Abstract

PURPOSE:To prevent a space heater from abnormally heating at its body due to quick room heating by detecting the temperature of the body, and using it as one of conditions for determining its height whether a quick space heating should be executed or not. CONSTITUTION:When an operation switch 26 is closed, a signal is fed to a discriminator 27, a combustion controller 28 operates an ignitor 34, a solenoid valve 35, and starts burning by a burner 37. A fan motor controller 29 operates a fan motor driver 21, and drives a blowing fan 20. A quick space heat discriminator 30 discriminates whether a space temperature is a set value or less by a space temperature detector 32 and whether the temperature of a space heater body is a set value or less by a body temperature detector 33, outputs a signal for executing a quick space heating if both are less and a signal for not executing the quick space heating if is not. A quick space heat controller 31 receives it to control a combustion amount regulator 36 to increase or set to a normal combustion amount.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a rapid heating control device for combustion equipment in various fields, mainly for heaters that burn gas or oil as fuel.

Conventional technology In recent years, one of the additional functions of heating appliances has been to rapidly increase the combustion amount by a certain amount beyond the maximum combustion amount during normal operation for a certain period of time from the start of operation or until the room temperature reaches a certain condition. A so-called rapid heating system has been added to improve comfort by providing immediate warmth when the room temperature is low and preventing the feeling of cold air. However, since combustion is performed at a combustion rate greater than the maximum combustion rate, it is important to prevent a decrease in safety due to abnormal heating of the vessel body.

An example of the above-mentioned conventional rapid heating control device for a heating appliance will be described below with reference to the drawings.

A smoothing capacitor 6 smoothes the DC power obtained by the rectifier 5. 7 is resistance. Reference numeral 8 denotes an operation switch, which turns the appliance on and off. Reference numeral 9 denotes a determination section, which determines and controls the operation of the appliance based on the signal from the operation switch 8. Reference numeral 10 denotes a combustion control section, which performs combustion control based on a signal from the operation switch 8. Reference numeral 11 denotes a fan motor control section, which outputs a control signal to the fan motor drive section 3. Reference numeral 12 denotes a rapid heating determination unit, which determines whether or not rapid heating is to be performed. 13
is a rapid heating control section, which performs rapid heating control based on a signal from the rapid heating determination section 12. The determination unit 9 includes a combustion control unit 10, a fan motor control unit 11, and a rapid heating determination unit 12.
, and a rapid heating control section 13. 14 is a room temperature detection section that detects the room temperature and sends it as a voltage signal to the rapid heating determination section 12. 15 is an igniter.

Reference numeral 17 denotes a combustion amount adjustment section, which increases the combustion amount in response to a signal from the rapid heating control section 13. A burner 18 performs combustion.

The operation of the rapid heating control device for a heating appliance configured as described above will be described below with reference to the drawings.

First, commercial power obtained through the outlet 1 is stepped down by the transformer 4, full-wave rectified by the rectifier 5, and then smoothed by the smoothing capacitor 6 to become direct current. The control described later is performed using the DC power source obtained by the above method. When the electrical switch 8 is turned on, a signal is sent to the combustion control section 10, fan motor control section 11, and rapid heating determination section 13.
The combustion control unit 10 operates the igniter 15 and the electromagnetic valve 16 to start combustion by the burner 18 . Further, the fan motor control section 11 operates the fan motor drive section 3 to drive the ventilation fan 2. Based on the signal from the room temperature detection section 14, the rapid heating determination section 12 outputs a signal to perform rapid heating if the room temperature is below a set value, and outputs a signal not to perform rapid heating if the room temperature is above the set value. Rapid heating control section 13
controls the combustion amount adjustment section 17 based on the signal from the rapid heating determination section 12, and increases the combustion amount or adjusts it to the normal combustion amount. Rapid heating is terminated when the operation switch 8 is turned off or when the room temperature rises and the signal sent to the rapid heating determination section 12 via the room temperature detection section 14 exceeds a set value. In this way, whether or not to perform rapid heating is determined only by the room temperature when the operation switch 8 is turned on, regardless of the degree of comfort, such as immediate warming or preventing the feeling of cold air when the room temperature is low.
