FIG. 6 is an explanatory view showing a conventional display panel. In the drawing, reference numeral 105 denotes a display device in which seven segments provided on the display panel 102 are arranged in a substantially figure-eight shape, and is a set temperature, an ambient temperature such as a room temperature, a current time, or a time such as an ignition timer. Used for display.
Reference numeral 106 denotes a combustion amount display unit, and a weak combustion amount display lamp 106.
a, a medium combustion amount display lamp 106b, and a strong combustion amount display lamp 106c.

FIG. 7 is an explanatory diagram showing an example of the operation of a conventional combustion amount display section. For example, the maximum calorific value of 3000 kca
In the case of a 1 / h heater, the combustion amount state "strong"
2010 kcal / h, combustion amount state "medium"
1010kcal / h, combustion amount state "weak" 1000k
If the current combustion amount is within the range of the combustion amount state “strong”, the state becomes “a”, the strong combustion amount display “H”, and the weak combustion amount display of the combustion amount display section 106. The lamp 106a, the medium combustion amount display lamp 106b, and the strong combustion amount display lamp 106c all light up. If it is within the range of the combustion amount state "medium", the state (a) becomes the medium combustion amount display "M" state, and the weak combustion amount display lamp 106a and the medium combustion amount display lamp 106b of the combustion amount display unit 106 Light. Similarly, when it is within the range of the combustion amount state "weak", (c) the weak combustion amount display "L" state is reached, and only the weak combustion amount lamp 106a of the combustion amount display unit 106 is turned on.

FIG. 8 is a timing chart showing the operation of a combustion amount display device in a conventional heater. In the figure, before the start of combustion, all the combustion amount display units 106 are turned off. Once the combustion is started, the combustion amount display unit 106 displays the combustion amount state according to the operation shown in FIG. Generally, at the start of combustion, the indoor temperature is lower than the set temperature, so the combustion amount state becomes "strong", and as the indoor temperature approaches the set temperature, the combustion amount state becomes "medium" and the combustion amount state becomes "weak". And migrate. Therefore, the combustion amount display state shifts from “H” to “M” to “L” as shown in the figure.

[0006]

The conventional combustion amount display device for a heater is constructed as described above. However, recently, this type of combustion heater has a medium combustion amount due to a problem such as improvement of ignitability. Since many control methods for ignition have been used, the amount of heat generated at the time of ignition falls within the range of the combustion amount state “medium”. Therefore, the combustion amount display unit 106 displays the medium combustion amount display “M” for a while after ignition.
Thereafter, the display changes to the strong combustion amount display “H” with the transition of the combustion amount. However, in general, a user who uses a heater considers that when the indoor temperature is lower than the set temperature, the heater operates at the maximum combustion amount at the start of heating. For this reason, a difference occurs between the operation of displaying the combustion amount of the heater and the recognition of the user, and this difference gives the user distrust.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and has a heater capable of displaying the amount of combustion without giving a user distrust while satisfying the improvement of ignitability. The purpose of the present invention is to obtain a combustion amount display device.
