Abstract

PURPOSE:To allow a control for a pleasant environment and improve the energy saving effect by performing a comparison between the timer and set temperature attaining time and designating one whichever comes first as the preheating operation time. CONSTITUTION:Upon setting a preheating timer 8, an operation command means 12 starts a fan 2 and a burner 3 based on the preheating command. The preheating operation time is monitored by a comparison and determining means 11, and, if the time T2 in which the difference between the set value by a temperature setting means 10 and the input signal from a room temperature input means 9 which is fed with a value detected by a temperature sensor 6 becomes smaller than a limit value W is earlier than the time T1 set by the timer means 8, or if the time T1 set by the timer means 8 comes earlier than the time T2 in which the difference between the value set by the temperature setting means 10 and the input signal from the room temperature setting means 9, the preheating operation is immediately terminated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application] The present invention relates to a control device for a heater used for heating a room.

[Conventional technology]

In recent years, hot air heaters have rapidly developed, and when used to heat a room, they can also perform preheating operation so that the temperature is equal to a predetermined set temperature.

When performing preheating operation with the above-mentioned conventional warm air heater, the startup time is generally set using a morning timer, program timer, etc.
This is a method of operating a warm air heater in advance to create a comfortable environment before HI.

Since the time required varies depending on the environmental conditions of the building, the user takes these conditions into account, estimates the required time empirically, and determines the start time of the warm air heater.

[The rain point that the invention attempts to solve] However,
With conventional methods, the heating continues within the set time even if various conditions change, so depending on the startup time, the heating state when the room is first used may be higher or lower than the desired temperature. There were problems in that it was difficult to create a comfortable environment and went against energy conservation.

This invention was made in order to solve the above-mentioned problems, and aims to provide a control device for a heater that can provide a comfortable heating condition at the beginning of use and can save energy. .

[Means for solving problems]

The heating machine control device according to the present invention includes a timer means, an indoor temperature input means, a temperature setting means, and a comparison judgment means, and the comparison judgment means is configured to compare the set time of the timer means and the indoor temperature input means, and a comparison judgment means. The system is configured to compare the time required for the difference between the input signal from the temperature input means and the set value of the temperature setting means to reach within a certain value, and output the earlier of the two as the end of the preheating operation time. It is something.

[Effect]

With the above configuration of the present invention, the timer means preheats the room before starting to use it, inputs the tufted layer state (IIN) from the indoor temperature input means, and uses this input signal and the value set by the humidity setting means. The comparison and determination means terminates the preheating operation e when the difference between the two values reaches a constant value, and the timer means also terminates the preheating operation when the set time elapses.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings.

In Fig. 1, inside the hot air heater housing 1, there is a blower 2.
, a combustor 3 is installed, and a hot air outlet 4 is provided in the front of the housing 1.
is provided, and on the back side there is an air intake port 5 that is sucked by the blower 2, and a temperature sensor 6 that detects the indoor temperature.
are provided for each.

F is a preheating operation control section, which includes a timer means 8 for determining the preheating operation time, an indoor temperature input means 9 for inputting the signal from the temperature sensor 6 as the indoor temperature, a temperature setting means 10 for setting the desired temperature, and the timer means. 8, an indoor temperature input means 9, and a temperature setting means 10.

Second about the WIJm device of the heater with the above configuration
This will be explained using the diagram and the time chart in FIG.

When the preheating timer means 8 is arbitrarily set, the operation command means 12 operates the blower 2 and the combustor 3 based on the preheating command. The preheating operation time is monitored by the comparison/judgment means 11, and as shown in FIG. When the time T at which the difference between the input signal of the indoor temperature input means 9 detected by the temperature sensor 6 installed on the back side and the input signal of the indoor temperature input means 9 reaches within a certain value W is earlier, or when the time T shown in FIG. As shown in FIG.
When r1 is reached earlier, the preheating operation is immediately terminated.

〔Effect of the invention〕

As described above, according to the present invention, by comparing the timer and the time to reach the temperature setting and setting the earlier of the two as the preheating operation time, it is possible to control a comfortable environment and improve the energy saving effect. It has the effect of being able to
