PURPOSE:To provide a device which measures weight of food with a high accuracy and also has good cooking performance without a large space in the vertical line to the bottom of a cooker by installing a primary elastic body for weighing light weight food only and secondary one exclusive for heavy weight food. CONSTITUTION:The relation between food weight W and distance (d) between two plates 12a, 12b of a condenser is shown in a figure. In case of weighing light weight food stuff, the primary elastic body 19 is only operated with characteristic as shown by dotted line and in case of weighing beyond heavy weight W1, the primary elastic body is supported by the secondary one and as a result, two elastic bodies 19, 16 are operated simultaneously and weight resolving power becomes poor. The heavier the food stuff weight becomes, the larger the allowable error becomes linearly and therefore, it is sufficient to measure the rough weight in the range beyond weight W1. For poor accuracy, there is no problem on cooking performance and therefore, the same performance is expected with former accuracy. |
