Weighing device having a weighing chamber

摘要

A weighing device is provided that suppresses air convection currents generated in a weighing chamber in the opening/closing of a door of the chamber with a relatively simple configuration. A weighing space is partitioned into two spaces with a partition plate to form a lower small-capacity weighing chamber, which enables to settle down the convection in a short time if convection is generated in the chamber. Suspended walls adjacent to the doors are attached to the partition plate edge sides along the door opening/closing directions. Even when a door is opened, warm air stagnant in the upper space in the chamber is restricted or blocked to flow out to the outside by the suspended walls, which generates no convection or slight convection, which settles down in a short time, without adverse effect on a weighing operation. The upper space may be utilized for another purpose such as a neutralization chamber.

主权项

1. An electronic scale comprising
a weighing space, which is openable and closable, in which a weighing dish is internally disposed, the electronic scale having a weighing chamber wherein the entire weighing space is configured as a weighing chamber, and a pair of suspended walls which are at an upper part of the weighing chamber, both of which are adjacent to a door of the weighing chamber, and have given widths vertically, are disposed along opening and closing directions of the adjacent door, wherein the weighing space is partitioned into upper and lower spaces with a partition plate, the lower space is configured as a weighing chamber, and the suspended walls are fixedly hung on the lower space side along side edges of the partition plate.
