Description

[Detailed description of the invention] This invention relates to an improvement in a heating cooker.

Generally, food is cooked using a heating cooker, and the heating time is currently set using a manual timer based on the user's intuition and experience as well as cooking books, etc.; however, this heating time depends on the amount of food. It is necessary to change the temperature, and it also changes depending on the item being cooked, making it very difficult to set the time and making it difficult to heat the food to the optimal temperature. Although there was a need to calculate the calories in Maku food products, it was not technically possible.

This invention was made by focusing on the points mentioned above, and is capable of cooking by measuring the weight of food, calculating and displaying the calories of the food, and automatically setting the heating temperature according to the measured weight. The purpose is to provide equipment.

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

Figures 1 and 2 show an embodiment of the present invention, and in the figures, l is a heating chamber provided in the cooking device main body 2 (hereinafter referred to as the main body), and 3 is a heating chamber provided on the bottom surface of the heating chamber l.

is based on the weight information of the weight detecting section 12 at the time when the above-mentioned start signal is received, that is, the initial weight information of the food, and the weight information of the weight detecting section 12 at the time when the counting section 13 outputs the pulse signal. Accordingly, the amount of weight loss of the food after a predetermined period of time has elapsed from the start of cooking is calculated, and together with the counting section 13, a polydispersion amount calculation section 15 is constituted. Reference numeral 16 denotes a total heating time calculating section, which calculates the net weight of the food from the amount of weight loss calculated by the weight change amount calculation section 15 (using a calculation formula preset based on the cooking item information).

The total heating time from the start of cooking is calculated accordingly. 17 is a heating time setting section for the remaining heating time, which calculates the heating time for the remaining heating time from the total heating time calculated by the total heating time calculation section 16 and the count time at this point of the counting section 13; (Remaining) This control unit controls the operation of the heating device 6 after the heating time has elapsed, and constitutes a heating control unit 18 together with the total heating time calculation unit 16. 19 is a display section, and the main body, .

The calories of the food are calculated based on the information from the weight detection section 12, and the calculated value is displayed on the display section 19.

The operation of the heating cooker configured as described above when actually heating food will be described.

For example, when making a cake, pour the ingredients into a cake mold (not shown), place it on the mounting table 3 in the heating chamber l, and place the item to be cooked (in this case a cake) with a key. If you first press the calorie calculation instruction key 5m after entering the input using the corresponding key in the key 5, the signal detected by the weight detection unit 12 will be input to the calorie calculation unit 20], and the preset calculation formula for each of the nine items will be input. is calculated based on and displayed on the display unit 20. If there is no need to calculate calories, the cooking start key 11 is pressed immediately, and as a result, the cooking start signal output section 1O outputs a start signal, and the heating device selection section 9 selects the heating device 6 according to the sponge cake. The heater heating device 8 is selected as follows. Then, the heater heating device 8 is operated in response to the start signal, and heating cooking is started. In addition, the counting section 13ti of the weight change amount calculating section 15
Upon receiving the start signal, the percentage calculation section 14 counts the time after that, and the percentage calculation section 14 also calculates the weight information (i.e., the container weight W and the weight of the sponge cake material) from the weight detection section 12 at the time when the counting section 13 received the start signal. The weight w, which is the sum of the initial net weight W1 is read. Predetermined time T

The calculation unit 14 of No. 5 again calculates the weight information (
That is, the weight W4) which is the sum of the capacity weight W0 and the current net weight W1 of the sponge cake material is read.

In general, when a food is heated, water evaporates and its weight decreases, which is 1+, and the amount of weight loss increases as the amount of food increases, so the relationship Ws < Ws), weight loss w= It is expressed as Wt-W4=W@-Wt. Therefore, the calculation unit 14 calculates this weight reduction amount W. Next, the total heating time calculation section 1 of the heating control section 18
6 is a calculation formula prepared in advance to calculate the initial net weight of the food from the value of the weight loss il'w, for example, W1.
= v・α0C (where α is a constant and C is a constant that changes depending on the cooking item) K], calculate the net weight W1 of this food, and calculate the value of the net weight W1 according to the value of this net weight W1. Set the total heating time t1. Here, the remaining heating time setting section 17 of the heating control section 18 calculates the remaining heating time t by 1.0 from the total heating time tl and the current count time 1t (tt 1,000 T) of the counting section 13. = 1. -1. The remaining heating time t is calculated and displayed on the display section 19 while counting down. When the remaining heating time t is suitable, the operation of the heater heating device 8 is stopped by the operation of the remaining heating time setting section 17, and the cooking is completed.

As explained above, this invention measures the weight of food,
The calories of this food can be calculated and displayed, and the heating time can be set and cooked automatically according to the measured weight of the food, making it convenient for health management. It has a great practical effect in that it can be done properly.
