Gas fireplace with gas controlling device and method of controlling gas consumption of the gas fireplace

摘要

A gas fireplace includes a gas valve, a combustor, and a gas controlling device between the gas valve and the combustor. The gas controlling device has a body, a solenoid valve, and a main controller. The body has a first port, a second port, a first passage, and a second passage, wherein the first passage and the second passage respectively connect the first port to the second port. The solenoid valve is provided in the first passage to be controlled to open and close the first passage. The main controller alternately turns the solenoid valve on and off so as to repeatedly open and close the first passage. Therefore, the gas controlling device provides a variable gas flow to the combustor to reduce the total gas consumption and the user will not be aware of the change of the flames.

1. A method of controlling a gas consumption of a gas fireplace which has a gas controlling device having a body and a solenoid valve, wherein the body has a first port through which gas enters the body, a second port through which gas leaves the body, a first passage connecting the first port and the second port with the solenoid valve provided within to be opened or closed, and a second passage also connecting the first port and the second port, comprising the steps of:
A. providing a first gas flow to a combustor for a first time while the solenoid valve opens the first passage; B. providing a second gas flow to the combustor for a second time while the solenoid valve closes the first passage; and C. repeating the step A and the step B until the gas fireplace is turned off.
