Abstract: An electronic device and a control method thereof are provided. The electronic device includes a DSP (Digital Signal Processor). The DSP receives a digital signal. The digital signal includes a plurality of frames. The DSP divides the plurality of frames into a vital group and a non-vital group according to a criterion. The DSP compares a total number of frames of the vital group with a threshold value. In response to the total number of frames of the vital group being greater than the threshold value, the DSP may calculate signal strength of the vital group.

The wasted water is collected in the water tank. The hot wasted air flows from the air blower into the radiating pipe which is immersed in the wasted water of the water tank. The hot wasted air is cooled by the wasted water and is filtered by the active carbon to release a clean air.

Abstract: An air conditioner circulation apparatus includes a receiving tank (2) provided with an air channel (22), an active carbon (3) mounted in the receiving tank, and an air blower housing (4) connected to the air channel. The receiving tank collects water drained from an air conditioner. A hot air drained from the air conditioner is sucked into the air blower housing, and is delivered through the air channel into the bottom of the receiving tank. The active carbon filters impurities in the hot air. The water collected in the receiving tank cools and returns the hot air into a cooled air which has a normal temperature, and purifies the cooled air to release a clean air. Thus, the water and the hot air drained from the air conditioner are removed, and the fresh clean air is generated.

Then, the aluminum plate, the aluminum block and the pot/kettle are stamped at a high speed so that the aluminum plate between the pot/kettle and the aluminum block is compressed instantaneously so as to combine the aluminum block with the bottom of the pot/kettle tightly and closely.

Abstract: A household electrothermal vaporization heater contains a heating body and a cover. The heating body includes a heat tube precast therein and made of thermal conductivity material and a heating channel corresponding to the heat tube and formed in a U shape. The heating channel has an inlet defined on a first end thereof so as to pour liquid water, such that the liquid water flows in the heating channel and is heated by the heat tube quickly so as to convert into superheated steams, and the cover covers and screws with the heating channel by using a plurality of screw elements, thus preventing steams from leakage. The cover includes a plurality of vapor orifices formed on end edges thereof and corresponding to a second end of the heating channel so as to spray the superheated steams.

Abstract: A cooking vessel is made of metal material and includes a vessel body. The vessel body has a heat conducting disc made of aluminum material. A method of making the cooking vessel contains steps of: precast molding the heat conducting disc so as to y form a plurality of ribs or circular grooves which facilitate heating after placing the cooking vessel on a stove and heating the cooking vessel by ways of the stove; clamping a vessel bottom and the heat conducting disc by using a mold on a friction welding machine and rotating the heat conducting disc; pushing the heat conducting disc toward the vessel bottom; friction welding the heat conducting disc with the vessel bottom. Thereby, the vessel bottom and the heat conducting disc are one piece formed securely.

Abstract: A converter includes a heating bar, a water line, and a covering layer. Either the water line or the covering layer is mounted on the heating bar. The covering layer has a helical channel wound around the heating bar. Each of the water line and the helical channel is connected with a water tank and at least one nozzle. When the heating bar is conducted by the power supply, either the water line or the helical channel is heated, with air in either the water line or the helical channel being expanded to suck a liquid in the water tank into either the water line or the helical channel by a siphon principle, and with the liquid being heated successively to produce a high temperature steam which is sprayed outward through the nozzle to cook foods.

Abstract: An oven includes an oven body, a movable tray, an atomized device, and a conveying device. When the movable tray is inserted into the oven body, the second line of the atomized device is connected to the movable tray through the first line of the conveying device. When the second line of the atomized device is heated to reach a high temperature, air in the second line is expanded and evaporated so that the second line is disposed at a vacuum state to produce a vacuum suction force. The water in the movable tray is forced by the vacuum suction force to flow through the first line into the second line. The water in the second line is heated and atomized to form an atomized water which is sprayed on food placed in the oven body.
