Abstract:
A method of controlling a remote controlled system includes the steps of: A. establishing corresponding relationships between a detector and home appliances; B. measuring a specific physical quantity with the detector; C. determining if the measured physical quantity is abnormal; and D. controlling the corresponding home appliances to perform certain operations according to the corresponding relationships if the measured physical quantity is abnormal, whereby, the physical quantity measured by a common detector can be feedbacked to multiple home appliances, which effectively reduces the number of the required detectors.
Abstract:
A plug member of a gas valve includes a main body. The main body has an axial bore in an axial direction, a first inlet and a second inlet in radial directions, and a guiding slot on a surface. The first inlet and the second inlet are connected to the axial bore. A diameter of the first inlet is greater than a diameter of the second inlet. The guiding slot has a first end communicated with the first inlet and a second end communicated with the second inlet, and a width of the guiding slot gradually reduces from the first end to the second end. Therefore, the gas valve may provide a gas flow with a linear change by controlling the plug member.
Abstract:
A method of controlling a temperature in a room includes the following steps: 1) Sense a volume of sound in the room to obtain a sensed volume; and 2) Control an output of an air conditioning unit to keep a temperature in the room in a first temperature while the sensed volume is higher than a volume value; or control an output of the air conditioning unit to keep a temperature in the room in a second temperature while the sensed volume is lower than the volume value and lasts for a first waiting time. A power consumption of the air conditioning unit to keep the temperature in the second temperature is lower than a power consumption of the air conditioning unit to keep the temperature in the first temperature to reduce the unnecessary power consumption when there is nobody in the room.
Abstract:
A temperature-controllable gas grill includes a base, a cover, a gas valve, several burners, and a temperature controlling device. The cover is provided on the base to form a grilling chamber between the base and the cover. The gas valve is connected to the gas pipe. The burners are provided in the base and are connected to the gas valve. The temperature controlling device includes a gas controller, a temperature sensor, and a main controller. The temperature sensor senses a temperature in the grilling chamber and provides a temperature signal accordingly. The main controller is electrically connected to the temperature sensor to receive the temperature signal. The main controller changes a gas flow supplied to the burners according to the temperature signal to control the temperature in the grilling chamber to control the temperature in the grilling chamber.
Abstract:
A smoke removal device includes a connecting tube, a burner, and a plurality of heat storage meshes. The connecting tube has an inlet end and an outlet end. The burner is disposed in the connecting tube and has a flame outlet. The heat storage meshes are sequentially disposed between the flame outlet and the outlet end. The heat storage meshes includes a first heat storage mesh and a second heat storage mesh. The first heat storage mesh is located between the second heat storage mesh and the flame outlet. A mesh-number of per unit area of the first heat storage mesh is larger than that of the second heat storage mesh. The first heat storage mesh and the second heat storage mesh could slow down a flow rate of flame to increase temperatures of the heat storage meshes. The smoke is burned off once touching the heat storage meshes.
Abstract:
A smoke removal device, which can burn the particulates in the smoke efficiently, includes a tube body and a combustion unit. The combustion unit is provided in the tube body and includes a main body, a gas pipeline, and a lighter. The main body is located at a first end of the tube body. A smoke passage is formed between a periphery of the main body and an inner wall of the tube body, and the smoke enters the smoke removal device through the smoke passage. The main body has a central passage therethrough, where a fuel gas is ignited. The fuel gas is guided to the central passage through the gas pipeline and then ignited by the lighter to burn the smoke particulates passing through the smoke passage.
Abstract:
A gas mixer includes at least one outlet pipe and a base having an inlet portion and a mixing portion. The inlet portion has an air inlet, at least one gas inlet, and an air path. The air path communicates with the air inlet and the at least one gas inlet, and has an exit. The mixing portion has a mixing chamber communicating with the exit. The outlet pipe is engaged with the mixing portion of the base, and extends into the mixing chamber. The exit of the air path corresponds to a body of the outlet pipe. Therefore, air and gas can be effectively premixed and outputted to a burner, whereby to accurately control the air-fuel ratio to enhance the combustion efficiency of the burner.
Abstract:
A gas mixer includes a flow splitter and a base having an inlet portion and a mixing portion. The inlet portion has an air inlet, an air chamber, an at least one gas inlet, and an opening, communicating with each other. The air chamber has two opposite walls, which are inclined, and a distance therebetween gradually decreases from the air inlet to the opening. The gas inlet is located on one of the walls. The mixing portion has a mixing chamber communicating with the opening and a burner, respectively. The flow splitter is provided in the air chamber and located between the gas inlet and the air inlet. The flow splitter has at least one through hole facing one of the walls. Therefore, air and gas could be effectively premixed and outputted to the burner, whereby to accurately control the air-fuel ratio to enhance the combustion efficiency of the burner.
Abstract:
A fluid-driven power device is provided, including two fixed plates and a plurality of vanes. The two fixed plates are spaced out a distance, and respectively have two inner surfaces face each other, wherein a central axis passes through centers of the two inner surfaces. The vanes are provided between the two fixed plates and around the central axis. Two connected ends of each vane are respectively connected to the inner surface of the two fixed plates. Each vane forms a spiral twist, and the torsion angle of each of the vanes is changed from a central portion between the two connected ends toward the two connected ends in a symmetrical manner. Whereby the vanes can rectify the fluid, and prevents the output fluid from forming turbulence which interferes with rotation of the power device. Therefore, the rotation speed and efficiency of the power device will be further improved.
Abstract:
A burner includes a base and a combustion tray, wherein the base has an inlet pipe and two horn-shaped tubes. The horn-shaped tubes are connected to opposite sides of the inlet pipe, wherein each of the horn-shaped tubes respectively has a first section. A length of the first sections is no less than an inner diameter of the inlet pipe at where the horn-shaped tubes are connected to. The combustion tray is engaged with the base, and communicates with the horn-shaped tubes. Whereby, gas and air could be fully mixed while flowing through each of the first sections. The symmetrical horn-shaped tubes could direct the airflow to the combustion tray, where the airflow could be outputted from flame vents of the combustion tray, whereby to generate more even flame, and to enhance the heating efficiency.
