of ripening of the animal. It can be seen that it is implemented to reduce the thawing deviation.

As described above, according to the present invention, the distribution of the thawing time is set differently according to the weight of the sea animal, and when the thawing time is set, the higher the weight, the more the first thawing time is increased, and the resting time is variably set so that the optimum thawing is achieved. There is a possible effect.
