Description
【発明の詳細な説明】 （産業上の利用分野） 本発明は給湯器等の湯温表示方法に関する。[Detailed description of the invention] (Industrial application field) The present invention relates to a method for displaying the temperature of hot water in water heaters, etc.
（従来の技術）

フ状に表示したものがある。(Prior Art) Conventionally, water heaters and the like have been used to display the set temperature by lighting, and an example of such a display device is to use a plurality of light emitting diodes as proposed by the applicant in Utility Model Application No. 58-29572. There is one in which a number of light emitting diodes are arranged in a line and lit according to the set temperature, and displayed in a bar graph form.
（発明が解決しようとする問題点）
しかしながら、かかる表示装置では設定温度を
表示できても実際の使用温度が設定温度と一致し
ているかどうか不明であり、特に使用開始時には
湯温が設定温度に立上がるまで一定時間要するこ

表示装置を提供できることが考えられる。(Problem to be solved by the invention) However, even if such a display device can display the set temperature, it is unclear whether the actual operating temperature matches the set temperature, and especially at the beginning of use, the water temperature does not reach the set temperature. It takes a certain amount of time for the product to start up, so if the startup time is long, the hot water temperature must be set higher, or if it overshoots, the water temperature must be set lower, leading to incorrect operation and creating a poor usability. Therefore, if the set temperature and the detected hot water temperature are both displayed on the display device, it is possible to provide a display device that is easy to use.

されている。 By the way, conventionally, a configuration for displaying a plurality of different contents on a common display means is disclosed in, for example, Japanese Patent Laid-Open No.
It is known from Public Relations No. 141947. In this known example, different contents are displayed by changing the illuminance of a single lamp, which is a difficult configuration for temperature display.In addition, in other conventional examples, there is a difference between continuous lighting and blinking of the light emitting diode. A configuration for displaying content has already been adopted.

を生じる。 However, as mentioned above, in order to display the set temperature or hot water temperature in a bar shape by arranging multiple light emitting diodes in a row, the conventional technology requires that the number of display output terminals of a microcomputer in the display control section be adjusted to emit light. It is necessary to provide the same number of diodes,
It is expensive, and there are problems such as an insufficient number of output terminals to perform other displays using the output terminals.
