Description

electric range

The present invention relates to an electric range, and more particularly, to an electric range having improved management convenience and sanitary performance.

BACKGROUND ART In general, an electric range is a cooking appliance that heats a cooking container without using a flame using an induction or hot wire heater, and the demand is increasing due to safety of use and ease of handling.

On the other hand, the electric range is provided with a top plate formed of a heat-resistant material so that an object to be heated, such as a cooking vessel, is seated on the upper surface, and heating means such as a working coil is provided under the top plate.

And, the top plate is provided with a temperature sensor for measuring the temperature of the heating target, the heating means may be controlled according to the temperature measured through the temperature sensor. At this time, since the temperature sensor is installed so as to be in direct contact with the heating target through an opening formed in the center of the top plate for the precision of temperature measurement, foreign substances such as broth enter the cooker through a minute gap between the temperature sensor and the opening during cooking. can be introduced into

Accordingly, in the prior art, a water storage container for accommodating foreign substances is disposed below the temperature sensor so that foreign substances introduced between the temperature sensor and the opening do not flow toward the working coil and the control circuit, or a drain hole is formed at the bottom of the temperature sensor to prevent the introduced foreign substances from flowing into the cooker. It adopts a structure that discharges to the outside.

However, since the conventional water storage container requires a process of periodically separating it from the cooker in order to remove the accommodated foreign substances, there is a problem in that it is not suitable for application to a built-in method that is integrally buried in a sink or a table.

In addition, when the drain hole for inducing and discharging foreign substances introduced between the temperature sensor and the opening to the outside of the cooker is formed, there is a problem in that the foreign substances are directly discharged into the internal space of the sink or dining table where the cooker is embedded in a built-in manner.

For this reason, not only a cumbersome process such as separating the cooker to clean the internal space is required, but also hygienic problems such as bad odor or discoloration of the sink/table are caused when inadequate management is performed, thereby reducing product satisfaction.
