Problems solved by technology

Then, contrary to the user's intention, it is determined that a plurality of touch keys are input and operated at the same time, and the operation intended by the user may not be performed.
For example, touch keys are often installed on a flat surface, and it is difficult to visually determine the area where input detection can be performed.

Abstract

The invention relates to a refrigerator, which aims at preventing error detection of an operation part in the refrigerator provided with an electrostatic capacitance type touch switch operation part. The refrigerator in the invention is characterized by comprising: a storage chamber disposed at the refrigerator main body; a storage chamber door opening and closing an opening at the front part of the storage chamber; an operation part disposed in the front of the storage chamber door in a plane shape; an electrostatic capacitance type touch switch electrode disposed in a contact with or close to the rear part of the operation part; a contact sensor element detecting change of the electrostatic capacitance of the switch electrode; and wiring connected with the switch electrode and the contact sensor element, the wiring is disposed in a way of preventing a projection position of fingers during operation of the switch electrode.

Description

technical field [0001] The present invention relates to refrigerators. Background technique [0002] As a conventional refrigerator, it is known to equip an operation part (such as a button, etc.) on the front of the door. By operating the operation part, various functions such as adjustment of the storage room temperature, rapid freezing, rapid refrigeration, and automatic ice making device are operated. Structure. In addition, mechanical switches such as microswitches are known as the above-mentioned operation unit. [0003] Furthermore, in recent home electric appliances in particular, structures using capacitive touch sensors are known. As an example of a home electric appliance equipped with a touch sensor, there is Japanese Unexamined Patent Application Publication No. 2005-251504 (Patent Document 1). [0004] In Patent Document 1, the following structure is described, comprising: a cooker main body; a top plate mounted on the cooker main body; a heat source arrange...
