Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a combustion hot air heater that performs heating by dissipating high-temperature combustion gas into a room.
[0002]
[Prior art]
Combustion hot air heaters, such as fan heaters, that dissipate combustion gas in the room to heat the unit can reliably avoid the occurrence of various dangers due to incomplete combustion, etc., when combustion continues without ventilation. As described above, the combustion is surely stopped (fire extinguished) when a predetermined time (for example, 3 hours) elapses from the start of the combustion.
[0003]
In that case, after the remaining time until the combustion stop becomes, for example, 30 minutes, the remaining time decreasing is displayed on the display device, and the state where the heater is placed can be directly recognized by the warmer. It was like that.
[0004]
In addition, after the remaining time is displayed, for example, when operating a temperature adjustment operation switch, the remaining time value displayed on the display device can be switched to the current room temperature display. As a result, it was possible for the warmer to know the heating information other than the remaining time.
[0005]
[Problems to be solved by the invention]
In the above-described conventional example, the remaining time is not displayed unless a predetermined time has elapsed after the start of the combustion operation. Therefore, within a period in which the remaining time display is not performed, such as immediately after the start of the combustion operation, Except when the time when the operation start / stop switch was operated was clearly stored by the warmer, it was difficult to accurately grasp the remaining time.
[0006]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention provides an operation start / stop switch operated to start or stop combustion operation, a heating temperature setting switch operated to set a heating target temperature, and a heating space Display content selection switch operated to select and display one of current room temperature or remaining operating time, temperature sensor for detecting the air temperature in the heating space, and for generating a time signal A timing device, a display device that selectively displays one of the current room temperature and the remaining operable time of the heating space during the combustion operation according to the operation of the display content selection switch, and When the stop switch is operated to start the combustion operation, the heating target temperature set by the heating temperature setting switch and the heating space detected by the temperature sensor are detected. The time signal generated by the time measuring device is taken in accordance with the degree, and the combustion operation for a predetermined time is executed, and the first first fixed time range in the combustion operation for the predetermined time When the display content selection switch is operated while displaying the current room temperature on the display device, the display content is switched to display the remaining operable time, and vice versa for the remaining second fixed time range. When the display content selection switch is operated while displaying the remaining operation time on the display device, the combustion hot air heater is configured with a control circuit that switches the display content to the current room temperature display.

【Example】
An embodiment of the present invention will be described below with reference to FIG.
[0010]
In FIG. 1, reference numeral 1 denotes an operation start / stop switch which is provided at an appropriate place (operation panel or the like) of a hot air heater (not shown) and is operated to instruct the start and stop of operation. Similarly, the heating temperature setting switch 3 operated to set the target air temperature of the heating space is operated to display either the current room temperature or the remaining operable time of the space during heating on the display device described later. This is a display content selection switch.
[0011]
4 is a temperature sensor for detecting the air temperature of the space to be heated, 5 is a time measuring device for generating time information, and 6 is selectively instructed to either the current room temperature during combustion operation or the remaining operable time. A display device for displaying.
[0012]
And 7 takes in the signal of the operation start / stop switch 1, the signal of the heating temperature setting switch 2, the signal of the display content selection switch 3, the signal of the temperature sensor 4, and the signal of the time measuring device 5, and the combustion of the warm air heater When the operation is started or stopped, the combustion operation is controlled based on the target air temperature of the space to be heated, and the current temperature detected by the temperature sensor 4 is displayed on the display device 6 while this state continues. In the meantime, when the current temperature reaches the value set by the heating temperature setting switch 2, control such as changing the combustion amount is executed, and when a predetermined time has elapsed in the flow, This is a control circuit that displays the current room temperature displayed on the display device 6 by switching to the remaining operating time. Moreover, the control circuit 7 not only displays the current room temperature detected by the temperature sensor 4 on the display device 6 within the first first predetermined time before the predetermined time elapses after the combustion operation is started. In the meantime, when the display content selection switch 3 is operated, the display device 6 is also provided with a function of switching the display of the current room temperature to the remaining operating time only during the operation.
