A lighting system for an electric fireplace, and a fireplace assembly including such system, may include a plurality of logs arranged in different orientations and in different rows. Some of the logs may include a substantially planar surface facing forwards. A front projector may project a lighting effect onto the logs, including the substantially planar surfaces, and a rear projector may project a lighting effect onto a non-transparent screen positioned behind the plurality of logs. The lighting system desirably provides a realistic three-dimensional flame effect in conjunction with a log set having a natural, split-log appearance. Other features may be included to enhance the lighting system, including internal lights in the logs and in an ember bed, as well as coloration of the logs to enhance the lighting effects and the natural appearance of the logs.

The present invention provides a gas valve and a control device and a control method thereof wherein the control device receives a detection voltage generated by a thermocouple. the control device outputs the second voltage when the detection voltage generated is greater than a predetermined voltage, and then outputs the first voltage. The control device stops outputting the first voltage when receiving a shut-off signal, and the control device starts counting time and stops outputting the second voltage when the time counted reaches a predetermined time.

An exhaust and air intake system for a direct vent fireplace. A low-profile manifold assembly is coupled to a direct vent fireplace and is configured to receive exhaust gases from the fireplace and expel the exhaust gases outside of the building in which the fireplace is located. The manifold assembly also takes in fresh air from outside of the building and provides the fresh air to the fireplace to use during combustion. The manifold assembly includes separate chambers for the exhaust gases and the fresh air so that the exhaust gases and the fresh air do not mix together within the manifold assembly. Several pressure reduction and equalization structures are incorporated into the manifold assembly to regulate the amount and pressure of fresh air provided to the fireplace.

A method utilizing an automated bending machine to bend Z-bar into a circular configuration for use as a fire pit ring or other structure. Z-bar has the desired cross-section such that when it is rolled into a circular configuration, it features a vertical intermediate section, an upper lip extending outward from said vertical intermediate section and lower lip extending inward from said vertical intermediate section. The upper lower serves to hold the fire pit ring in a support structure while the lower lip serves to hold a fire pit container.

A flow control apparatus includes a flow control signal generation device for generating a DC control signal based on an audio signal and at least one proportional valve. The flow control signal generation device includes an audio receiving module, a filter rectifier module, a microprocessor and a proportional valve control signal generation module. The filter rectifier module generates at least one DC audio signal by filtering the audio signal provided by the audio receiving module. The microprocessor generates a plurality of period attenuated values based on the DC audio signal. The proportional valve control signal generation module filters the audio signal, attenuates the signal based on the period attenuated values, and then performs filtering and rectification processing to generate the DC control signal, such that the proportional valve may control the opening ratio of the proportional valve based on the DC control signal.

The present invention discloses a flame simulating device, comprising a mist generating chamber, an atomizing head, an air orifice and a nozzle. The inside of the mist generating chamber is provided with a liquid and the atomizing head, the atomizing head being capable of atomizing the liquid inside the mist generating chamber, the two sides of the nozzle being set as Coanda curved surfaces, the cross section of the air orifice being in a constricted shape and providing an air flow blown upward such that under the Venturi effect, the air flow blown upward will guide and attract the mist from inside the mist generating chamber to vent out and flow into a nozzle inlet. Due to the Coanda curved surface on the side of the nozzle, the mist flows along both sides of the nozzle under the Coanda effect and then vents out of the nozzle.

An apparatus and method for aesthetic enhancement of indoor and outdoor living spaces combines fire, bubbling water and light reflection to foster enjoyment and relaxation. Wall assemblies having glass panes are spaced apart from each other to provide a chamber to hold water separate from a burner assembly. Air pumped into the water forms air bubbles in the water. A LED light strip illuminates the water, bubbles and glass panes in changing colors.

The present invention discloses a regulating mechanism regulating the flows from a plurality of gas outlets in a fuel gas valve, comprising an actuator, a push rod, a presser plate assembly, regulating rods and a valve body. Wherein the valve body has a plurality of gas outlets, a regulating rod is provided in each regulating port which exists between the gas inlet and each gas outlet, a resetting device is provided between each regulating rod and the valve body, and the actuator drives the push rod which is around by the regulating ports to move along the axis. The push rod causes the presser plate assembly to move up and down to press or relax the regulating rods and simultaneously change the degree of opening between the head portion of each regulating rod and the corresponding regulating port so that the flow from each gas outlet changes synchronously.
