摘要： An oven includes an oven body, a heating element, a frame, and an oven door. The oven body has an inner space inside and includes a front plate, wherein the front plate has an entrance that communicates with the inner space. The heating element is adapted to heat the inner space. The frame is engaged with the oven body and has an abutted portion. The oven door is pivotally connected to the oven body and is located at the entrance. The oven door can pivot to a closed position to close the entrance and can pivot downward to an open position from the closed position to open the entrance. When the oven door is located at the open position, the second surface abuts against the abutted portion of the frame, thereby forming a platform outside the entrance for placing objects.

摘要： A pressure regulating device includes a pressure stabilizer including a valve body, a pressure regulating assembly, and a switching assembly. The valve body has an inlet portion, a decompression chamber communicating with the inlet portion, and an outlet portion. The inlet portion has an inlet port for connecting to an outlet opening of a portable gas tank. The outlet portion communicates with the decompression chamber and has an outlet port. The pressure regulating assembly is disposed in the decompression chamber. The pressure regulating assembly regulates the pressure of gas outputted by the portable gas tank to form an output gas with a predetermined pressure. The switching assembly is disposed on the outlet portion and is located between the decompression chamber and the outlet port and is manipulatable to block or open the output gas, thereby regulating the pressure of the output gas outputted by the portable gas tank.

摘要： A disinfection system includes an ultraviolet disinfecting light, a controlling device, and an ultraviolet detecting device. The ultraviolet disinfecting light can be turned on or off under control. The controlling device controls the ultraviolet disinfecting light to be turned on or off. The ultraviolet detecting device is signally connected to the controlling device and is for detecting an intensity of the ultraviolet rays emitted by the ultraviolet disinfecting light. The controlling device controls the ultraviolet disinfecting light to increase an ultraviolet radiation dose of the ultraviolet rays emitted by the ultraviolet disinfecting light after the ultraviolet disinfecting light is turned on and the intensity of the ultraviolet rays is less than a predetermined intensity. An elevator equipment includes a car, a lift control device, and the disinfection system. In this way, the space can be disinfected with the ultraviolet rays to avoid insufficient disinfection effect.

摘要： A burner of a gas stove includes a burner body, a partition member, and at least one flame cover. The burner body includes a gas conduit and a base. The gas conduit has at least one gas input passage for injecting gas and air, and the base has at least one mixture passage for mixing the gas and the air. The at least one mixture passage communicates with the at least one gas input passage. The partition member has a plurality of through holes and covers the at least one mixture passage. The at least one flame cover provided with a plurality of flame holes covers the partition member. Whereby, the size of the burner of the gas stove is reduced significantly, and the gas can mix with the air effectively and uniformly.

摘要： A gas appliance includes a burner, a gas valve, and a control device, wherein the gas valve includes a valve body, a flow regulator, a hot film anemometer, and a stepper motor. The valve body communicates with the burner and a gas source. The flow regulator is driven by the stepper motor to change a gas flow rate supplying to the burner. The hot film anemometer is disposed in the valve body and includes a probe exposed to the outlet passage. The control device executes a control method for the gas valve: sensing the gas flow rate in the outlet passage with the hot film anemometer; comparing the gas flow rate sensed by the hot film anemometer with a predetermined gas flow rate, and controlling the stepper motor to drive the flow regulator based on the comparison result, whereby to stabilize the gas flow rate.

摘要： A wireless signal transceiver device including an RF transceiver, a microcontroller, and a wake-up module is disclosed. Wherein, the microcontroller is electrically connected to the RF transceiver, and the wake-up module is electrically connected to the microcontroller. The power-saving control method for the wireless signal transceiver device includes making the RF transceiver to operate in the first sleeping mode, waiting to receive an RF wires signal, and determining whether there is a triggering signal included in the RF wireless signal or not; if not, returning to step B, and if yes, sending out a wake-up signal to the microcontroller according to the triggering signal so as to enable the microcontroller to control the RF transceiver to change from the first sleeping mode to the first operation mode. Whereby, it is favorable to prevent the RF transceiver from consuming electric power continuously so as to save power.

摘要： A gas appliance includes a burner, a gas valve, an igniter, a thermocouple, and a control device. The control device is adapted to execute a control method comprising the following steps: controlling the igniter to ignite and controlling the gas valve to open; receiving a detected voltage output from the thermocouple; controlling the igniter to stop igniting and keeping the gas valve open when the detected voltage reaches a first voltage value; receiving the detected voltage output from the thermocouple continuously, and controlling the gas valve to close the gas pipe when the detected voltage above a second voltage falls below the second voltage. The second voltage value is higher than the first voltage value. As such, an ignition procedure may be speeded up and the supply of the fuel gas may be interrupted more quickly when the flame is extinguished.
